Once you start getting to technical depths you operate under the assumption that you are alone, even when diving with a buddy.

I know some french federation divers who will tape their hands to their hand power inflator to avoid confusion when experience narcosis at depth.

At first I thought it was a goofy idea, but after experiencing debilitating narcosis at 60m I had second thoughts about it.

No you really don't. I do a lot of technical diving and depend on my buddies for safety. The key is to select reliable buddies who have been properly trained.

And taping your hand to your power inflator is just too stupid for words. Put some helium in the mix.
