Backplate and Wing BCD Systems for Scuba Diving

Discover the versatility and performance of Backplate and Wing (BP/W) BCD systems, the preferred setup for technical, cave, and advanced recreational divers. This modular system combines a sturdy backplate, a harness, and an interchangeable wing, offering superior customization, durability, and streamlined buoyancy control for any diving environment.

Why Choose a Backplate & Wing?

• Modular design: Mix and match backplates, harnesses, and wings to suit your needs.
• Durability: Stainless steel, aluminum, or carbon-fiber plates built for longevity.
• Streamlined profile: Low drag for technical dives, wreck penetration, and caves.
• Custom fit: Adjustable harness systems tailored to your body and exposure protection.
• Wing selection: Swap wings for single-tank, double-tank, or travel setups.
• Weight distribution: Backplate weight helps trim and reduces the need for additional lead.

Key Features to Compare

• Backplate materials: Stainless steel for ballast, aluminum for travel, carbon fiber for lightweight strength.
• Harness options: Continuous webbing for simplicity, deluxe harnesses for added padding and adjustability.
• Wing lift capacity: Typically 20–40 lb for single tanks, 40+ lb for doubles and technical configurations.
• Wing shape: Donut vs. horseshoe designs for buoyancy distribution and trim control.
• Accessories: D-rings, crotch straps, and weight pockets for complete customization.

Who They’re Best For

Technical divers: Needing modularity for doubles, stages, and sidemount transitions.
Experienced recreational divers: Wanting a long-lasting, customizable BCD.
Travel divers: Using lightweight aluminum or carbon plates with compact single-tank wings.

Buying Tips

1. Choose the right plate: Steel for built-in ballast, aluminum or carbon for travel convenience.
2. Match wing lift: 20–30 lb for warm-water single tanks, 40+ lb for doubles or drysuit diving.
3. Select harness type: Continuous webbing for minimalism, deluxe harnesses for comfort and quick adjustability.
4. Check compatibility: Ensure the wing and backplate bolt pattern match (standard 11-inch spacing).
5. Add accessories wisely: Trim pockets, weight systems, and D-rings to suit your diving style.

Maintenance & Care

• Rinse wing and backplate thoroughly after saltwater dives.
• Flush bladder and valves to prevent salt buildup.
• Inspect webbing and hardware for wear before dives.
• Store the system dry, partially inflated, and away from UV exposure.
• Replace worn webbing or O-rings as needed—parts are modular and easy to service.

Frequently Asked Questions

What is the main advantage of a backplate and wing system?

The modular design lets you customize your setup for different dive environments, offering superior durability, trim, and adaptability compared to traditional jacket BCDs.

Can beginners use a backplate and wing?

Yes. While popular among technical divers, many recreational divers enjoy the stability, simplicity, and longevity of BP/W systems from their very first dives.

Which wing size do I need?

For single-tank warm-water diving, a 20–30 lb wing is sufficient. For doubles, cold-water, or drysuit diving, choose a 40 lb or larger wing for adequate lift.

Are all wings and backplates compatible?

Most follow the standard 11-inch bolt spacing, but always confirm compatibility between wing, plate, and harness before purchasing.

Do I still need a weight belt with a steel backplate?

Often less or none. A stainless steel backplate adds 5–6 lb of ballast, reducing or eliminating the need for extra lead in many setups.
