A wing BCD is a type of buoyancy control device (BCD) often favored by technical divers or those needing to carry substantial equipment, providing a streamlined profile compared to traditional jacket-style BCDs.
Here's a breakdown of what defines a wing BCD:
-
Buoyancy Bladder Placement: Unlike jacket BCDs where the air bladder surrounds the diver, wing BCDs position the bladder behind the diver, between the tank and the diver's back. This "wing" shape provides buoyancy where it's most effective for trim and stability.
-
Streamlined Profile: By placing the bladder behind the diver, wing BCDs reduce drag in the water, making movement easier, particularly when carrying multiple tanks or accessories.
-
Modular Design: Wing BCDs are generally modular, consisting of a backplate, harness, and the wing (air bladder). This allows divers to customize their rig with different sized wings, backplates (aluminum or stainless steel), and accessories like weight pockets and D-rings.
-
Enhanced Trim and Stability: The rearward placement of the buoyancy allows for superior control over the diver's horizontal trim in the water. This is especially important for technical diving where precise positioning is critical.
-
Customization: Wing BCDs can be tailored to the specific needs of the diver. For example, a larger wing might be needed for carrying stage cylinders, while a smaller wing suffices for recreational diving with a single tank.
In summary, a wing BCD is a highly customizable and streamlined buoyancy control device offering enhanced trim and stability, often favored by technical divers and those requiring the ability to carry a significant amount of gear.
