I think you googled this and hit up Force-E's page. lolz.
Do you live in Florida or just make it a frequent ticker you follow on SCUBA lessons?
He might but from personal experience when you get into scuba you get excited about it and go all gung ho into it. I had wireless air computer till I went nitrox and then I went from air aluminum tanks to steel tanks for nitrox. Not that you need to do that its just that Nitrox allows for more bottom time so on air I would run into decompression before I ran out but with Nitrox in aluminum tanks I ran out of nitrox before I needed to decompress so then I got Steel tanks to hold more air/nitrox. Its all about bottom time in scuba.
My partner and I had neverlost (like gps) so we could find each other and the down line. Jersey can have a lot of soot water and you can lose each other quick it worked.
Then I had a teacher that was getting me excited about technical diving - trimix and penetration to dive the andrea doria (240ft) carrying 6 steel tanks over loaded you take to the bottom in case the boat isnt there when you return. I met my wife around this time and my gears changed. He recovered something like 100 pieces of china from that wreck. Also pulled a dead diver off it too.
You can see how this gets carried away quickly.
BTW I was certified in Florida, Moved to NJ and did most diving there, and now Im in NC looking to get back into it.
