In recreational scuba diving there is a laundry list of available equipment to fit nearly every underwater need. One of the most important pieces of equipment a recreational diver uses is the BCD or buoyancy control device. The BCD is an adjustable inflation vest worn by a diver to increase or decrease their buoyancy during a dive. The BCD is hooked to the regulator or “Octopus” which serves as a junction point for air accessories. The BCD usually comes complete with safety features like an emergency dump valve. Safety features like these help to prevent BCD malfunctions, such as runaway accents, by allowing the diver to release the air out of the vest. Attached to the regulator along with the BCD are air pressure gauges and two breathing apparatuses. One breathing apparatus is used for normal breathing function and the other is set in a known location in the case of an emergency or disorientation. Recreational divers also have a choice between wearing a neoprene wet suit, which keeps a diver warm by retaining a layer of water next to the body, or dry suits that use a layer of air for buoy...

- 33 feet up, looking down at the water, trying to determine if this trick will make or break a diver from the rest of his or her career is a heart pounding experience. He jumps, spins, flips, and then hurdles 62 miles per hour toward the unforgiving water head first. The loud splash the diver makes as he enters the water perfect.

As diving had began to evolve from just a simple “swan dive” to a 109 B (Forward 4 and ½ somersaults, pike). Not only has the difficulty tremendously increased in this sport, but it has been one of the most watched sports in the Olympics games since it took off in 1904....
