Some of you may already know that scuba means self contained underwater breathing apparatus, and a few of you might even be part of the dive world’s equivalent of the mile high club, the 20 meter club. But for those unfamiliar with the ways of the scuba, well, it’s about to go down.

  1. Where's my 400ft squad even though it's not that deep but still is pretty deep I am just going to shut up

  2. some times its good to get a refresher of these simple facts even though a person like me who is a PADI divemaster has knowledge of this stuff lol

  3. I must say that I'm a huge The Office fan but this is the first time that I see the scene Creed talking about scuba ! huh !

  4. oxygen becomes toxic in 20 ft/6 m, oxygen and nitrogen in Air becomes narcotic in 100 ft/30 m. Get facts correct!

  5. Just as another commented that scuba tanks contain air not oxygen, the wetsuit is not full of "nitogen bubbles". It's just full of air, which is approximately 21% oxygen, 70% nitrogen and other inert gasses. Also, the oxygen level (in the air from the tank) does not become toxic at 100'; You're confusing nitrogen narcosis (which gradually increases with depth but is definitely noticeable as the diver aproaches 100'. But to say a diver will act "drunk" whenever he exceeds 100' is simply silly. However the oxygen level gets concentrated to a toxic level when the diver approaches 200' and can lead to black-outs, thus the need to displace some of the oxygen by introducing other gasses into the air mixture.

  6. we call it the 100ft club 😉 and yesh I'm a member. btw oxygen becomes toxic way deeper then 30m it's the nitrogen you breath that turns narcotic, ergo nitrogen narcosis. and trimix replaces the nitrogen with helium.

  7. There's a mistake at 3:25 when referring nitrogen narcosis; Oxygen doesn't begin to become toxic at 100 feet. I think he ment to say NITROGEN begins to be come NARCOTIC at 100 feet. The toxic depth of nitrogen is much deeper than 100 feet. Air or 21% Oxygen becomes toxic at 270ft or so. 100% Oxygen begins to become toxic at 25 feet or so. Your results may vary.

  8. as a Master Scuba Diver Instructor for the past 23 years your information is very close but not completely correct.

  9. I'm a divemaster, and just have to ask, the "20 meter club" is really a thing? It's so rudimentary that I can't see why people would keep track of that. 30 meters, 40 meters, sure, I guess, but 20? Anyone?
