In your Sept. 19 story "In Hot Water," you have again succeeded in perpetuating the myth of the use of "oxygen" tanks for scuba diving.
The constant incorrect reference by the media to scuba divers' "oxygen" tanks has created an ongoing public misconception that scuba divers breathe pure oxygen when diving. I am surprised that you are so ignorant or purposely are trying to maintain this myth.
The use of pure oxygen for breathing during diving is extremely dangerous and will result in probable death from oxygen poisoning if attempted at depths greater than 33 feet.
All sport type diving activities utilize compressed air for breathing. Please be aware of the public hazard that you are creating by the constant incorrect use of "oxygen" tanks or the breathing of "oxygen" when referring to news items about diving or scuba divers.
