BIlly, Whats really absurd is that he is blathering about deep stops on a no deco profile. Hello, Mom? If its really a no deco dive, just go up.

Doing a 2 minute stop at 1/2 the maz depth and a 3 min. stop at 15, I find it annoying not to have a seconds display, because I end up having to round up, and might do a 2.59 minute stop. It's just boring, and since I want to be setup with 2 timing devices anyway, I just made sure the second one has seconds on it. It's not a question of timing stuff to the second, it's a question of getting an idea of where you are in the minute, beginning or end. >> >> Other than that I agree with what you say. > > > 2.59 instead of 2.00?
