I am an AOW diver and want to ask you experienced vets a question. I will be going back to Thailand in June. I am thinking that if I do some snorkeling that I can practice some diving skills. For example, mask clearing, bouyancy, etc. I know it is limited but I have had the most problems with bouyancy and masks. I have purchased a good fitting TUSA Platinum and want to play with it as well as practice bouyancy just by exhaling and expanding air in chest. Obviously snorkeling is much cheaper than diving and I can do it from the beach. Does this sound worthwhile to you, or do you think that practicing these skills without the weight etc may be a wasted effort? Any other skills that can be practiced in a snorkeling environment?
