Scuba Diving // 3 Facts, 1 Fake Fact


1 | Fact. A “safe limit” for recreational divers is ~40 metres. An Egyptian man, Ahmed Gabr, travelled 10x farther below the top of the Red Sea — basically the distance from CN Tower’s EdgeWalk to the ground. Took him 14 hours to come back up, too. He is very popular when friends lose their shades overboard while canoeing.

2 | Fact. Unless it’s filled with pure oxygen (which deep sea divers use), a tank of compressed air (for rec diving) would not explode in flames like in Jaws. However, picture a champagne cork hitting your eye around a force of 80 PSI. Now, can you envision that clocking you at around 3,000-4,000 PSI? No, you can’t, your head is gone. A standard (diving) cylinder of compressed air suddenly rocketed down the shark’s throat would be fast-tracked through its digestive system and out its tail fin. (Spielberg really did come up with a better… ending.)

3 | Fake fact. Well, the scuba part is far-fetched. Training Russian dolphins to carry bombs to detonate against hulls is normal, though.

4 | Fact. According to a book published by Fredericton’s Goose Lane Editions, Messrs. Alexander McAvity and James Elliot Elliott Eliot (sp?) patented an “oxygen reservoir for divers” to be carried on one’s back underwater. Imagine, two guys looking at the Saint John Harbour and saying, “Y’know what? I not only want to go into that stew of raw sewage but I’d like to have my head under it as long as possible.” Well, those two brilliant men patented their scuba device on March 4, 1839! #RenaissanceCity

“And if you turn your head and nose to your left just beyond the photo crop, you’ll actually need that scuba tank…” (See Saint John)
