I totally agree with tstormdiver as to the mask. I'd like to add something on a snorkel. I am not a fan of the water-seal-float snorkels. Those are the ones with a floating ball or other contraption at the top of the snorkel- more trouble than they are worth, and they are pretty pricey. Get a snorkel with three important features: 1) a flexible portion of the "tube" near the mouth piece, and 2) a purge feature at the bottom of the mouth piece, and 3) a decent diameter tube. You should be able to stick you index finger in the tube. Should run you about $30.00. Also, get a soft rubber snorkel keeper that looks like the number 8 and use it instead of the keeper that comes with the snorkel. Most other snorkel keepers will have a tendency to become disconnected, and you don't want to lose you new snorkel! BTW, I have almost 100 dives, and I still snorkel a bunch on nearly every dive trip to warm water venues.
