I should - answer - stop, descend slightly, and allow trapped air to work its way out My buddy and I descend to 12 metres/40 feet. I would expect to use my air _____ at 6 metres/20 feet - answer - faster than The most efficient way to breathe dense air underwater is to breathe - answer - deeply and slowly Buoyancy - answer - a force that pushes an object in water upward Salt water causes more buoyancy than fresh water because it is _____ dense and weighs _____ - answer - more When I descend, my buoyancy tends to ________. When I ascend, it tends to _______ - answer - decrease, increase The three most important considerations in choosing scuba equipment are suitability, fit, and - answer - comfort The two basic fin styles are __________ fins - answer - adjustable and full-foot My primary considerations when choosing fins are fit and - answer - blade size BCD (buoyancy control device) - answer - holds your kit together and allows you to adjust buoyancy throughout the dive Regulator - answer - delivers breathing air at the surrounding pressure when you inhale and directs exhaled air into the air Cylinder - answer - holds the high-pressure breathing air supplied by your regulator during the dive Weight System - answer - holds lead weight to counteract the positive buoyancy of your body and some of your equipment, with a mechanism for dropping some or all the weight in an emergency The five components that make up a BCD include - answer - an inflatable bladder, a cylinder band and harness/jacket, an LPI (low-pressure inflator) mechanism, an overpressure/quick exhaust valves, and a weight system LPI mechanism - answer - inflates the BCD with air from my scuba cylinder Burst disk - answer - a safety device that relieves accidental overpressure by releasing air before reaching the pressure at which the cylinder would fail scuba cylinders require pressure testing _______ and visual inspection _________ - answer - every 2-5 years, annually The most important feature in my weight system is its - answer - quick release Trim means having the right _____ of weight - answer - distribution Failure to follow the most important rule in scuba diving can cause serious lung overexpansion injuries, which in turn can cause paralysis and death - answer - true An object that is neutrally bouyant in fresh water will _____ in salt water - answer - float Underwater objects appear - answer - larger and/or closer Sound travels about 4 times _____ in water than in air, making it difficult to determine its source - answer - faster To move efficiently as a diver, I should move - answer - slowly and steadily Trim is important for streamlining because - answer - poor trim raises or lowers my feet, causing drag Overexertion results from - answer - a prolonged increased effort Buddy Predive Safety Check - answer - Begin With Review And Friend BCD, Weight, Releases, Air, Final Check
