How many dives out of the 6 (in combination with the Adv. Nitrox) do you have to do with helium for the helitrox certification and whats the minimum helium percentage in this dives? I would like to estimate the gas costs for the course.

What is the buoyancy of this boot ?

I am going through the same process as you. Skill and costs go up exponentially so the time to get there is longer

George Irvine and others went looking for the bodies on at least 2-3 trips. I was on the boat with them on those trips. One dive was a fiasco, with one diver abandoning his scooter that stuck on. If I recall correctly, it was recovered on the bottom on a later dive. I knew the instructor - Andre - he was EXTREMELY unsafe and reckless with his diving, per my personal observation of him on several occasions. I was on an earlier dive with him where a fatality occurred and he attempted to convince myself and others to lie to the police investigators about the details of that dive (presumably to protect himself from violation of dive certification standards. As I recall reading what the survivor said.. The student was having trouble controlling his buoyancy for the whole dive, but Andre did not abort the dive early. My recollection about what the survivor reported is sketchy. I think it might have been posted on the aquanauts list server years ago. Not sure if that is archived. Also, I am also not sure if they were diving those wrecks as described int he video above, I thought they were a little deeper and I never remember hearing the searching divers describe going over any wrecks during the searches, and presumably they had the proper coordinates.

Hopefully next summer I'll do my ext range course with TDI THEN save up for CCR

Does this work with trilam drysuits.

I've written on my wetnotes with both a Milwaukee marker and a Sharpee marker. The Milwaukee ink smudged all over after just one dive. The notes written with a Sharpee are older and are still in perfect condition.

Since i wear a 14.5, should i get a size bigger or get a 14

Do those have bungee cord shoelaces? Just curious. 🤔

I think this is one of the best breakdowns of the back kick I have seen. That includes GUE and Steve Martin videos

It looks like you're swinging your weight into the rotation. Slow it down and smooth it out. It should be controlled and deliberate.

Selling a dry suit without an inflator hose is like selling a car without breaks. Should be criminally liable

Or you could just get a pair of Crocs and some wetsuit socks... By far the simplest solution...

Wanted to get these for awhile now. My boots are wet almost 6 days a week. for the price tag of these boots, I could get 3 pairs of neoprene hardsole boots that will last me 2 years or longer. just don't konw how long will the adhesives last if it's being wet all the time.

I’d love to see something like this but for deep dives (say 100m) where your O2 percentage has to be less than at the surface because your ppO2 is so high (2.31 at 100m).

Hello. Standby for an update video of the midheight version plus a review of the 8 inch tall version.

Glad I found this video. I've been looking for a diving review of these boots, thank you!

There is minimal information available on the incident as only the one diver surfaced that day. The diver who was discovered five months later on the surface was found without his rig. They actually had difficulty identifying which diver he was. I do not know if the other two divers were ever found. The major belief is that the were overweighted with all the steel tanks and that the bungees prevented the wings from inflating to the rated capacities with the dump valve releasing air. No body knows for sure what happened to the other three divers after the sole survivor lost sight of them.

Thanks for sharing! I feel that some critical part of the story must be missing. Let's do some simple calculations: The first diver had two LP95s for back gas (5380 L). He started ascending when the run time was 15 minutes, and eventually ran out of backgas when solving the buoyancy problem. I don't know how much time they spent on problem solving, let's give it a very very very loose estimation of 10 minutes after the start of the ascend (which is crazy long), rendering a total run time of 25 minutes. Suppose at this moment, he averages 230 ft (~70 m). 5380/(7+1)/25, which means he has a SAC rate of 26.9L/min (all the calculations are very conservative, in reality he may averaged over 30L/min), which is incredibly high, even higher than most OW students in their first dive. This is very unlikely to happen in hypoxic trimix level of diving. Was his back gas really full when starting the dive? What's their gas plan? Was there another gear failure? Panic? CO2 hit due to exhaustion? Hyperventilation? So many possibilities. The second doubt is, the whole story sounds like he is way overweighted. But when he ascends, his wing expands, his suit is less compressed, how can he suddenly run into buoyancy failure at a shallower depth? Also note that, when he runs out of back gas, his gears will be 10 lbs lighter than when he enters water, which means the buoyancy issue should be greatly resolved. Is it really because "the wing cannot fully expand", or is there a catastrophic buoyancy failure like a ripped wing or stuck open dump valve? We can never know. The third doubt is, even in the worst scenario where EVERYTHING on this diver failed, in a four-men team there's still way more than enough redundancy to bring him to the surface from 70m. How could this incident turn into a triple fatality? Is there other possible factors? Can it be a bad fill? Mislabeled tanks? Or a second failure on another diver? Anyway there's no way we can know what happened exactly. But these are all factors and possibilities that we should really consider when planning our own dives.

How do you keep the zippers from rusting or freezing up?

Awesome design!!!! Are you going to be at Blue Lagoon Saturday? I'm gonna try and be there for the Gigglin marlin Poker Run. Would be nice to see it and meet you.

Thanks Chris for the good video. I like your idea at 5:50 regarding the use of a double zip tie to secure the necklace to the mouthpiece. Question: My 2nd stage already has a single zip tie which secure the mouth piece to the regulator. Should I replace this with the double zip tie, or place the double zip tie in back of the single one? Thanks.

Why PADI alwayes create a horrible things?

Just did the last trimix dive before the 100. Did 91 today! AMAZING the view of the entire arch. From the 55ish ceiling arch dive, it doesn't look that big.

👍!

What a stupid idea with pony bottle, why not just use twinset ? Much much easier and better

We just sold one to a guy in Alabama. We have one currently in stock. Because of the tolerances and clearances involved, we are only selling them with the center tube and two aluminum STA bolted on already. All the fasteners are included. The system is $150. All you need are the tank bands. We also sell the correctly sized tank bands at $25 each. We are going to be up at Blue Lagoon doing a recreational backmount doubles class / refresher this saturday at 1300, if you want to see one in person.

Do you think that at some point you would stock this setup and sell them in the shop? Or maybe at least the components like the square tube that is already drilled out? May not be the largest market but I'd be interested for sure.

This is the kind of channel that who wanted to be good in diving,, even you are not ready for TEC. I will guide you along your progression.

I'm a Padi Tec 40 and would like to continue my journey with the TDI Helitrox. Can I just switch?

👍👍👍👍👍!

Did you use the walker to silt out the cave too?

Hi there I LOVE your channel. I have a question sort of related to this: I do NOT care about the depth requirements, however, I am interested in the deco theory of it all. MAYBE I might want to do 20meter dive but go into deco limits for photos on a wreck can we just do the theory, part or is there something more like that?

Hallo :) can I dive with Trimix by my own after the course just like with SSI or RAID?

Nice, thanks buddy

Aviation defines an “instrument scan” to avoid becoming fixated on one instrument on the panel. You practice cycling your focus between instruments (and outside the cockpit) in a prescribed order. This applies to scuba as well and can be practiced. Even when solving a complex problem, cycle your focus briefly around you and to your instruments. In time, it becomes second nature.

Thank you Chris those are the points I am struggling with now

👍😎🤿 ! Good one Chris!

Very helpful, thank you so much man.

Do you keep a plan for lost gas / +10m/ft etc?

👍😎🤿!

Being able to shorten or lengthen the necklace also allows you to adjust it for different diving configurations; ie, drysuit, wetsuit or just a rash guard when diving in the tropics.

Yeah, can you please share the dimensions of the spacer? Also, what type of material are you using for the spacer?

7:22 “With some more mathematics” END slide is incorrect. It should be -33 not +33. (200+33)(1-0.3)+33 = 196.1 (200+33)(1-0.3)-33 ≈ 130

Padi don’t know what to say? How much OC trimix are you actually teaching?

Can you share the dimensions of the spacer? I dive side mount most of the time but there a few situations like big waves, small boat or heavy current where side mount just doesn’t fit the bill best and this would be great for redundancy and similar config as I have several plates and wings gathering dust. Thanks for the idea and the material is King Starboard?

Thanks for this!!!! Trying to get my weighting down for my trip to Bonne Terre coming up in 3 weeks.

The air leaking in the video would be going directly into the corrugated bcd hose and then into the bladder. They would result in a fast ascent unless air was dumped and the low pressure inflator hose was disconnected. The major difference between a regular inflator leak and this type of failure is that here both the deflation and the inflation circuits may be connected. So air that you blow into the inflator mouthpiece may also come out of the inflator fitting. What is still a mystery to me, is how the button became unscrewed in the first place.

Hi Chris, great video, the leaks that we hear happens at the stem area and air goes out or does the leaking air goes inside the BCD with a fast ascent risk ? Kind regards

What paper / printer do you use for wetnotes?
