Planning on buying some snorkel gear for our trip to Coz at the end of June. Is a "Dry" or "Semi-dry" snorkel better? Heard both sides. I'm wondering if I free dive down, will the buoyancy of the air in the snorkel tend to pull it from my mouth or is it even a problem to be concerned with?
Would anyone recommend SnorkelMart.com to purchase the gear?
