Nemrod:I am a long time user of back inflation BC units, it is much easier and much faster for me to swim on my back and have done so from and to shore many times.
I only use a snorkel when forced to by the snorkel police and then I always tend to loose it somehow--darn--wear did that darn thing get off to? I see no purpose in a snorkel, I eaither stay on the regulator or I partially inflate my wing, roll on to my back and in that position I am like a motorboat, much faster, more comfortable, easier to take directional bearings and no air restriction breathing through some silly tube, no funky "nucleor cooling tower" dragging along in the water. I have made numerosu surface swims to and from dive sites as much as a mile in legth that way and never regretted having no stupid snorkel.
Snorkel with scuba?--no thanks--sometimes not even when free diving either. N
A back inflate does make a snorkel unnecessary. Even when I'm forced to wear a snorkel, I don't use it. I swim on my back. It is faster. I'll have to remember to "lose" my snorkel. Do you lose it before or after you get in the water?
