If you had a choice on dives 50+metres would you use cylinders or a bail out breather ? Have never used a Bob or even seen one but am thinking one might be lighter than stages .This is for wreck dives in open ocean not caves
IMHO When youll be as easy and confident with your BOB alone as with your main one, then you can imagine to stay alive and going back home with one of your Rebreather flooded ( for ex ).
I play that game on cave diving because its necessary and because relatively less buoyancy problem.
I Dont imagine to do that in the see for shallower than 120 m.
And I dont want to imagine the number of wasted test dives in seawater before being safe

.
Now that Im easy

with that (in cave only ), Im very pleased to dive only one Rebreather with OC bailout and only a BOB staged somewhere.
