My name is Pete, and I am new to diving. I just got certified in August of this year. Over the weekend I went to Gilboa Quarry in Ohio to dive, and it was really cool. I only had one problem toward the end of my first dive when I had a freak out moment, because in my head 800 psi was a small amount of air, not sure why. I am not sure if my freak out moment was because I was on edge before even going into the water, but I do not want it to happen again, because I did a big no no and shot up to the surface from 40 feet. I know that can be pretty bad when in deeper water, so I came to scubaboard in search of tips and advice. I am going to begin searching threads, but if anyone has any tips for calming your self under water, they will be greatly appreciated. Thanks in advance.
