breathing

This posting in fact addresses two interlinked questions: Is there scientific evidence that the limit for breathing gas densities at depth (commonly 6.2 g/l) is the same for OC and CC diving? Is the work of breathing (WOB) the predominant factor that sets this limit? Background of my...

Hello, Im looking for an article, I think it was by SSI,SDI, or NAUI. It pertained to a frequent diver requiring less weight as you rack up your dive numbers (while using the same gear) because your natural respiration is smaller since you regularly dive and your body has become used to...

I know some/many of you may have seen this type of talk/demo before in your training...but this is a vid I made this year for our divers to reinforce proper trim training for open water/advanced students...Hope this helps someone! In this video, we explain/demonstrate the how to achieve and...

Hey guys, I'm new to diving and I was out today diving up and down the beach on the naval Air Station I'm stationed at, and I was about 5 feet under looking for shells for my wife. I bumped my secondary regulator and air started blasting out of it. I went from 2500 psi to to just under 1800 psi...
