Most buoyancy compensators (BCs) come with d-shaped metal or plastic rings that are used to attach dive accessories to the BC. Chest and waist straps may also have d-rings sewn into their ends to facilitate tightening the strap. Strap d-rings are not ideal for accessory attachment because the accessories will dangle below the diver and may damage coral or other delicate aquatic life.
When choosing a buoyancy compensator, a diver should consider whether the d-rings are easy to reach and convenient for accessory attachment. A BC should have d-rings on the shoulder or chest area and on the lower potion near the BC waist band or pockets, but ideal d-ring placement will vary from diver to diver. A diver should consider how and where he will attach his submersible pressure gauge and alternate second stage regulator to the buoyancy compensator.
