My thought exactly. I am trying to envision this. Can you help? I am going to describe some of what I see happening in an intro to tech class, and perhaps you can tell me how it is done differently there. I am really interested because I am supposed to go there soon and might welcome the opportunity to do some practice.
In our tech classes, we wear dry suits with pockets. The dry suits are crammed with things like SMB's and spools. These are removed and deployed as part of the class.
We wear heavy steel doubles, which weigh so much that there is often no need for additional ditchable weight, even when diving dry. The dry suit is a critical means of redundant buoyancy in case of a wing failure.
I am obviously trying to envision diving heavy steel doubles with no redundant buoyancy and without a clear means of carrying bags and all.
I was wearing double steel 104's. No additional weight. No dry suit. Water temp is low to mid 90's. Dry suit would have been way too hot. If we had scheduled at Blue Lakes south of Wendover, we would have taken our dry suits. Primary bouyancy is the wing. Reduncant bouyancy is the lift bag. Lift bags and reels were in tote bags snapped onto harness D rings. We did remove lift bags and reels and deploy them.
Or maybe I'm not understanding your question.
