The reason I asked about doff and don exercises is that yesterday, I decided to dive a new (to me) jacket BCD. I had bought it last winter, but had not dived it. I have been diving either my Para-Sea BC, which I invented, or a Dacor Nautilus CVS system. But I decided on the jacket BCD to evaluate it. I also decided to use one of my more advanced Dacor regulators, with a octopus, LP inflator and Cobra dive computer. Well, I was about fifteen minutes through my dive when I noticed a greater-than-normal pull on my primary regulator. What was happening?
I figured out that my steel 72 tank had become loose and out of its band. The only thing holding the tank was the regulator being snagged on the nylon tank retaining strap. So I had to do an in-water doff and don to get the thing back together. I found a place about 15 feet deep, took it off, got the tank back under the strap, made the strap tighter, and put it back on. It took a while, but I was able to do it.
If you haven’t figured it out, I was diving solo under a lifeguard station, with a dive flag and float. I had decided that surfacing probably wasn’t the best thing to do, as on the surface I’d have to deal with gravity. So I did it on the bottom. I also have a video of the process, and should have that available in a few days.
I felt good on two levels, first that this 75 year-old diver could still do an open water doff and don, and get out of the situation. Second, that the lifeguards were watching down at me, probably wondering why I was in one place for over 10 minutes (I’ll see how much time it took off the video).
