How do you use a BCD inflator?

How do you use a BCD inflator?

To orally inflate the BCD:

1. Take a breath from your regulator, and remove it from your mouth.
2. Place the power inflator’s mouthpiece in your mouth.
3. Press the deflate/oral inflator button, and exhale into the power inflator.
4. Replace and clear the 2nd stage, and continue the process until you are neutrally buoyant.

Why is the dump valve a very important item on the BCD?

Dump valves are important safety features and allow you to adjust the air in your BCD quickly. These valves allow air to expelled form the bottom of the jacket when the diver is swimming in the more natural horizontal orientation underwater.

How does a BCD work?

The buoyancy compensation devices (BCD), are the devices that give a scuba diver control with their buoyancy during a scuba dive. Basically the BCD allows the diver to inflate or deflate the device of air, allowing the diver to sink or rise when in the water.

What is the easiest way to deflate your BCD while ascending?

Using your left hand, grasp the bottom of the BC hose and raise it straight up. Press and hold the deflate button located on the end of the hose until a sufficient amount of air is vented from the BC (Photo 2).

How much buoyancy do I need in a BCD?

With 500 psi at 15 feet, if you vent all the air from your BCD, you should be very close to neutrally buoyant, rising slowly as you inhale, sink slowly as you exhale. If not, adjust your weight afterward — but if you’ve followed the other steps, you should be very close and fine adjustments should do it.

Why do you always hold the inflator hose above your head to release air when descending?

You do this by blowing into the hose while holding down the deflate button (which opens the valve to allow air in/out). Before you jump in the water you always make sure your BCD is partially inflated so that you can float on the surface.

What is the main reason to wear a BCD?

The main reason why divers wear BCDs is to help them to maintain neutral buoyancy. The importance of neutral buoyancy in scuba diving can not be understated as been neutral buoyancy, the diver will use less air and energy.

Are there sharks in Dean’s Blue Hole?

There is more to see in the area than just a beautiful hole in the ocean floor. The depth of Dean’s Blue Hole makes it a popular location for free divers. Larger denizens of the oceans, such as dolphins and sharks, have been known to enjoy the waters of Long Island. Sea turtles make appearances as well.
