Scuba BCD

Buoyancy Compensator - Master Your Buoyancy

The Buoyancy Compensator Device (aka: Scuba BC or Scuba BCD) is an essential part of a diver's life support package. The primary functions of a Scuba BCD are to control buoyancy and hold the tank during diving. BCs come in a variety of styles, but generally fall into two categories: Jacket Style Scuba BCDs and Back Inflate Scuba BCDs.

Jacket inflation means the bladder (the compartment that holds air) surrounds your torso like a jacket. Jacket Style Scuba BCDs are best suited for divers who need to maintain a vertical orientation or spend a lot of time on the surface (ie: shore divers).

Back Inflate Scuba BCDs place the bladder behind the diver. Many divers find this more comfortable, as it allows for easier movement of the arms and feels less restrictive. A rear inflation BC also helps divers maintain proper horizontal attitude while underwater.

Snorkelers often appreciate a third kind of buoyancy control device, the Snorkel Vest, which provides much needed buoyancy when snorkeling on the surface.

Choosing a buoyancy compensator device can be overwhelming for first time scuba divers. There are 4 main components in searching for the correct bc. Safety should always be the first concern in all scuba diving equipment purchases. It is no different in searching for a buoyancy compensator device. A diver should look for one that has strong retention of air. A good buoyancy compensator device will retain air in all conditions and after harsh treatments. A high lift capacity is beneficial because it holds the diver high out of the water on the surface, helps maintain neutral buoyancy at depth and the extra capacity to help assist a buddy in need. Another important safety feature is a single handed quick release weight system.

The second main component in searching for the correct bc is comfort. Divers need to be comfortable in any buoyancy compensator device that they choose. Divers should choose one that provides air cell inflation without squeeze. It must be designed to fit properly. There are bcds that are specifically designed for women such as the Oceanic Hera Womens BCD, Zeagle Lazer Womens Scuba BCD, and Mares Aliikai Womens BCD. These will be much more comfortable for women than a standard buoyancy compensator device as they are contoured with size, shape, and style dedicated to females. The Zeagle line of bc’s feature a personal fit system which allows each individual to tailor the fit to each individual specifications. This makes for a perfect overall fit.

The third main component in searching for the correct bc is durability. Scuba diving can be a rugged sport and a diver needs equipment that can stand up to all different conditions. Divers should look for double stitching and the highest quality threads and bindings. Major manufacturers such as Mares, Oceanic, Aeris, Cressi and Zeagle have done extensive UV, abrasion, salt and chlorinated water testing. Divers know they are purchasing durable gear.

The fourth main component in searching for the correct bc is based on a divers needs. There are travel divers, recreational divers and technical divers. There are divers who dive often and those who dive once or twice a year. Each diver is different but the good thing is there is a buoyancy control device designed for every diver. Ideal bc’s for the avid traveler would be the Cressi Back Jac BCD, Mares Icon MRS Scuba BCD, or Zeagle Stiletto BCD. They pack up small and lightweight yet are still comfortable and rugged for the the toughest conditions.

Choosing a buoyancy compensator device comes down to preference. There are many choices and features of a bc that can make the decision overwhelming. Divers Direct has trained individuals to assist divers in making a confident gear purchase. Make Divers Direct your #1 stop for scuba gear.
