I am sorry but I simply don't understand how anyone can say that generally a unit is safer than OC.
Providing you have properly serviced regs, what is there to go wrong on an OC dive between 10 and 85m (Flying Enterprise sort of depth)?
Have a read of some of Dr. Mike's posts. He'd be dead if he was on OC!
The big advantage a rebreather gives you is time. Lost in a wreck? Tangled in line? I've got several hours to get myself out, instead of 10 minutes. Ok, I'll have a few hours of deco to do but I'll be alive.
Rebreathers do have additional risks. CO2 scares the crap out of me. But with OC the gauge drops on every breath.
But that's just my judgement of the risks. Yours may vary.
