In 30ft of water, almost 90mins, probably could have gone longer, but hubby had to surface when he hit 700 PSI so I had to surface too, i still had around 1100 PSI left :-P

Good answer, just show how good women are at breathing rates. In Mexico on a drift dive useing 100 c.f. Tanks. We were able to get 120 min. We started deep and drifted to shallow water. After two hours under water I was cold and ready to get out we had no idea the dive master was going to take us on this long dive. A really fun dive.

A little over an hour on a multi level dive that started around 60ft and moved up to around 30. I was using an 80cf al cylinder.
