- You should check your buoyancy when (check all that apply) 1. your change your gear 2. when you go from fresh to salt water (or vice versa) 3. when you're not been diving in a while 1, 2, 3
- When conducting a buoyancy check your BCD should - be empty - have a small puff of air in it - have enough air to float you at eye level be empty
- For Peak Performance Buoyancy, you need to account for the air you use during a dive - regardless of cylinder type - when using steel cylinders - when using aluminium cylinders - only if you're not using a BCD regardless of cylinder type
- For Peak Performance Buoyancy, which of the following are variables that you should adjust for using your BDC (check all that apply) 1. amount of weight worn 2. air used from cylinder 3. buoyancy lost due to suit compression during descent 2, 3, 4
- You should adjust your buoyancy with your BCD (check all that apply) 1. to float comfortably on the surface 2. to begin an ascent 3. to compensate for buoyancy changes as you change depth 1, 3
- When diving with most dry suits, you donot normally use your BCD except to float at the surface - True - False True
- You use breath control to fine-tune your buoyancy by (check all that apply) 1. holding your breath as needed 2. breathing with somewhat full or somewhat empty lungs as needed 3. timing your breaths to help regulate your buoyancy 2, 3
- You normally distribute your weight so - you tend to roll face up - you're horizontal for swimming - your feet tend to rise - your feet tend to sink you're horizontal for swimming
- Reasons for streamlining include that it (check all that apply) 1. saves energy 2. minimize damage to environment 3. makes you more comfortable 1, 2, 3
- When you're streamlined, which of the following may drag or protrude away from you, even though secure (check all that apply) 1. your SPG 2. your alternate air source 3. your BCD inflator 4. nothing 4
- To use visualization to improve your performance, you mentally rehearse and see yourself preforming a skill - correctly as you would like to do it - incorrectly so you see the mistake to avoid correctly as you would like to do it
- For best results, visualize (check all that apply) 1. during the dive 2. after the dive 3. before the dive 1, 2, 3
- Benefits of physical fitness in Peak Performance Buoyancy include (check all that apply) 1. it's easier to maintain breath control 2. you need less weight 3. you have better streamlining 4. you wear a larger exposure suit 1, 2, 3
