BCD or Buoyancy Control Device

The BCD, also called BC, stands for Buoyancy Control Device or Buoyancy Compensator. It’s the vest that holds the tank. But, most importantly, it’s the one you use to control buoyancy.

The BCD has many different features to control the buoyancy, depending on the brand and type.

There are an inflator and a deflator mechanism and on a typical BCD (this is used to add or release air to and from your BCD). The inflator and deflator are usually located on a hose connected to your left shoulder.

Most BCDs come with a few pockets and D rings for carrying gadgets on the dive; some having weight pockets as well.

BCD’s come in different forms and shapes: jacket-types and wing-types. The jacket is more popular for most divers and gives great comfort underwater and in the surface. The wing-type BCD gives better buoyancy and enables a perfect horizontal possession during the dive.

Here are some great BCD’s you should look at before deciding which to buy.

All the Scuba Gear We've tested

Best for Beginners

The Cressi Start was initially intended to be used by dive schools and resorts. It has a basic design but is highly functional making it ideal for beginner divers too.

One nice feature is that the waist strap is independent of the air bladder, so if you tighten it while the jacket is deflated, it’s not going to squeeze your stomach too much when you inflate.

If you are looking for a BCD that is reliable and almost bullet-proof, the Cressi Start is a great entry-level option.

Cressi Start

Definitely, a BCD designed with women divers in mind. It features thick padding on the inside with a plush nylon finish. The jacket and air bladder are specially cut for a snug fit to female curves.

Sherwood uses a unique Halfpac backplate which offers the versatility of soft backplate with the stability of a hard backplate. This means it’s extra comfortable but will also hold your cylinder firmly in place.

One great feature of the Sherwood Luna is the padded neoprene neck. A small hint of color adds a nice feminine touch.

Scuba Regulator

The regulator set consists of a 1st stage, which is mounted on the tank valve. Then there are two regulators in the 2nd stage: a pressure gauge and a low-pressure inflator hose that is attached to the BCD inflator.

  • The regulators have a primary and an alternate air source. The alternate air source is for you or your buddy in an emergency or a back up is needed.
  • A modern regulator is a demand valve regulator, which means it give you air when you want it. When you breathe in, air flows from the tank through the 1st stage and to the 2nd stage supplying air to you.
  • The pressure gauge shows how much air is in the tank and usually has a caution area that warns you when the air is getting low.
