Hello, I am not certified as of yet. I have completed my SSI academic training, and looking forward to the pool portion here in a few days. My wife and I both are going to become certified. As my user name implies, I got a late start in life. I am almost 60 YO. My wife and I have done a lot of snorkeling, and decided to take it to the next step. The local dive shop had a "Try Scuba" event, went for it, and decided we wanted to give it a go. Considering I know absolutely nothing about diving (except what i have learned in the on-line class), looking forward to all the knowledge I am sure is floating around this site. Brian
