Re: How long can you hold your breath?

General rules can often times be way too general. 90 seconds is a pretty long time, and could easily lead to a blackout in many conditions for most people. Range of time to SWB can vary hugely depending on A) a persons physical conditioning, B) how well he prepared for the dive and C) how much he exerted themself during the dive, D) how deep he dove, E) other factors. I have done over a five minute static, but if i try to cruise along the bottom of a 40 ft area for over 60 seconds, there is a real good chance i'm going to samba or BO upon surfacing. I think its far more important to learn to read symptoms of hypoxia (best done in a FII or PFI course), than it is to go by number guidelines.
