Why use a Rollergun? | ADRENO

- Rollerguns have quickly become extremely popular among spearfishermen, and for good reason. In this video Adreno's Wayne Judge talks about the benefits of rollerguns, also touching on inverted rollerguns.
Rollerguns are perfect for providing extra power in gun that is substantially shorter than other guns. This makes it great for hunting bigger fish in cloudy water and can even be used in blue water environments.
The reason that it has the ability to perform in these ways is the nature of the shaft propulsion. The rollers on the speargun allow the rubber to continue to provide tension right until the spear is released from the barrel tip, as they rubbers are pulled over the rollers. The traditional speargun design provides tension for two thirds of the shaft before becoming slack as the rubbers are pulled towards the tip of the shaft, and so the barrel length is not exploited to its full potential.
Another great characteristic of the roller gun is its natural ability to counter the recoil of the gun. Most recoil is resultant from both the powerbands and the shaft propelling towards one end of the shaft with momentum that needs to be countered by the gun and the shooter resulting in the gun recoiling in the opposite direction. However, on a roller gun there is movement in the opposite direction as the bands move over the roller back towards the handle of the gun. This dissipates some of the momentum required to occur in the backward direction in a smoother motion reducing the recoil of the gun and allowing for a smoother shot for the same power in a lighter gun.
The inverted roller gun is controlled pulleys on the underside of the gun which allow for easier loading of the gun. The rubbers are pulled from the underside of the gun and one from the top, making it a more complex gun to load and manage. However, this is also an effective form of roller gun and great for hunting tuna in blue water conditions.
thanks for the informative review. I've been out of spearfishing for 20 years, so the roller gun is new to me.The inverted roller makes a lot of sense in providing more bang per inch of barrel, but as you said, it's a bit messy.This concept of an open muzzle top is also new to me, but once again, I like the clear view it provides.
Have you measured the power the gun puts out?
I built my first "Man's Gun" in 1969. I fitted a Bazooka Handle & muzzle to a 4' long X 1& 1/4" diameter ally barrel, & powered it with two 28" X 9/16" rubbers. These were each stretched 4' & delivered 90lbs, so I calculated my gun put out 720 ft/lbs. I would be interested to know what the Bully Gun's stats are.
I used 1 & 1/4" barrel because these rubbers on my old 1" barrel visibly bent it under load.Two unplanned benefits of the bigger barrel were more bouyancy making the gun lighter in the water, & the increased diameter meant the spear lay directly on the barrel, which made my gun very accurate.
Don't know if you ever got a reply to this... HELL OF A GUN YOU BUILT THERE! Chris coats has a pretty detailed power chart for rollers on his website. Check it out if you're still interested.
Have fun hunting those whales and submarines with that monster you built.
Cheers from Trinidad and Tobago.
Very interesting, the inverted gun ! Thank you and greetings from South Africa
Hey! Greetings from Cape Town!
It's like compound bow vs regular bow

hate a broken rubber man XD
Really great and informative video on roller guns man! Thank you!
The direction in which the rubber is stretched has absolutely no effect on the force of the recoil.
Newton's second principle!
The recoil depends of:
1. The force on the arrow.
2. The mass of the speargun. The rollergun is more massive and the extra mass absorbs the recoil.
3. The rollergun has no free-swinging rubber at the end of the shot.
Correct. Plenty of other disadvantages as well.
Love these video's!! Think i'm gonna order my Next set of Gun's from you guy's :)
What about the "Fusion" Invert Roller gun? How is that different from the "invert" roller gun?
Fusion: its like a simple roller gun, it just 'replaces' the section of rubber traveling thru the rollers on the muzzle, by a rope.
Invert: rubbers stay at the bottom of the gun. Added pulleys multiply the propulsion force to the shaft.
Can you do a special on PoleSpears for hunting snapper and grouper in holes. What tips are best? What length should I use?
a great tip for polespears is to buy a normal speargun
@@FineArtbySamuel Really good advice
I like a 2.5 meter spear but for caves its a bit bulky go with a 1.8 -2m a flopper tip hits harder and hold fish better as long as there isnt a rock right behind the fish which probably wont happen in a cave
In theory would a rollergun be more powerful if you looped the rubber back on itself twice instead of once so that there would be three layers instead of two? Thanks
"The Bloody Gun".. just perfect
Love the slightly angry (yet loveable) Aussie! Great advice and guidance, I shall be swinging by your store during holidays to learn about the short roller guns for Victorian waters!
it's like a pirate trying to sell you harpoons xD
Oh man, he is one of the loviest lad in person. Knew Wayne from Sydney freediver and he is very friendly and willing to guide people. :)

Hello in friend im Philippines i watching to all video my name Lloyd Aaron D.Nomio my dreaming speargun i hope gift me this account my wife i hope touch your heart thank u for read this god blessed you
Can you kill white shark with it?
Very nice...I just wish you had links to the various items for us new people.
naaaaahhhh it doesn't really have more "stretch power" .... just more bands ....
Simple spear guns i like the old conventional is better those are trouble free like AK-47 rifles
My 130cm inverted rollergun the golden gun is coming🙏🏻
كاكز زة. ذيتر
Wow that is may dream speargun have good quality and long use..watching here from philippines i love speargune sir ..thanks 😊🤗
Hello there, I love your video, very interesting for me. How long take time for get experience hunting myself. I have scuba diving certificate, but I've done not a lot dives. I prefer snorkeling.
please check before that you can hunt with scuba equipment in your location
most of the world have banned spearfishing with scuba
most recreational spearfishers learn to breathhold or do freediving training
also some advice to start with a polespear before buying a short speargun as the next step and do shore spearfishing
@@zazugee yeah, and learn to drive a horse and buggy before you get a car.
Great! So i'm going to cut my Factory made 130 Rollergun to a 110 so it shoots like a 130 standar railgun...
Lol
Check with the manufacturer if your trigger mech can support the change (additional power).
Just ordered getting keen
Sir can you give me a gift like that speargun
Very educational. Bravo
Sorry but roller invert or simple roller nothing to do with normal classic circular .
I have been testing a lot but most efficient always classic double rober
How mach my friends
If youve done your old speargun will please send it to me, i have only DIY speargun...
Wayne, you're invited to Hawaii. Please teach me how to spearfish well.
How Much you cost 1 speargun , if you don’t mind can you let me know thank you sir
Thank you for the proper explanation on the roller gun.
What is the standard lenght of roller type speargun and the size of the shaft used.
Mannysub inverted rollergun130cm my dream speargun
Does anyone know how you would mound a reel on this? (On the side opposite of the double wrap?) maybe you can’t use a reel and need a breakaway style set up? 🤔 🤷🏻♂️
You can use a reel on inverted rollers, at least I've seen videos of it
anyone lives in Sydney? Want to spearfishing together?
You said your 1.10 roller gun give same shot as your convencional 1.30 gun. Your 1.30 is double rubber? What size of rubber you use on it, 16mm on the double?
Hi Jefferson, I made the same experience. I had an 110cm roller that shot very similarly to my 1.4standard gun (2x16mm, 7.5 shaft).
As the shaft is pushed longer on the barrel, this extra time means longer propulsion of shafts, therefore reaching better shooting range.
I also used a beautiful heavy 3x16mm woody bluewater gun, but after a 120 roller (16mm) I just kept using this 1.2 roller. Shorter, lighter, far better maneuverability and I could do quite accurate shots even from awkward angles (soooo little recoil that bent wrists and elbows would work).
Sir.do you have branch here in.philippines.
Bla bla bla $1000 bucks later
I spear gun in the Caribbean sea by Cozumel , which roller do you recommend me? I fish in clear water I need a powerful gun and sometimes shoot at long distance, could I buy you one?
Probablemente un roller de 100 de largo the vendria bien. O uno de 120cm. Eso seria lo que yo usaria en tu lugar. Gomas de 16mm y varilla de 7.5mm.
Wouldn’t just shortening the bands on the old style guns make up the difference? Or no way to get the same stored energy as a longer rubber kinda thing?
Especially with inverted rollers, there is no way to get the same stored energy with an old style gun of the same length.
Me subscribers
How much in 130cm?
I know all about pour trigger mechanisms had a beuchat put double 16mm bands on it itd shoot by itself even with safety on.
When changing setups (bands/shafts) always double check with your manufacturer (or check the specs of the trigger). If trigger mechs are overpowered they will misfire. Very very dangerous...
Hey whats the go with full length rubber on the Rob Allen Tuna? Why do some 1m rollers have different length rubber?
sir good day is 7mm pathos shaft fit to my pathos snipergun 115cm.? the original shaft is 6.75mm...
Yeah probs, most standard speargun mechanisms can take up to 8mm and a difference of 0.25mm is negligible.
bellissimi fucili subacquei .dove si possono acquistare ?
A broken rubber can have life-long consequences!!!
Hhhhh - very true brother :)
How can we from Philippines order that inverted roller gun?
Don't, they are junk. Not worth the bother and don't work as claimed. I got one years ago and threw it away. His reinvents it with line through the rollers as the rubber would bind and not pull or stretch evenly. Theory good. Real life in the water a cruel rip off
So what is your recommendation and how much it cost
wow super amazing.
What is the standard lenght of roller type speargun and the size of the shaft used.
Depends on the use.
Short rollers are nice in murky water. Longer rollers for reef hunting or even blue water (or good vis a vary fish).
The size of the shaft depends on your roller gun length (actually the power it can develop). A 7mm shaft needs less 'power' to be pushed at a certain target distance, than a 7.5mm shaft (more weight as well).
I use a 90cm roller with 16mm rubbers and 7.5 shaft, and the same setup but 1.2m barrel for longer shots / larger fish.
Most used length from what I have seen is between 90 and 110 cm barrels. The 110 IMO is a very all-round and versatile one.
How cost it is, Sr? how can I the rollergun
Conventional old fashioned spear guns i love they work simple trouble free like ak 47
Same thing I am saying
I got a 1100 RA roller railgun but my arms are too short! Even with the stock load-assist bungee-band. The longer load assist (nn-stock) makes a world of difference & I modified the spear shafts with stainless steel wire shark fins. But I shoulda got the 800 or 900 version. Ah well.....
Maybe try and grab the rubbers first, then push the gun to your hip... now you gut the rubbers :) and only need to pull them on the spear.
Or: 2nd option, get a longer load assist
Thats helpful thanks
$300 buy noww Full set
how much
Inverted rollers have to be heavily over powered to overcome the resistance of the pulleys.
I use a Pathos laser carbon roller and it is incredibly fast. does an inverted roller offer that speed? I have seen a lot of guys using inverted rollers to push 7.5mm plus spears on heavy timber and carbon guns.
Hey mate, it really depends on how you rig it. Some of the guys in here are throwing 9.5mm shafts, double wrap rigged at some pretty big fish.
If you'd like to know more head to our website and get on Live Chat or give us a ring. Cheers
is it enclosed track any good for roller?
Never thought about that. I guess is not needed.
The question is why ET are used. Usually to guide the shaft when using LOTS of power so it is 'guided' when fired to make the shot more accurate. On a roller I don not see the benefit honestly.
There is very little recoil on rollers as the shaft flies in one directions, and the rubbers on the bottom retract into the opposite direction.
nice
Sir what the name of your shaft.. Is that a steenlees or pure metal
generally sandvik stainless steel
would you recommend a roller as a step up from my current gun. I got an entry level gun just to see if ill stick with spearfishing and ive grown to really like it. would either go for a bigger gun with double rubbers or a roller.. whats your take?
@@urb6857 sub 120 definitely (if its a roller). Depending on the brand 105-115cm
If you intend to stick with spearfishing probably go straight to a roller. It is more pricey than a standard gun but it's a very accurate, light, easy to use gun. I used a lot the standard circular band guns (and love them) - but once I speared with a roller I got in love with them. I use 99% of my time roller guns.
Awesome. Thanks!
I don’t think so
Good and simple explanation. Thank you!
Top quality Vid Wayne!! Great to see another Ozzie business producing videos like these. Luv ya work!
The Bloody Gun is a weapon!
Excellent!
What in indonesia have shop in bali
Great bit footage guys
Nice guns..
Give mi gan
hi what brand is that Inverter bloody gun I'm interested about it I would like to know more about that gun
Manny sub roller performer made in sydney in australia great gun i have one
mannysub
Awesome mate👌
What brand is the gun on the left? Love the shape.
Hey mate! The one on the left is a Pathos Sniper-R -
