Secure, streamlined, and instantly releasable — an integrated weight solution designed to work seamlessly with your Halcyon wing system. The Halcyon ACB (Active Control Ballast) Weight System is a purpose-built weight pocket solution for divers using Halcyon harness and wing configurations. Designed with both safety and practicality in mind, each ACB pocket securely holds up to 5lbs / 2.3kg of soft or hard weights in a vertical orientation that minimises harness clutter and keeps your setup streamlined in the water. A robust side-release buckle ensures your weights stay exactly where you put them throughout the dive, while still allowing rapid, one-handed release when it counts. Between dives, the removable weight pouch features a built-in carry handle for easy, secure transport at the surface — a small detail that makes a genuine difference on busy dive days. The Halcyon ACB Weight System integrates equally well into recreational and technical setups, offering a reliable and adaptable ballast solution for divers at any level who demand a clean, functional harness configuration.
