I LOVE my Nova Seawing Gorilla fins. I am 63 and love these. I dove Super Rocket fins for decades, and love these Nova fins.
Me too.

He's like your corny great uncle at the family reunion! Love this guy.
Funny you should say that.
I have a 1/2 dozen nieces and nephews and they have a bunch of kids - not sure how many.
My nieces and nephews all call me Uncle Alec. We're an old family that still respects it's elders (good for me!).
When we have our annual family reunion, I go to each little one and ask them. "What's my name?"
I have them all trained to say "GREAT Uncle Alec" with the emphasis on great!
It's quite humorous and I'm sure in a few years when I'm gone they'll remember Great Uncle Alec.
Thanks for watching.
Alec
Alec Peirce Scuba I just got my open water certification in Monterey CA. Your videos have really been helping me navigate all the differing opinions on dive gear. Thanks for your channel. All the best with your business.
Thanks Aaron.
I know your area. You're in for a lot of fun.
Hopefully your school or club makes dive trips down to Catalina. That's special there.
Take care.
Alec
Another good video Alec! I think alot ot viewers probably don't know that all split fins are products licensed from the original Natures Wing patent from the early 90s. Splits are great for a diver like myself that has spinal problems, less stress on the legs. Splits also require more research. My Tusa splits are much lighter and respond very differently than my Apollo Bio Fins. The Nova is an amazing line and I've only heard one complaint from a lady that said they were just to much fin for her. I blame the dive shop on that case for going after the $$$ instead of putting a smaller framed lady in a setvof Novas. Thanks for another great video.
As an engineer, I always wonder what percentage of a fin is designed by an engineer, and what percent is designed by marketing/sales teams.
Ha good question Dustin.
Everybody knows that red fins go faster
I would say marketing is a good 70% of ANY Product. But especially in dive gear.
Dear Alex, I really appreciate these videos - the main reason being that I get to think about scuba when I'm not in the water.
I live in the Pacific Northwest and go diving all year round. Went last Friday and each of us caught our limit (12 large males) of Dungeness Crabs. We also spearfish (big lingcods), but most of the time we are simply enjoying the view and getting dive-bombed by seals, sealions, and sea-birds, as well are picking up an occasional anchor for craigslist. :)
I use Apollo split fins (spring-straps). I am 66 years old and have had surgery on both knees at least twice. I also use the flutter kick, but also the frog kick on occasion. My spares/backup fins are Scubapro Jets. I have also tried/own a number of other kinds of fins. With our strong tides, I must regularly go against current. I find the Apollos are very effective for speed in current, and my (younger) friends have commented how they can't keep up with me. Part of this is that they are flailing about fighting the current, instead of like me and the fish, who are streamline and hugging the bottom. But a large part is the a shorter strong flutter kick, with the Apollo split fins, that is easier on my knees. Regular fins simply put too much strain on my knees.
My advice is to try out different styles. My much younger son wants the big longer stiffer fins. For me, the Apollo Bio Spit fins are the best.
Thank you again Alex for continue to post these great scuba videos.
Thank you for making this episode on split fins, it was very helpful since I'm looking to buy a new pair of fins.
Hi Alec, I just want to tell you I appreciate all the vids you have made, I have seen them all and have learned a lot. Keep up the good work. Greetings from Norway :-)
Thank you for watching.
Alec
Was looking for fins for training my muscles in water (back issues, training weightlifting) and you sold me on them due to how professional and technical explanation you did. Kind regards awesome and best video I've seen today!
Happy to help Piotr and hope they help with the muscles. If not, return and try another style.
A
I just got my Advanced and Im getting back into diving after a 30 year gap from Open water. I love your reviews and channel. No BS just good info for us rookies. reviews are next best thing to actually trying out the product!
Thanks Joe.
There's no substitute for actually trying a piece of equipment before buying it, but that's often difficult to do.
It's kinda' like getting married! If you could try marriage for a while before signing on, there'd be a lot less divorces!!!
Take care.
Alec
HEHE yes good analogy, I just found your channel and have been spending more time than I should watching your videos. Excellent Channel. Oh my friends been telling me to get the RKS jet fins I tried them they seem ok but heavy to travel with. would you suggest the NOVAs over them I'm looking for all around connivence to travel, durability and efficiency. Thanks
"more time than I should"???
Isn't that like saying, "this beer is too strong", or "that car goes too fast"?
Anyway, I definitely think you should try the NOVA. They will do everything the old Jets do and much more. Plus they are easy to travel with and sure look a lot better! The NOVA fin has all-round convenience to travel, durability and efficiency - Oh, sorry. You said that!
Good luck.
Alec
HEHE I meant it in all the nicest way. I choose watching your channel over work. so addicting one after another continuous play enabled. I work at home off my CPU. I've been watching your videos and not getting my work done. I keep saying one more video and get back to work. 5 videos later and ....... ! Diving my New found hobby, . yup anyways Thanks for the advice. I just bought the scuba pro hydros pro and a bunch of accessories. your $300 or $800 regulator help me make my decision to get the MK25. thanks keep em coming!
i wanted to get split fins, but advised to get the last one you showed. its pretty good. good videos
My Diving started in the US Navy 1970, very good content here, good job!
Thanks for watching Richard.
Alec
Thank you for the review, which made me make up my mind and purchased the Scuba Pro Novas.
Please let us know how you liked them. I used them for a few dives before I really made up my mind.
Take care.
Alec
Great video!
I think the force Fin is the best fin on the market so far.
Lots of divers would agree with you.
I used them and sold them for quite a while but the fad seemed to die off.
Fins are constantly evolving and there are some really good fins available now.
I always say, if you like it and it works for you, stick with it.
But, I also say that you should see what else is available and maybe try others too.
Remember that the Force fin has been available for a long time. It was revolutionary at the time but many newer fins have come along. Now they are the revolutionary ones
Take care.
Alec
I love my Apeks RK3s. Good old jetfin style, somewhat lighter than the old jetfins. Not particularly great for swimming hard(it's hard work), but for a more leisurely pace they're great, frog kick and glide.
Good to know!
A
Tried splits, paddle & the Seawing nova. Now own & swim with the Nova. Great feeling fin. Thanks for the fin review
I like them.
Thanks for watching John.
Alec
Great video Alex, I bought the ScubaPro Split fin, I had a bad knee the time and was told they would take pressure off my knee, they are good if you are finning slow and easy, but to get to a destination and actively swimming they are not efficient and are heavy although they float, they are fatiguing...Will be getting the Nova for this season....thanks for all you do.
When introduced, split fins had advantages many divers liked. However when the Sea Nova's became available they were a better overall fin I'm my opinion.
Take care.
Alec
Great video Alec. It just so happens my wife and I live in the country on a little hobby ranch outside of El Paso, TX. I'll check out your other channel!
Please do. My ranch is not big by Texas measures but it keeps me very busy. Hope there is a few ideas to help you out.
A
I love your videos man, your a real idol to me you’ve taught me a lot
Glad you pick up something new.
Alec
Idol*
Rustic Gaming yeah auto correct did that lol
Thanks for posting Alec.... just subscribed to your at the Ranch video....... Roy UK..
Love your videos.
The Jetfin is said to have been invented by French company Beuchat from Marseille in 1964.
What most divers don't know is that back at the start of recreational diving, the majority of manufactured gear came from Europe. France and Italy were big suppliers before US based companies bought patents or started their own ideas. Watch some of my Vintage Scuba to see what it was like back in the stone age of diving.
Great energy and great videos keep it up sir.
Glad you like them!
I love your videos and respect your knowledge in the industry.👍
My personal preference is the original gorilla fins by scuba pro.
Along with the jet & rocket fins.
Thanks for sharing Mitch. As you get older, like me, the foot muscles can't take the arch stress anymore. If you feel foot aches after a dive, may be time to test one with a full foot platform.
A.
Interesting info!
Thanks for watching Justin.
Alec
Thank you for sharing
I would say that the split fin is great depending on your general purpose. If my next photo op is to the next bommie then the split fin is better for getting me there in good time without too much air, but maybe not as much control when I get there. For me it's a more straight line kick and I get accustomed to that. For Deco, wreck and other diving, I use a more traditional fin.
Everyone has a preference and that's why there are so many choices in fins to pick from. Thanks for watching Amadd.
Have ScubaPro split Jet Fins really like them, but they are heavy...really like those Nova fins, thanks for sharing.
Yes. The split fins are not light. They need a lot of support along the edges to keep them fin-shaped so the weight goes up.
The Novas on the other hand, are really lightweight - good for travel and saves a lot of energy when finning.
Take care.
Alec
The weight is generally an advantage for coldwater or dry suit setups. It's just another way to distribute weight and work on balance and manoeuvrability. The jets have become my favourite snorkling fins as well, because of how natural the response is, and because of the power they afford. These are the old ones, with no added silicone to the mold. I even do most of my spear fishing with jet fins.
Hi Alex, Split-Fin. I tried these when they were all the Rage. However, I found I could not swim backwards by moving my ankle and not my legs. Why? Simple, when filming I use my feet from the ankles down to manoeuvre forward and back would to Zoom my Camera(Video) to the correct distance from the subject and stay in position. And I found the Split-Fin did not work at all for this technique, because it did not capture enough water at slow speed. I found the best Fins for this had these 2 features. The whole of my Booties goes inside the Fin, which takes the strain off my foot. Hence the back of my Fin supports the underside of my foot. The Fin also stays on when you do a Scissor entrance (Grand Step) into the Water from large Boat. Hence from higher above the water than a small Boat. And the Fin stays on!
I tried them all & one thing I am certain about is split fins don’t work well in a current as the vortex created that the fin pushes against gets washed out of place.
I have felt this & seen the difference in & out moving water. I actually would choose the split fins in a quarry but in the ocean I don’t use them anymore.
Force fins (the short duck feet type) work well but my favourite is aqualung slingshots...noticeably better than anything else I tried.
Glad you researched and tested them before finding something that you're happy with. Not a lot of divers do that.
Safe diving.
Alec
I love my Tusa Xpert Zoom full foot split fins. Extremely light weight, no pressure on knees or muscles, provide sufficient open warm water propulsion, never came off foot even in terrible drift dives, and cheap. Too bad they were discontinued. I will be sad when they completely fall apart. 15 years and counting....
If you love them then stick with it. Kevin still has his split fins (and even dives with them sometimes shhh.).
A
Hi Alec,
The scubapro nova fin, had an insert in the foot well, which you took out on the video, I've noticed that many fins have these when bought new, my question is do these inserts have a purpose, I've asked many divers and store owners, but no one seems to know the answers, I personally leave them in as it makes taking off my fins easier when in my heavy dry suit, just thought I'd ask as I'm sure many other divers may wonder why, as most footwells are ridged anyway, many thanks.
Only purpose they have is to keep the shape of the fins foot pocket
That's it. Some divers have mistakenly thought that they were valuable. Some thought they were spacers to help the fin fit properly.
Nope. Packaging. I tell divers to throw them out. That way, when they lose one, inevitably they do, they won't be upset.
Alec
about that last fin, how does it holds if you frog kick, or backward frog kick? I am interested after watching this video, but i use usually only frog kick
The Nova Wing fin is great for every fin kick. Although light, it is remarkably stiff and will hold it's shape regardless of the direction of the kick. It's hard to describe and harder to impress upon you how it feels. You really need to try it.
Go to your local Scubapro dealer and ask to try one. I gotta' believe he'll have one from rental or from a staff member that you can use. If not let me know and I'll call him!!
I think you'll be pretty pleased.
Alec
I don't think I've seen you more enthusiastic about any single piece of equipment as you are about these scubapro fins... It's at least the 3rd promotion video you've made. I'll give you two things though, I like the obnoxiously all-yellow colour choice and I like the low weight.
Great Alec thank you! What about the new sport fins? Have you tried them?
Not yet!
Hey Alec really nice vid again ! ... btw just got my aow and peak p b this weekend ;) was fun to try the deep dives ... I wanted to know ... the one you like they are the nova fins right ... not the guorilla ? I was asking as the guorilla I got I found really stiff and didnt get the nova as some were saying too soft ?? You find the nova could stand normal to soft current easy or on the sift side ? This weekend I dove with some mares excell + ... not bad at all but the nova are nagging my mind haha .... thanks in advance for your input .... going to watch the ranch series also ;)
Alec Peirce Scuba thanks again !
The "wing tip" part, is called a WINGLET in aviation. There are actually on MANY high performance aircraft; airliners, privet jets, gliders and many other aircraft with the goal of great aerodynamic efficiency.
Thanks for explaining the terminology Erikk. Wish I had a jet to travel to warm dive sites.
@@AlecPeirceScuba_SeaHunter LOL me too. I am a Pilot wih out a plane at the moment...(not that I can afford to actually own one anyway.) I really love your videos. I am making my way through the SCUBA Tech Tips at the moment and have watched some of your ranch videos...spacifically on your fireplace heating system.
I like this guy, haha!
Yeah. I laugh at him too, all the time.
Sometimes I watch my own videos and find myself shaking my head at the antics I do.
But heck, I'm having fun and some divers seem to enjoy it so ...
Thanks for watching.
Alec
What a cool guy
Thanks Pero.
Dear Alec,
concerning the holes, that are very close to your foot: Don´t they prevent from negative resistance as your foot is more looking upside down compaired to the blade itself? So, better to let the water run through as to build up unnecessary negative resistance with your foot?
Would love to hear your opinion :-)
I have watched numerous videos demonstrating fin performance. While your point is good, the thought of eliminating any negative resistance is seldom addressed. Divers generally feel that they get propulsion on both the upward and downward stroke. The downward stroke or power stroke is by far the greatest source of power. The upward stroke or recovery stroke is much weaker and is really a relaxing stroke to get the leg and fin ready for the next power stroke. It could be compared to the exhaust stroke of a 4 cycle gas engine - no power goes to the crankshaft but just wait a second. Power is coming!
Negative resistance occurs on both strokes and tries to slow the fin down. It actually takes energy to overcome. Negative resistance is greater on the power stroke because of the velocity but if measured accurately, balances out on the 2 strokes because the same distance is covered on each.
Over the years there have been attempts to negate negative resistance. Healthways had fins in the 60's that featured a flap over a large hole. The flap closed and provided a full blade to the water on the power stroke but then opened so the blade area was reduced on the recovery stroke. Neat idea but the benefit was minimal. Certainly when compared to the cost and complexity of the fin. An open hole would benefit (or not) both strokes equally. I know that both Aqua-lung and Scubapro spent a lot of money "proving" that their vented fins were better. I'm not so sure they succeeded.
I think that mask technology has reached a zenith so maybe we'll see some new fin designs in the near future.
Thanks for watching.
Alec
Hi Alec, can you please make a video about scuba diving using long freediving fins. Is it good or bad using freediving fins for scuba. Thanks a lot.
That's an interesting idea Ayem. I'll add it to my list.
Hi Alec, I’ve just completed 14 dives with the new fin clip have attached to my Tusa split fin ... my opinion they will revolutionise the diving industry ... a little apprehensive when I first tried but after doing a couple of boat dives just forgot they were attached ... great for zodiac and shore dives ... love your vids 🇬🇧👍🐬
Much better than the old rubber straps held by metal pins. Boy, they were a nail-breaker.
Take care.
Alec
I was hoping you'd compare them to the nova's. I've owned several fins and the bio fin is my favorite at the moment. I'm upgrading gear in the spring and the Oceanic OCi computer and Nova fins are definitely on my list. Just trying to decide on the bcd. Keep jumping around between the Scubapro Hydros, Glide x, or Seahawk. The shops around here don't only sell one or two brands and only work on stuff they sell so mix matching beyond the computer won't be ideal unless I disassemble and go to several shops. I'm leaning towards the Hydros but that is a big chunk of change and not having pockets is a bit of a downer but I know I can mount a pocket and add the loops. I'm trying to be less of a christmas tree under water so part of this is a good thing. Also going back and forth on the air2 or not. I watched your video on the bcd regulator but still kind of appeals to me. My biggest problem with the air2 is where I use my gear. I never have the same buddy twice from trip to trip since I none of my friends or family are into scuba. Kind of risky. For a weekend lake dive or 2-3 drives per day at a cruise destination.
I dive back plate and wing with one pocket, and the whole set up cost about $400, but thats my thing. I also own an Air2, I dont use it unless I decide to put dive with my zeagle ranger, almost never, but I will say if your buddy needs air they arent going to stop to look for your safe second longer than 1 second. If they dont have air they wil take the one out of your mouth, which is fine, and can be expected in a life threatening situation. You were just breathing, they weren't. You are the one that should practice with your Air2. know where it is, know how easy it is to reach and to use. In the end a panicked or desperate diver will take any air source they can even if its in your mouth. Just know how to calmly reach for your safe 2nd without adding to the situation.
Could the holes be to prevent an air bubble from becoming trapped in the fin when putting on the fin?
I've seen fins get so tightly stuck on a diver's foot that it needed 2 other divers to help ull them off.
But I think just a couple of small holes in the toe of the foot pocket would solve that.
Alec
Anyone else wish they watched this video before getting $200 fins
Thanks for watching.
Alec
hahahaha you made me lol'ed.. Sorry for that though
I am watching before replacing mine from 1988! My mask, fins, and snorkel back then ran about $150! - I needed a mask for a petite person
Hey, maybe a little late asking, but do you regret buying split fins?
Alec I've been looking at getting a set of scuba pro novas and I saw that they now have a nova gorillas which are described as stiffer. I was wondering what your opinion on stiff vs less stiff fins were?
I'm a runner, and I have both the Novas and gorillas, to me they almost feel the same but the 3 other people that have tried both can really feel a difference. One person got a cramp the gorillas after only 10 mins of finning around a pool. If you have strong legs or are a large person then maybe consider the gorillas
Slick85 that's what I've read while googling them thanks for the actual comparison. I have a bad habit of fining too hard so I'm thinking the stiffer ones will be a better fit
Mr. Peirce...I enjoy your channel greatly and was wondering if you could help me with a "quick fix"? I have a pair of original Voit A6 fins that are ripped in the heel area and would really appreciate advice on how, if possible to repair them...THANKS SO MUCH FOR YOUR TIME>
Gosh i'm sorry.
I have several pairs myself and at our vintage dive events there's always a couple.
There is no way to repair that old rubber. It may be time to retire your old Voits. Clean, them, put them into a frame with a picture of yourself diving and you can tell your grandkids that you used to be a frogman.
There's no glue or tape that works that I know of.
Maybe another viewer has an idea.
Take care.
Alec
Church I’ll. Body surf fins are good for Scuba.Im always buy ing flippers that are sized extra large, so I can put my reef walking shoes inside.
Good idea. Divers use dive boots for the same reason.
Alec
I thought you said "i like beers" in the intro haha
I do!
I'll used the nova for some dives to test it, but at the end I got the mares x-stream just because they work better for me (except frogkick 😅)
You seen it here a dozen times - what works for you is what you should use!
Take care.
Alec
I had wondered about the bungee style straps longevity. Thanks.
Bungies last as long as rubber or steel springs. You have to take care of them rinse after salt water diving or the salt erodes the bungie. They are easy to replace and very comfortable. Try different fins on at your local dive shop to see what you like best.
How do you replace secound stage spring and valve seat if adjustment doesn't stop hiss
That is for a service tech to do as it will be difficult to get factory parts and the service book. Do check the hose crimp to ensure it is not leaking.
@@AlecPeirceScuba_SeaHunter it's not leaking at hose I adjusted up it quit but does anyone ever change the those seats and springs? Saw your video on servicing secound stage noticed you did nothing with spring and seal seat
I really enjoy your vídeos, where can i get the yellow fins?
They are Scubapro Seawing Nova fins. Any Scubapro dealer has them or, if you LDS doesn't have them, get them online.
I can guarantee you'll like them.
Good luck.
Alec
Which type of fin is good for currents. I've "heard" that split fin don't do well in currents.
Split fins generally aren't good for current diving, they are less efficient than blade fins. However you need to take into account your own physical abilities. If you have a large stiff blade and youre trying to power through a current for good amount of time, your calves, legs, ankles, may start hurting or even worse cramping. If you manage to pull through without ant cramps you'll be tired and youll probably be burning through your air. Try a bunch of fin types and stiffnesses to see what suits you best in the type of conditions youll be diving the most.
I wonder if those "new fin style" engineers ever tried to do something else than standard owd flutter kick. For me a good fin must also perform well with frog kick, helicopter turn and back kick. That rules out most of those new fancy designs.
That's one reason why I have suggested the Nova fins as a good choice. Despite its odd look, it is really just a normal single blade fin. It's actually a lot more like the Jet Fins than you realize until you see them side by side.
I use the Flutter kick almost exclusively because I'm old and I have a slight impairment in one leg but I have used
the Frog kick and others as well. There's no reason why the Nova wouldn't work perfectly for them too.
Maybe someone can comment on that.
Thanks for watching.
Alec
Alec Peirce Scuba they work great in any style of stroke just be gentle for the sediment. There I find my splits actually very good believe it or not.
Thanks Keith.
Alec
My current pair of fins are the Nova's just like you were showing in your video. I find them very powerful for the amount of effort you put in. However, I've recently tried doing the frog kick with these fins and find it a little bit difficult because of their length or maybe also because of their design? I picked up a pair of the old tried and true Jet fins and I'm going to try them out on my next dive. Curious as to what type of kick you are using when you are using your Nova's. Maybe it's just me and I still need to get the technique down? Thanks for your videos. I am able to glean a good amount of info from them. Cheers!
Not sure if you've heard of innerspace explorers, a technical diving training foundation. They are hardcore DIR style divers, and this is one of their top instructors reviewing the Seawing Nova. He doesnt care about brands and new innovations. He is a tech diver that mixes and matches all his dive gear to make his diving safe and efficient.
ua-cam.com/video/1YeSxN97uuo/v-deo.html
He mentions so pros and cos of them but he demonstrates the different style of kicks.
Thanks for the link to their video. I did watch it and he does make a point. A skilled diver would most likely be able to do any of those kicks with any fin on the market. However, I'm hoping to find out between the 2 sets of fins I now own, which one is the better tool to do the frog kick (assuming I got the technique down pat). I guess I will find out soon enough if it is easier for me to do the frog kick with the Scubapro Nova's vs the Scubapro Jet Fin.
@@jimilborillo I'm curious how your comparison of the Nova to the Jet went? I'm considering both of these also.
@jimilb Thanks for the info -- I'm leaning toward the Nova for the lighter travel weight -- I'm always nervous close to the weight limit when checking in my bag of scuba gear!
@@rob_9876 You'll definitely like the Nova's for their weight savings but they take up more space than the Jets. For travelling via air where weight limits are a concern I will pick my Nova's every time. You can also consider just using house fins, but that is always a toss up. Good luck!
Great
Don't stop.
so you dont believe that holes next to the foot reduces drag, but the hole in the end you believe in?
Healthways had a pair of fins in the 60's that had holes just like the Jets or Rockets but, there was a flap over the holes so they only opened on recovery. During the thrust kick you got full surface.
Re the holes, I was just never convinced that the holes in the center of the blade actually helped. The small hole at the tip of the Nova was put there as a result of research and testing. Apparently it help efficiency although I'm sure the benefit is so small as to be unnoticeable by any diver.
Alec
Fish don't have split fins .....
Anyway I've used Mares fins for over 30 years and perhaps four or five years ago I switched to Hollis F2s for more of a travel fin as it's shorter and lighter (fits in my suitcase). That said I use my Mares fins if I know I'll be diving in strong current (Hollis F1s are too heavy for me and the F2s don't quite provide the power).
Quite a few people I know are using the SP Novas and I might just ask to borrow a pair to find out if they really do make any difference.
Good points Gordon. Every diver has different preferences that's why there are so many choices. Not like back in the stone age, only 3 fin options: too big; too small; close enough! Thanks for watching.
actually most speedy fish have caudal fins much like a wider split fin
Hey Alec I love the videos
Thank you Andrew. More coming to keep you educated and entertained.
Alec, I have a pair of Scubapro Twin Jet fins, I just got a set of spare straps,just in case,those straps came with buckles that attach to the fin with a stainless pin, how do I take the old one off and install the new one? I can’t find any info on this anywhere thanks!
First, let me revert to the vernacular - it's a bitch!!
The old pins are riveted in place. You literally have to grind or punch out the pin.
Invariably that destroys the old clip (the U-Shaped part).
Your dealer ought to have got you a new set which can be changed over. Some use a long bolt and locknut. Others re-rivet together. Go here online.fliphtml5.com/tzzi/splr/?1519576582796#p=335 or find a Scubapro Dealer and ask him to get you a clip set for old Scubapro Jet Fins. They are the same and will work.
Either way it's a pain in the butt.
That old fin is still around which I find hard to believe but lots of divers like them.
Maybe I'll do a video on changing the straps and clips.
Thanks for watching.
Alec
Alec Peirce Scuba ,thanks so much for the reply Alec,mine don’t need to be replaced,I was wondering why they give you a replacement pin that you can’t replace,?! I like the bolt and locknut idea,thanks and love your videos!
Faced the same problem recently.. a small handsaw took care of the old metal pieces.
So it sounds great with kicking. What about with frogy, does it work well?
Yep! There's a current fad among Tech types who swear by the big, old rubber Rocket fin.
The Nova is very similar but with a much more sophisticated design - more efficient in every fin stroke.
Any diver who tries falls in love.
Good luck.
Alec
I disagree. Sure you can frog with anything - but tech requirements are usually different from just regular diving. A lot of gear is hauled and the balance is different so a soft fin that allows you to change the position of your legs in the water withour using techniques that may be a little more difficult to pull off when you are loaded.
But there is no real power in splits when frogging, they're just easy on the joints and muscles if you are not a strong swimmer and they allow you to move your foot about more freely in the water column if you don't have the technique to manoeuvre to any position with a stiff finn. But it comes at the cost of precision finning because they don't "stick" in the water column and give you a pivot point like a stronger fin would.
Which is also why they accellerate poorly on a single fin stroke. The trouble with these in current or strong surf is that you have to BUILD power or speed gradually. You can't muscle through and get an immediate effect. There is not enough power in a single fin stroke as it would be with say a classic mares fin. If you push harder than the fin is able to transfer it just bends and wobbles and the effort is wasted. That means you have to work continuously with softer and smaller movements but much faster as opposed to a stroke-rest rythm and your working pulse and air consumption will increase.
If you are a guide or instructor it also means you can't do a single fast and strong kick to accellerate fast over a short distance to catch some student or new diver on a runaway ascent.
Anyway - split fins are fine for covering a lot of ground, especially surface transport with a minimum of muscle effort or hauling a load - but that's not what most people do or aim for when diving. Sure splits may take off some the strain on your joints and muscles or save the odd cramp if you're out of shape. But in current or strong surf - you'll have to work either way, and split fins will be weak sauce for many core manoeuvres and just generally less flexible in terms of technique. In caves or wrecks.they offer less precision as well.
How many people have I seen floundering, heart pounding, breathing heavily, sweating in their mask and hogging air trying to build and maintain a steady pace once the current picked up ... the answer is - I see that every time the going gets tough.
I'd say I've done about a hundred dives with split fins and I have just long left them behind. When would I choose splits? If I had to do a long laborous surface swim at a fair consistent speed - their forte is when you gradually build that and maintain it. But there is an upper limit to what they allow you to work against that way. I might also choose to us them if I had to carry a lot of tanks for a deep dive and had restricted upper body flexibility. Could be they also offer some steadiness when filming, due to the soft attack, at least in calm water. In cold water coastal scenarios they allow you to walk about on the sand with fins on in the shallows more freely, which can be a teaching advantage if you are helping student divers on O.W 1
But frankly, other than these specialised situations, or the calm pool-like scenario - I think they are too unreliable in the grand scheme of things.
I'm afraid my question was not very clear. Sorry about that. My question was related with the Nova, since it is the final and longest analysis, not split fins.
@@andreguiomar7690 No problem man :) personally I use different fins for different things, but my goto will always be a Mares plana avanti or quattro fins. Not the newer "superchannel" which is soft and folds in current. I guess there is a reason that these are the fins you see more often and not with guides and instructors. They just get the job done, when the going gets tough ...
@@whynottalklikeapirat yeah, Avanti 4 for me as well. But I always enjoy testing new stuff :)
Great video! Guess my split fins are dated:(
No way!

Scubapro still sells split fins. As does Tusa and Atomic. I'll bet they've all done the research in a "water tunnel" and can see the advantages of the split fin design. Split fins are more efficient than standard paddle fins. My personal experience is the same. For the standard flutter kick, split fins rock and paddle fins suck. I say that having tried both fins over long distance...not just a short sprint. Not only are the split fins faster, but no leg cramps. That said, when I want more maneuverability, and I don't need speed and/or I'm not worried about fighting currents, I wear paddle fins. Back kicking is easier with paddle fins.
I'll guess that some of the more futuristic fin designs are attempts to have it all. Something with the ability to maneuver like a paddle fin, but the efficiency of a split fin. That is likely what Scubapro was attempting with their Seawing Nova. Not quite as efficient as a split fin, but better than any normal paddle fin. And easier to maneuver in than a split fin. I haven't tried the Seawing Nova's, but I'm interested. And the light weight for air travel is another advantage.
I think you'll like the Nova.
It's quite a bit lighter than the split. Splits by their nature are heavier. The ribs must be stronger and the fin itself is thicker to stand up to the flexing.
Most shop owners I speak to tell me that splits don't sell as well as they used to. I think they were a novelty.
If you like them, stick with them but be sure to get a pair of Novas to try.
Thanks for watching.

I'm looking into getting certified very soon and buying all the personal gear and I was hoping this video would provide a little more clarity about split fins instead of spending half the video talking about those scuba-pro nova fins again. From what i've read, people who use split fins tend to love them, people who mainly use paddle fins tend to disregard split fins as terrible in currents, cant go backwards, cant frog kick. I've read that splits can be decent at frog kick but aren't as good at going backwards. And if you are diving in strong currents you need powerful fins to fight against you are burning through your air at a rapid pace. I don't know if split fins are the best for me right now but I also did read they are better if you have knee issues. I was hoping for a little more "from the horses mouth" advice on this one though.
I dont like split fins personally, I think they are very over rated but as you say some people seem to love them. The best thing to do as a new diver is try all kinds of equipment and see what works best for you. I prefer lighter and efficient fins that are easier to travel with as Alec mentions about the ones he uses. It helps a great deal when traveling abroad and reduces leg strain underwater. Have fun with diving and good luck with your certification!
I'm 70 and have a problem with 1 leg.
I need the most efficient fin possible - light but strong and no wasted effort.
I've tried them all - solids, long, short, several different splits and most recently the Nova.
The reason I spent a longer time on the Nova is simple - it's by far the best fin I've ever used. Any stroke, any time, easy to pack and to use, comfortable and so easy on my old legs yet i can keep up with the best of them without a strain.
I can't help but suggest you try them. I believe you'll find them excellent.
Alec
So funny!
I do try to make it fun. Thanks Manuel.
Do you still stand by all that you’ve said here? Kinda feels like a Nova add with a lot of misinformation.
Funny how Alec has replied to almost all other comments but not this one.
I will stay with my Dive Rite fins:)
As I always say, Tom, if it works for you, stick with it.
Take care.
Alec
Split fins are great for straight ahead in horizontal position propulsion, and are completely inappropriate for anything else , ie maintaining any type of stationary position mid water. Useless in caves, wrecks. Wish there was a way to switch gears so to speak , a split for transition from shore to dive site and back, and a straight blade once UW
There has been so much innovation in scuba gear since I started in 1958. In a few years there may be a lever on fins for Power or Normal use that changes the fin flex strength. I remember when the first SPG Sea-Vue gauge appeared and thought, diving can't get any easier than this!
Lots more to come so thanks for watching.
Alec
Split fins are great for open water, but bad fins for caves and wreck penetraiton. They make too much dust.
I loved split fins when they first came out. It was one of the earliest and best attempts to actually design a fin for efficiency.
Now they are far from the best choice for several reasons.
Thanks.
Alec
In aviation, those vertical projections at the end of the wing are called winglets. Just FYI.
I like that - winglets.
Thanks.
Alec
Reduces spanwise flow, which reduces induced drag and increases range.
Well that's my next fin.
But Your say The Fins "must be" a bent ..... But advertisement Fins ScubaPro from my look - they are strait like a piece of wood ....
The NOVA fins are not like most so some generalizations don't apply. They actually do have a small bend but since they are designed to provide power on both strokes, the bend is minor and not always noticeable. You can see it when they are on your foot.
The reason for the "must have" bend is simply that the fins should point straight back while finning. That is, assuming your are swimming horizontally and parallel to the bottom, the fins should also be horizontal and parallel to the bottom. But because of the angle of the ankle, the fin must be bent a bit to accomplish this. You cannot point your fins straight back without breaking your ankle!
In the end, flat or bent, it's the comfort and the efficiency of the fin that matters and that may be different for different divers. Some divers like a stiff, straight fin. Others a bent or curved fin.
I suggest you try lots of fins if possible until you find the one that gives you comfort and efficiency.
Thanks for watching.
Alec
According to ScubaPro, the Seawing Nova's pivot results in the fin bending as soon as you start kicking. They also claim the angle of the blade stays about the same regardless of how hard you kick. So...the Nova's don't act like a straight fin in the water.
Yum Yum Yellow
Bright fins area good idea. In warm water they help your buddy find you in a crowd; in fresh water they stand out even if it's a bit muddy.
Yum Yum Yellow or Day Light White. Your choice.
Alec
Alec Peirce Scuba thanks for replying. Great point about standing out but is it not true that sharks are attracted to the Colour yellow
Scubapro should sponsor you
I don't want any sponsors, lots of scuba channels have them. This is for me to share my 60+ years of diving and store ownership without caring about who might not like it.
👍
Thanks Joseph.

Watched a lot of vids on UA-cam on this subject.
Yours has been the only one that actually dicussed physics and function.
Thanks for continued good advice on Diving.
The way this dude says Logical reminds me of Norm MacDonald
A great comedian and Canadian. Sadly missed.

As for me pins are cumbersome i prefer flipflop
If you have big feet, don't need any fins, just like my buddy Kevin.
A.
I am an old man.... ORCA fins which look like Duck Feet. Now using Cressi long fins. I think some of the modern fins have a "low IQ". Get in shape, swim laps, and dive with a decent fin.
Good advice for all us.
A
Ambidextrous? I'd give my right arm to be ambidextrous.
How can I fix Bent or wraped fins?
They probably got bent from being held in a bent position in your dive bag or on the boat. All you can do is bent them back and hold them in place for a while - days maybe, and hope they straighten out.
Alec
Yeah, that hole is for hanging your fins, or tying them together. That tiny hole does nothing for your finning.
I agree.
A.
Wish I saw this videos months ago. Just bought some junk fins.
Sorry.
Unfortunately, most dive store staff are taught to sell rather than meet needs.
I've actually heard store owners tell the staff to sell a particular model of fins because - they were overstocked!!
That's the store you want to go to huh?
Take care.
Alec
Split fins are dumb...
An attempt to improve things isn't really dumb. Misdirected maybe but as usual, such fads fall by the wayside. I predict that sometime in the future an old diver will talk about the weird split fins that we used in the 90's and all the divers of the day will look in amazement at them.
Today's mistakes are tomorrow's fodder for comedians.
Take care.
Alec
I dont understand this. While are you still making Scuba 2000 videos. You sold the company and retired?
Those are green not yellow...
Ooops.
Just an opinion
Split fins: useless. Inefficient. Gimmick
Jet fins: wingtips are for aircraft. Not streamlined. Inefficient. ( SP nova)
Spring back happens if you have quality fins.
Last time I looked at a fish it had none of these qualities.
Nature make efficient shapes. Engineers make gimmicks
You would love vintage gear, every engineer's new design claimed a miracle will happen if you used it. Remember they even sold Cold Cream on the skin to prevent chilling, using that new and safe asbestos of course!
@@AlecPeirceScuba_SeaHunter nope. Vintage gear is old. Open heel fins are also crap IMO. All I see are people losing fins or adjusting straps. I stand by my statement, with experience and common logical sense.
Geeze tough crowd it seems lol
@@Blink182fan182182 I think we can all agree that people fall for gimmicks. People spend hard earned money on this type of equipment only to find it doesn’t live up to expectations. If you think my comments are tough, try the equipment and it fails and you get put in a life threatening situations, you’d be “tough” in your opinion too.
@@UA-cam_user3333 It's just let's be honest nothing is perfect. You can't just say everything is crap. If you scuba you have to use something. There are compromises that must be made with anything, and you just have to look for what gives you the most of what you want and the least sacrifices. Don't get me wrong you're definitely entitled to feel anyway you want to I just felt you were being tough about hating everything when clearly you use something you like. What do you use so we can get insight from this and maybe get a new perspective?
Great
Thanks.
Great
Thanks.
