What is a Buoyancy Control Device (BCD)?

Posted by: sddiver96

sddiver96

When you go scuba diving it can be frustrating when, for instance, you visit a wreck and find yourself floating down to the sea bed. A shipwreck often sits on the sea bead floor but some of the more interesting spectacles and finds are discovered at the top of the wreck. This can be several feet above the sea bed.

Most divers find when they reach the top of the ship wreck they are automatically fighting to get back up to the top of the ship and using a great deal of energy in just staying buoyant in that position. This is where the buoyancy control device, or BCD comes in.
A buoyancy control device will keep you in position hovering in the spot you want to. No longer will you float up or down to the sea bed and miss lingering on those fascinating sites often seen on the ship deck and balcony.

This buoyancy control device is also needed like when observing schools of tropical fish that like to move around 12 to 15 above the sea bed. It is far more thrilling to observe the school face on rather than from below. Basking sharks are also better observed at eye level and not from several feet below them. A buoyancy control device is perfect for holding the diver in position to observe sharks that more often than not swim in the centre of the sea depth and only occasionally hover on the sea bed.
Your buoyancy control device will allow you to release air from an air bladder so you can float or hover at your own depth. The buoyancy control device is sometimes referred to as a buoyancy compensating device or BC jacket. A wings and harness style is becoming popular among scuba divers as an alternative to the BCD jacket style. The harness system uses a bladder that is trapped between the harness and the tank. This style is more often used where scuba divers are diving with twin cylinders. Many lately even come with secure pockets for your weights, so that a weight belt can be eliminated, although this method may take a little getting use to.


There are a number of features on a buoyancy control device jacket, including the adjustable band that allows you to swap out your tank(s) between diving sessions. A low pressure inflator is also fitted which allows you to release air or alternatively gain more air and inflate (to rise up in buoyancy). Another feature is the over pressure valve which lets air out of the buoyancy control device so it will not split the bladder when overinflated.
BCDs come in so many different styles and sizes so be sure to try a few different ones before investing in your own.
