Rescue exercisesduring trsining has taught me that in practise, extremely difficult to do without putting yourself in danger. Anyone not using a BOV is pretty well not very "save-able" unless
1) victim is already pretty close to the surface
2) have a knowledge-able Rebreather buddy who can maybe regain conciousness of the victim (if he is at least wearing a neckstrap that prevents loss of mouthpeice).
3) A highly skilled Rebreather buddy simultaneously capable of
a) protecting the victims airway
b) managing 4 to 6 air cavities to control bouyancy
c) considers you sufficiently important to risk his/her
for you.
BOV's work good. Please get one (money very well spent).
