And for a BASIC and ENTRY level instruction, HELL YES....... And when your going to quote something, don't quote just a small part of it, quote the whole thing.. Here I'll do if for ya, and re read part of what is in the open water manual!! Oxygen Because you need oxygen to live it may seem strange to learn that it can be toxic in high amounts and pressures. In fact if you were to fill your scuba tank with prue oxygen instad of compressed air, you could experience oxygen problems in very shallow water. This is why you should have you tanks filled with anything except compressed air. (which hopefully will be rewritten soon to cover the new gas mixes out there) The oxygen in compressed air CAN also BE TOXIC, but not untill you descend well past the recommended maximum limit for recreational diving, which is 100 feet. To prevent oxygen toxicity, never fill your tank with pure oxygen and never exceed the mazimum recommended recreational depth limit. And then PADI goes on to Nitrogen Narcosis, saying "while breathing air at depths approaching 100 feet, you can experience an effect called nitrogen narcosis." They go on to tell the dangers, effects, what to expect, and how to deal with it. And finially they go in to a 3 page write up about decompression sickness. This has worked in the past, and it gives the entry level diver a basic Idea... Jeff -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
