Maintaining neutral buoyancy helps you dive safely when exploring the ocean’s depths. Wearing a buoyancy compensator device (BCD) helps you fine-tune your buoyancy underwater so you can float on the surface or drift effortlessly mid-water to allow you to observe the scenery. Scuba BCDs also make it easier for you to float so you can rest on the surface or swim to dive sites while carrying your equipment.

Gain More Control Underwater with a Scuba BCD

A scuba buoyancy compensator is a vest-like fitted jacket that connects to your scuba tank through a hose. This piece of equipment contains an inflatable air bladder that helps you maintain proper air buoyancy whether you’re on the surface or beneath the water.

A BCD scuba device has air pockets that you can inflate and deflate with the push of a button to control your depth in the water. Do this slowly and by letting out small amounts of air each time. Dumping too much air into your BCD could result in negative buoyancy, causing you to descend to the bottom.

BCDs can be broken down into three types. The jacket-style BCD slips on like a vest and inflates the front, back, and side of your body. The back-inflate BCD features an air bladder on the back so you can position yourself better horizontally underwater. Hybrid bladder BCDs are designed to help you float and dive comfortably in horizontal and vertical positions.

To choose the right BCD for you, keep it fully inflated and test whether it still fits comfortably. Check if the inflator hose is compatible with your dive regulator, then narrow down your choice based on style and personal preference.

Scuba.com has an extensive line-up of scuba BCDs for sale. We offer products for men, women, and children, with lift capacities ranging from 15-30 lbs to over 50 lbs. Shop with us today to find a BCD that suits your diving needs.

Buoyancy Compensator FAQ

What is a Scuba Buoyancy Compensator (BC)? A scuba buoyancy compensator is a device that helps divers control their buoyancy underwater. It allows divers to adjust their buoyancy level by adding or releasing air from the BC.
What are the different types of BCs? There are two main types of BCs: back-inflate and jacket-style. Back-inflate BCs have an air bladder that sits on the diver's back and provides buoyancy, while jacket-style BCs have an air bladder that wraps around the chest and provides buoyancy.
What should I consider when buying a BC? When buying a BC, consider factors such as the type of diving you plan to do, your body type, and your comfort and convenience preferences. It is also important to consider the weight and size of the BC, as well as the materials used in its construction.
How do I adjust my BC for different diving conditions? Your BC should have a series of dump valves and inflator buttons that allow you to adjust the amount of air in the BC. To adjust for different diving conditions, you will need to release air from the BC to become negatively buoyant, or add air to the BC to become positively buoyant.
How often should I have my BC serviced? It is recommended to have your BC serviced every 12-24 months, depending on how frequently you dive. Regular servicing helps to ensure that your BC is in good working condition and reduces the risk of failure during a dive.
How do I clean and maintain my BC? To clean and maintain your BC, follow the manufacturer's recommendations and guidelines. This may include washing the BC with fresh water after each dive, checking the air bladders for leaks, and regularly checking the hoses and connections.
