Well welcome to Scubaboard!! You'll find lots of great information here, and lots of great people. And a few boneheads, probably....but the good information and people more than make up for it!theunraveler:Yeah I'm new to diving
Since you're new to the board, stop the the introduction section and say hi. Also check out your regional area. I've been a Kelp Diver/Rocky Mountain Oyster/Conch head and it's been great! Everywhere I have been I've met Scubaboarders for diving and socializing
As you take continuing ed, you'll learn about PP02 and why it becomes toxic at depth. I believe you hit the toxic range at 218 feet or something? (Don't ask me to do math..it's early) When you get a few dives under your belt, look into Nitrox. It's a safer way to dive and lets you enjoy more bottomtime. I took the ANDI CSU 2 class where you certify to dive mixes up to a 50% oxygen mix. Good luck!
