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. The diving in Belize is still pristine. There are many hard and soft corals, various sponges, etc. All of which are pristine and healthy. Diving the Blue Hole is on Tuesday.
