SEAC Modular Wing BCD

One BCD. Endless Possibilities.

The SEAC Modular Wing BCD has been designed for divers who want complete freedom to build a BCD around their own diving style. Whether you're a recreational diver looking for a streamlined wing or an experienced diver planning future upgrades, the Modular offers exceptional comfort, versatility and performance in one lightweight package.

Unlike conventional BCDs, every major component of the SEAC Modular can be removed, replaced or upgraded. From the harness and bladder to the backplate and integrated weight system, the Modular grows with your diving, making it one of the most adaptable wing-style BCDs available today. :contentReference[oaicite:0]{index=0}

A BCD That Evolves With You

The SEAC Modular isn't just another wing—it's a platform that can evolve alongside your diving.

Every major component is interchangeable, allowing you to replace worn parts, upgrade individual components or completely reconfigure your BCD as your experience grows. Whether you're moving into technical diving or simply want to customise your equipment, the Modular is built to adapt without replacing the entire BCD. :contentReference[oaicite:2]{index=2}

Compatible with a range of backplates, bladders and accessories, the SEAC Modular offers a level of flexibility normally found only on much more expensive technical wing systems.

Customise Your Modular

One of the biggest advantages of the SEAC Modular is the ability to configure it exactly how you want it.

The standard system includes two 2kg trim weight pockets, but many divers choose to upgrade to the optional SEAC Q&S Quick & Safe 6kg Weight Pockets, providing secure integrated weight storage with a positive locking system and rapid emergency release.

The Modular is also compatible with the optional:

• SEAC Q&S 6kg Integrated Weight Pockets
• SEAC Weight & Storage Pockets
• Additional Trim Weight Pockets
• Aluminium Backplate Upgrade

If you're looking for the ultimate integrated weight system, we highly recommend adding the SEAC Q&S 6kg Weight Pockets. They provide secure ballast storage, outstanding comfort and can be quickly released in an emergency, making them the perfect companion to the Modular Wing.

Travel Friendly Without Compromise

Despite its technical appearance, the SEAC Modular is an excellent travel companion.

The complete BCD weighs only 3kg and quickly dismantles into a compact package, taking up very little luggage space. This allows you to enjoy the comfort and familiarity of your own BCD wherever in the world you dive. :contentReference[oaicite:3]{index=3}

Exceptional Trim and Stability

The 13.6-litre rear-mounted donut wing keeps buoyancy behind the diver, promoting a naturally horizontal trim position underwater. This improves efficiency, reduces drag and creates a more streamlined diving experience compared with traditional jacket BCDs.

The result is better buoyancy control, improved gas consumption and a more relaxed dive, whether you're exploring UK wrecks or tropical reefs.

Perfect For

• Recreational diving
• Advanced divers
• UK diving
• Travel diving
• Wreck diving
• Divers moving from jacket BCDs to wing systems
• Divers wanting a fully upgradeable BCD
