I am in the midst of my tech diving classes. My instructor teaches IANTD and DSAT. I have been diving a BP/W for the last 85 dives or so and doubles for most of my last 40 dives. I read the DIR Fundamentals book and geared my configuration towads this mentality. One of the discussions with my instructor, as well as a mentor of mine, is that in the ocean, with a wetsuit, you need a dual bladder wing. Based on my configuration and original thoughts, I felt that a bag was my backup redundancy, however I have started rethinking various scenarios and I am no longer sure. If I get a hole in my BC (not likely, but hypothetical), and am still negative due to gas, sure, I can blow a bag and/or kick the rig up, dependant upon required deco. The bag gives me plenty of bouyancy for hanging with deco, but what about once I get to the surface? If I were blown off a wreck, the boat's protocol is to stay with the diver(s) on the wreck. If I get done with my deco, and come up, and am in heavy waves, then what is a bag really going to do for me? A closed circuit bag, as sold by Halcyon, would provide a decent object to hang onto, but my current open circuit would not. Obviously I would need to keep my head above water, and it wouldn't take a lot of energy to kick up a little to stay above while on the surface, but if I was out for an hour, this might become too tiring to do depending on the environment. This may be a bit far-fetched, but I like to think outside the box.
Is a redundant bladder wing that important in the wetsuit / doubles scenario, or am I thinking too much? I mainly cold water dive with a drysuit and double 95s, and I have had to use my drysuit as redundant bouyancy before at the surface before. It worked great. My reason for asking is, I will be in my drysuit to finish tech, but we are discussing going to FL to do Trimix, lending to the possibility of doing it in a wetsuit. Most likely I will put some thin undergarments on and dive my drysuit because I trust it to back me up. If I should choose a wetsuit, I believe I may need to rethink my configuration
Oh, and before someone says, look it up, it has been discussed before, I realize this, and did a search first. I found several threads say they would blow a bag and use that as redundant bouyancy or swim the rig up. The part that is missing is, once you get to the surface, how are you going to stay up? I hope my questions make sense. My brain has been going a million miles an hour since my Advanced EANx class.
Thanks
