A Buoyancy Control Device (BCD) is one of the most important pieces of scuba equipment you will own. A good BCD allows a scuba diver to float comfortably on the waters surface in a face-up position and facilitates precise, easy changes in your underwater body position. A good BCD will also conform securely to the diver's body to minimize underwater drag and swimming effort. At TommyDSports, we provide a selection of buoyancy control devices to meet the needs of every diver. Our BCD's will provide a comfortable, nonrestrictive fit around the shoulders and waist to enhance your scuba diving experience.
