My question came from another board but I'm looking for a more specific recommendation.
How do you determine a safe ascent rate if your computer and /or timer or any other such gadgets fails? I was taught ascend with your smallest bubbles from each exhalation. That was supposed to give you close to a 60'/min ascent rate. Nowadays agencies are teaching or at least recommending slower ascent rates.
