Thank you for this video - Good Job! I am a diver with hundreds of dives and many years of diving. I really like to watch diving videos as a way of reinforcing my own skills. But, so many demonstration diving vids are done in warm water. Where I dive in the Pacific NW, heavy gloves and hoods are necessary and I use 7mm farmer johns and some use drysuits, but the restriction of vision, movement, and feel in cold water makes things very much more difficult - I'd like to see cold water demos.

@a6km I believe you've only met the stuck up divers of DIR. There are other DIR divers who focus more on the whole approach and aren't out to change minds, they'll just defend their position if asked.

I do not believe the short backup is dangerous when you dive DIR, or dive inspired by DIR. You will usually have multiple divers in your team and take your redundancies through the use of planning and teamwork. It's a different mindset. To each their own.

@g1138Cypher sure you can`t eliminate all risks but the problem with DIR is that everything else if its not DIR is bad and Lame or how they call non DIR divers. As a holistic approach that short octopus for example is just dangerous, we use a standard 90 cm hose for it just in case all goes wrong scenario. It is just making sure that we minimize all the risks. Thats why we use different manifold setups as well but when we showed this to DIR divers simply they laughed at us.

[g1138Cypher]

@a6km DIR is a holistic approach. You simply cannot expect the gear config to work unless you take into account every other aspect behind DIR.

Your gear should be maintained, you should self check it before each dive. Dive planning should take into effect personal and backup gas plans. When all of this is taken into account, the chance of a diver in the team running OOA is low, and the probability of two primary regulators from two seperate divers failing is low. (cont)

@Indreq to number 5 thats why i dont get why DIR idiots using such a short secondary hose to their backup regulator. still if the main one fucks up you could use the other one for both of you. With that short piece DIR uses you have no fukin chance at all

@Lolcatwitwut Pure oxygen becomes toxic around 25 feet. The "Air" mix standard in scubatanks is 21% oxygen. Do the Math and its around 220feet that this becomes toxic. Which i where Trimix comes in. Helium is added to the mix. but Helium is becoming extinct and prices are on the rise!

@Indreq It is an extremely difficult situation. The only way to do this with any reasonable chance of success is through practice. Especially if you intend to do these dives with only 2 divers. I have fortunately never been faced with this exact situation, however I have experienced a diver suffer a seizure (Undiagnosed Epilepsy) while at a dive floor of 35m. Fortunately it ended well as 2 other divers were able to assist fairly quickly and we had only been at depth for a short period.

Im Sorry But I Thought He Was Dancing.

I find it rather interesting that oxygen can turn into toxic when you dive too deep underwater in the ocean. It would be a nightmare if you experience that because the chance is 99.9% that you'll die.
