Gas management. Mostly the proper attitude of gas management. We were taught to leave 500-800 psi. in the tank, which basically resulted in people heading in the general direction of the boat early and at the end of the dives you had 6-8 people swimming around in the immidiate proximity of the boat trying to get that last bit of sightseeing in. If we'd just gone to the top we probably could have gotten another full dive in instead of sitting under the boat for 10 minutes so we didn't feel cheated.
