Remember the days back before the valve manufacturers decided to go to the "captured o-ring" concept? It was supposed to allow higher air pressures for the tanks of the future.....what a joke. Those old fat o-rings would often last two years.....in a rental tank! Now you're lucky to get 3 or 4 dives out of one. If you want a true captured o-ring design that is adequate for *much* higher pressures, to my way of thinking there is only one way to go: the DIN connector. The old AGA Divators and Poseidon Cyclons could easily handle 4500 psi without you worrying about bumping them on a rock.

If you check a map thats about half way down Florida on the west coast. Major cities would be Clearwater, Tampa, and ST. Petersburg. There is a great effort for artificial reef building going on by our local county gov't. While there are some nice natural reefs and there are some wrecks in 80-130 feet. I think the east coast (West Palm Beach, Ft Lauderdale) has better diving and the boat trips are much less time consuming. While of course the best diving was in The Cayman Islands. --- OLX 2.1 TD Mental Floss prevents Moral Decay. --- InterMail+GE/2+PCB/2 * Origin: The 128th Parallel Seminole,Fl 28.8k 813/397-1339 (1:3603/210) --------------- FIDO MESSAGE AREA==> TOPIC: 186 SCUBA Ref: DEU00006 Date: 10/24/96 From: STAN DEAN Time: 10:04am \/To: DAVID BATTESTELLA (Read 2 times) Subj: Nitrox DB> -=> Quoting Stan Dean to David Cheshin <=- DB> SD> I myself have not taken the NITROX course but from what I understand DB> SD> there is something like a definate depth of 135 ft as oxygen toxicity DB> SD> will result.

I think every recreational diver should aim for the Rescue certification by the time he has logged 50-100 dives. It's a logical extension of the training that starts with OW, and a great skill and confidence builder. Plus, Rescue was a lot of fun! Get the idea out of your head that deep diving is anything but...well...deep. I know, this is a Holy Grail for novice divers, but you'll get over it. The only difference is that you guzzle air like crazy and you have to get out of the water too soon--unless you get narced, in which case you become a danger to yourself and your buddy. There's nothing intrinsically magical about deep diving, especially in fresh water, where it's cold and dark. In the ocean, it's usually clear and only a little darker than lesser depths, but unless there's something special to see, there's really no point in blowing off all that air just to say you did it. --- MacWoof 1.5.3 * Origin: St. Louis, USA / http://www.inlink.com/~creative/ (1:100/514.2) --------------- FIDO MESSAGE AREA==> TOPIC: 186 SCUBA Ref: DEW00001 Date: 10/26/96 From: DEREK A.

How can you stop a 12-14 year old from diving without a Adult certified diver esant? Legally you don't even need a license to dive. It would be stupid to dive without a certification, and of course I myself would never recommend diving without certification, in fact we as responsible certified divers all know, one would more than likely hurt themselves or even kill themselves without proper training, but the reality is that if you were wealthy enough to buy all the gear brand new, and your own air filling station, and you were stupid enough to go without certification, you could in reality go diving today without a C-card and no one could do anything about it. So in my opinion a "Junior C-card" is also bogus. Either you are certified or your not. Why would an adult with a c-card make any difference to a diver regardless of age? BTW just out of curiosity, when was the last time you were asked for your C-card anywhere in the world before they would fill your tanks? I myself have dove all over the world and have been diving regularly for 15years, and have Never, not even once been asked to show my C-card before they would fill my tanks. They always check for current Hydro and Vis, but never ask to show my C-card. In my opinion, Air filling stations should be required to ask for proof of certification before filling any tanks. They always talk about not being able to get tanks filled in the PADI course, and any good instructor will instill this upon their students, but in reality the c-card is rarely asked for, and in my case has never been asked for.

Although they still use the DIN adaptors quite frequently. It is largely European, but now again here in North America with Steel High pressure tanks we are seeing tank valves that require DIN ptors. -=Derek=- --- RA - PORTAL - GECHO - ALLFIX - TNP - GOLDED......KOOL! * Origin: Maria & Derek's BBS 33.6K, Vancouver,BC {604}420-4860 (1:153/7041)
