Question to drysuit divers:
If you are diving solo and got inverted due to the ankle weight fell off or air got malditributed to your ankles, what would you do to fix it?
When you do a drysuit class they teach you to do a roll. Something like this:
Personally I found that with more experience you can feel better when you start being floaty in the legs and deal with it before it is uncontrollable. When I started, I didn’t notice as much the changes of trim/buoyancy and reacted often too late. (If you are only slightly floaty, you just need to go a bit heads up and extend your legs to bring back the gas into the upper body)
Also, from my experience, if you use the BCD for buoyancy instead of the drysuit, the air bubble (in the suit) is much smaller so it is much less of an issue, because it won’t get as floaty.
