Peter Guy:HOWEVER, I think we ALL agree that the basic training of the "recreational" Scuba diver (OW and AOW) is just that -- VERY basic. While she and I disagree on this -- I believe (and apparently the stats support me) the basic recreational training is sufficient to teach people how to dive safely AS LONG AS they have supervision -- that is, the basic DM led group dive while on vacation. They don't have to think -- they don't have to plan -- they just follow the DM as part of the "trust me" philosophy and remember to breathe on the way up, stop for 3 minutes at 15 feet (or so) and be back on the boat with 500 PSI. (BTW, I think that is great for the industry and for those involved and I praise PADI/NAUI/etc. for opening this sport to the masses.)
With or without direct supervision ON the dive itself, I have seen many people whom wouldn't survive in many more challenging environments do just fine on a normal fun dive (ooh... look at the colorful fishies) to 60-70 FSW. Basic recreational training is adequate to keep the basic vacation diver enjoying a relatively safe sport. With or without a team mentality, or even without conquering buoyancy skills, someone with a simple PADI or NAUI OW card should be self sufficient to plan a no decompression dive using a dive planning chart (RDP) -
