Do not go ice diving after a night shift and several cups of coffee. Bad combination that adds up to a bad experience.
(For those that use a snorkel) Make sure that you have switched from snorkel to reg before descending, because that first gulp at 5 feet sucks.
Make sure that if you need to push a button on you computer to turn it on, that you do so before you hit 70 feet (especially at Palancar Reef in Coz, which is at least a 130 foot dive and a computer is nice to have).
Redundancy is nice to have: computers and air and anything else that is important to the dive and is feasible in two or three.
I agree with Ber: any diver may call the dive at any time without question. No need to lose a diver; there's always another day to dive.
Remember your drysuit when diving Isle Royale in L. Superior. Doing it wet just really isn't an option.
I'm sure there are more floating in my head, but can not think of them at this time.
Cheers all
