In SASY, no actual snorkel is attached to the mask. I do not intend to strongly defend the whole concept; it may fly & may fail for reasons mentioned above. What makes the system different from regular snorkelling is that kids can't dive below the surface, they get used to using the equipment that a certified diver uses thus preparing them to think in terms of checking a pressure guage & assembling gear and it looks more "grown-up." Surely, there is much more cost involved than for a simple snorkel. But (at least with the systems I have seen), the floatation elements are removeable & weights can be put in the pockets if the child becomes ready for scuba training. I am interested to hear the experience of those who have observed the kids learning both approaches. What some kids find disappointing is that they CAN'T dive down on SASY whereas they can learn some skindiving with a regular snorkel. What are your young students saying? How do the parents regard this as a way for kids to transition into the sport?
