1. How can you inflate your BCD? Orally inflating the BCD. With the air from the tank via the low-pres- sure hose. Both. 2. The first stage reduces the pressure of the gas from the tank to: An intermediate pressure. The ambient pressure. Does not reduce the pressure. 3. With the tank valve closed, try inhaling from the second stages, you should: Breathe easily. Can not breathe. Hard to breathe. 4. The underwater computer replaces: The depth gauge. The timing device. Both. 5. When should you begin to equalize? As soon as your head is underwater. As soon as you begin to feel pressure. Ears equalize themselves without any ac- tion. 6. All divers should carry a Surface Marker Buoy (SMB)? True. False.

1. Both. You can inflate your BCD orally or with the air from the tank via the low-pressure hose.<br />2. An intermediate pressure. The first stage of a BCD reduces the pressure of the gas from the tank to an intermediate pressure.<br />3. Hard to breathe. With the tank valve closed, trying to inhale from the second stage will be difficult.<br />4. Both. The underwater computer replaces the depth gauge and the timing device.<br />5. As soon as you begin to feel pressure. You should begin to equalize as soon as you begin to feel pressure.<br />6. True. All divers should carry a Surface Marker Buoy (SMB).
