The idea being you can get resort type people "SNUBA" diving without the risk of DCS because of the depth limits imposed by the rig. I think the main target audience was people who were scared of the risks of scuba, but didn't enjoy the limited viewing time inherent in snorkeling. Kinda like a mix between the old hard-hat diver and the freedom of open-circuit scuba. The only time I ever performed the previously mentioned "kit-jumping" was in the bottom of a pool during Basic OW training. The goal was to increase self assurance underwater. We were strongly cautioned against surfacing, and repeatedly told to continue breathing. Lung-expansion was also a well versed topic by the time of this exercise. Not the sort of thing you would want to do while trying to look at the pretty fishes. Rob rhs9145@ri*.ed*
