Please notify us when you book a tour if you would l ike us to supply any of the following scuba gear for you. We are happy to do so at a reasonable price. Equipment
1. Air Tank 1. The air tank holds high-pressure breathing gas. Typically, each diver needs just one air tank. Contrary to common perception, the air tank does not hold pure oxygen; rather, i t is filled with compressed air that is about 21 percent oxygen and 79 percent nit rogen. 1. Examples: Aluminum, steel, pony 2. Buoyancy Compensator 1. The buoyancy compensator controls the overall buoyancy of the diver so t hat descending and ascending can be controlled. 1. Examples: Wings, stab jacket, life jacket 3. Regulator 1. A regulator controls the pressure of the breathing gas supplied to the d iver to make i t safe and comfortable to inhale. 1. Examples: Constant f low, twin-hose 4. Weights 1. Weights add just enough weight to help the diver descend rather than f loat. The r ight amount of weight will not cause the diver to sink. 1. Examples: Weight belt, integrated weight systems Atti re
