Experienced SCUBA divers are most likely already familiar with the buoyancy control device, which is also known simply as a BCD. This particular piece of equipment utilizes an inflatable air bladder that enables divers to maintain proper buoyancy whether they are on the surface or far beneath the water. There are several types of BCD styles available, and each diver should choose the best one for his or her needs.
Jacket-Style BCD
This is the most popular choice among recreational divers due to its wonderful stability regardless of the diver’s position in the water. This style provides a basic jacket design with a bladder that wraps completely around the diver, and it inflates in front, back, and on both sides of the diver. Divers who choose a jacket-style BCD can expect extreme comfort, pockets for storing needed items, and pouches for weights that can replace the need for a traditional weight belt.
Back-Inflate BCD
Equipped with only an air bladder on the back area, the back-inflate BCD leaves the diver’s chest area completely unencumbered. This drastically improves the diver’s ability to become better positioned horizontally in the water, and that reduces water resistance, minimizes the workload, and allows the diver to enjoy their air supply for a longer period of time. This style is sometimes weight integrated, eliminating the need for a separate weight belt.
Hybrid BCD
The unique hybrid air bladder design offers the best of both worlds to recreational divers. Expect a relaxed and comfortable dive with the ability to easily maintain a flat horizontal diving position or a vertical position while on the surface or kneeling on the bottom.
Divers who are unsure of which BCD style may be best for them should visit a dive shop or ask their diving instructor for some sound advice. Divers who make sure they utilize the proper equipment during each dive have the greatest chance of enjoying safe diving adventures for many years to come.
