What Does it Mean? History? • SCUBA – Self Contained Underwater Breathing Aparatus • Long history dating back from 332 BC • Modern fins, mask and snorkel tubes were developed by fishermen from America, Russia, France and England in the 1920s and 1930s
History continued • Recreational SCUBA Diving began between 1942 - 1943, after Emile Gagnan and Captain Hacques –Yves Cousteau developed the self-contained “Aqua-Lung” and new regulator that was automatic. • Cousteau took many successful, experimental dives with his friends, wife and two sons, making this an experimental family trip and experience.
Mask- Device covering eyes and nose, allowing you to see underwater Fins – Device put on the feet to extend the kicking motion underwater. Equipment
BCD or BC – (Buoyancy compensator device) Device/jacket that controls buoyancy up or down Regulator – Device that delivers air to you on demand at reduced pressure Equipment continued
Pressure gauge – (SPG- Submersible Pressure Gauge) Device that tells diver how much air they have left Weights – Lead weights used to weigh down divers for depth decent Equipment continued
Snorkel – Device used to breath air close to or on the surface of the water Body suit – Warm temperature suit that protects the body against abrasions and stings Equipment continued
Wet suit – Insulated suit used to keep the body temperature in Dry suit – Used to keep the diver dry and warm in colder temperatures Equipment continued
