those are my favorite ones also..used to do free dive spearfishing in Newport Rhode Island with the shotgun..snorkels have their place..if you dive of beach and cover alot of ground/distance from beach its a good idea to have one..off a boat if you go down a anchor line then up as we do on northeast wrecks really not needed..average rec diver in caribbean trip-probably good idea for most of them for they cannot navigate back to boat on the bottom..John C. Ratliff:Snorkels are pretty useful tools to have. They allow you to rest, face down on the surface. In the US Navy School for Underwater Swimmers, snorkels were not allowed (1967). They felt you needed to know how to cope without them. In the USAF, we sometimes carried snorkels in our dive-knife sheath (under the straps), so they would be available after parascuba jumps. I now always dive with a snorkel, by choice and not because someone told me to do it. I have a number of different types, and my two favorite ones are the ScubaPro Shotgun (from many years ago) and the USD Impulse. The other one I really like is a long-ago extinct Dacor flex snorkel (I have two of them, and like them with Scuba). You really don't appreciate snorkels until you have had a stomach cramp, or been on the surface in 15-20 foot waves waiting for a Coast Guard pickup for several hours (happened in the 1970s, and I wish the snorkel was still with me at the time).
