How to Use an Air Tank in Scuba Diving

Video Transcript

"This is how we would use different scuba tanks in scuba diving. There's actually multiple different cylinders that we can actually use when we go diving. This one, for example, is a small one we might actually use with, when using a dry suit. We actually fill this one with argon, and that actually keeps our body a lot warmer when we're doing cold water diving. This is a very standard cylinder that we use in most recreational diving. These are eighty cubic foot cylinders, here. And this one happens to be a fifty cubic foot cylinder, but we use eighty cubic foot cylinders as our primary scuba cylinder when we go diving. We might use something like this, if we were actually going to go...and do decompression diving. This one happens to be a fifty percent nitrox mix. And what nitrox means is you've actually bumped up the oxygen content of the air to be fifty percent. And we could use this as a decompression cylinder when we go diving. This is a standard nitrox cylinder, and this one happens to have thirty two percent nitrox mix in it, and we use this in any kind of recreational diving. So, when we go diving, we could use multiple different cylinders depending on what our purpose is."
