Well thanks to Stu and Steve i am now past my first cold water diving experience. The dive(s) were a lot of fun and i was surprised at how nice the vis. was. Steve provided quite the show trying to catch that lobster. I give him an A+++ for effort. Another 400 psi in the tank and he probably would have got it.
Sunday my girlfriend and I dove at old garden beach with the folks from PGDive and had two more great dives. My girlfriend experienced her (and my) first underwater problem. Her regulator was free flowing at the end of our second dive in 15-20 feet of water. She made an attempt to fix it but being rental gear she wasn't extremely familiar with the gear. We surfaced and by this point she was almost completely out of air. We determined that she must have hit the adjustment on the second stage while clearing her mask and not realized it and after doing this several times the reg. was free flowing.
Lessons learned.....stay calm (it's only air flowing out...no big deal), get the free flowing regulator away from you so you can see, switch to backup, surface and investigate the problem above water.
I think we'll be getting her some of her own equipment asap. Although PGDive has some of the best rental equipment i've seen, having your own gear that you are familiar with is the way to go.
Hope to dive with you guys soon,
John
