Before taking the Adv Nitrox/deco procedures course, I would never have thought of a DSMB as a way of controlling buoyancy! Great skill to learn. Also wondering what the procedure would be for a faulty drysuit inflator - disconnect, isolate, shutdown?
Hi Eddie, good question. For the drysuit inflator malfunction, no need to isolate as you would already know which 'side' aka which first stage the problem is. So you can go directly to dump gas, shut down, disconnect. If it's a smaller, constant inflation, you may have enough time to disconnect straight away
Why did you have to turn off your right post and change regs before disconnecting the LP inflator hose- this takes way too long and its easy to disconnect the inflator hose under pressure- just makes a "pop" and then manage the wing inflation orally!
Hi Colin, great question. Have you ever had a stuck inflator button? In that case, a lot of gas is pumped into the wing very quickly. If you struggle to disconnect at all, you are likely to shoot towards the surface, ascending too fast and breaking decompression ceilings. This is why it's good to develop muscle memory beyond a simple disconnect. Of course, if you have a slight leak into your wing, it's easier to disconnect, abort the dive and use oral inflation as needed.
unnecessary workload with dsmb...that's why you shouldn't dive doubles in a neoprene wetsuit in the first place. not to speak of decompression dives. utter stupidity.
Hi Andrew, thanks for your comment. The first thing I want to say is that I don't think it's necessary to use that sort of language to get a point across. Aside from that, have you done much technical diving in tropical destinations? In places where outside temperatures are around or above 30 C and sea temperatures even at depth can hover around 28-30 C, many technical divers opt for wetsuits over drysuits to avoid overheating. (Yes, there are other ways to mitigate those risks, but using a wetsuit is one of them.) Which then leaves you with options including a dual bladder (this adds potential additional failure points as well as backing up your buoyancy control device) or a liftbag / DSMB. Of course, you could deploy the DSMB all the way to the surface and just hang from it. Personally, I don't like the strain on my shoulders and elbows over a long period. All of those add to the diver's mental and/or physical workload.
