I use a snorkel when ocean diving in current where there might be rough seas and I could get separated from the boat.
If I get separated from the boat, the snorkel allows me to keep my face in the water in order to watch for sharks should my back gas be low. I am better off watching for sharks than scanning the horizon in order to say, signal for help. Besides, the rescue crews will likely spot the snorkel as well as they would a signal mirror, arm, fin, light or SMB waved at them.
In rough seas, in the odd chance that my entire body is not picked up on the crest of a wave, the 2 inches of snorkel sticking above my head won't get inundated with the deluge.
In a current.. I guess I could use the snorkel as a paddle or boat motor .
Definitely worth the hassle of it breaking the mask seal, getting snagged on lines, interference with donation to an OOG diver and crossing it with the BC inflator hose.
