Your reserve tanks is filled while you are in the water using the other tank so there is always a fresh tank available. Getting in the water is simply a giant stride off of the back of the boat. Staff is available for assistance and gear pass up. The only exception to this schedule is on Tuesday when we dive the Blue Hole. The night dive is done at the same sight as the afternoon dive so that you will be familiar with the terrain under water.
All diving is done via computer.
Rentals are available if you don't have one. In general the diving was excellent. Virtually all dive sites have walls. Most walls go down thousands of feet. There are swim throughs and coral heads on every dive site.
