Good call. You might want to consider clipping a spare one on the 15' stage bottle the boat deploys. Then if you lose it, you can recover that warm and fuzzy feeling before your safety stop begins...That's why I keep my snorkel on one of those rotating clips so that it just swings out of the way. Seamless ... I love my snorkel. When I go in a wreck though and I have to take it off and leave it clipped to the line outside the wreck I just feel naked. There's nothing like returning to my snorkel after a nice wreck penetration. Once I put it back on I can finally relax.
