Sharing Your Alternate Air Source

Out of air sharing isn’t as complicated as it used to be.

These days if you happen to run out of air, which you shouldn’t as long as you pay attention to your pressure gauge, you can count on your buddy to have an alternate air source. No longer do divers need to rely on passing a reg back and forth. With an alternate air source, or octo, both divers can breathe off a single tank using individual regulators.
