Diving for the Beginner
All equipment can be hired for USD$5 per day on board your live-aboard safari boat. Below is a brief guide of the basic equipment.
Wetsuit
The purpose of a wetsuit is twofold, to keep you warm whilst underwater, and to protect you from marine life that may sting you. A full suit will keep you warmer at depth and give you more protection, but shorties are acceptable. The most suitable thickness required for these waters is 3 mm (though 5mm gives added warmth and may be beneficial if you are doing more than 2 dives per day).
BCDs
BCDs (buoyancy control devices) are inflatable vests that can be inflated or deflated to alter your buoyancy under water.

Dive watch or computer
You must have a watch that is waterproof to at least 200m, they are cheap but essential, and you cannot dive without one. Dive computers have the added advantage of logging your depth, giving you bottom time and decompression status, amongst other things.
