Ever been out diving with friends and the conditions are fantastic, yet you can't get back in the water because there are not two tanks available with enough air for a buddy team to get any descent bottom time? You got one full tank and another just under half full. If only you could equalize the two cylinders, so you have two tanks 3/4 full!
