Definition
A Backplate and Wing (BPW) is a modular buoyancy system composed of a metal backplate and an inflatable air bladder worn on a diver’s back.
More on Backplate and Wing (BPW)
The Backplate and Wing system is a popular choice among technical divers for its simplicity, durability, and streamlined design. It consists of a metal (steel or aluminum) plate for support, a one-piece webbing harness, and an interchangeable donut or horseshoe wing. Unlike traditional jacket-style BCDs, BPWs offer better trim control, fewer failure points, and modular customization. They are ideal for divers using twin tanks or diving in overhead environments, where equipment redundancy and mobility are critical.
Frequently Asked Questions
BPWs offer excellent trim control, reduced drag, and a minimalist, customizable setup. They’re durable and allow divers to tailor the system to specific needs like tech diving, sidemount, or cold-water configurations.
Yes, although there is a learning curve. Once adjusted, BPWs can be easier to dive than jacket BCDs and provide a solid foundation for skill progression.
Aluminum is lighter and favored for travel, while steel adds ballast and is better for cold-water diving with thick exposure protection.
Yes. Many divers use single-tank adapters (STAs) or cam bands directly through the backplate slots to secure single cylinders.
It refers to a minimalist harness style with one continuous piece of webbing, no quick releases, and a focus on simplicity and efficiency.
