SS Deluxe Backplate with ACB Pockets

If you're building a serious backmount configuration, the foundation matters. The Halcyon Stainless Steel Standard Backplate Deluxe is exactly what it sounds like — a bombproof, precision-engineered plate that forms the backbone of your Halcyon harness and wing system. CNC-machined from high-grade 304 stainless steel and individually polished to remove sharp edges, it's built to last the lifetime of your diving career. The Deluxe version comes with padding and cushioning for added comfort during extended dives or long surface intervals — a small but genuinely appreciated upgrade if you're wearing this kit for multiple dives a day. The weight of the plate itself contributes meaningful ballast, which is a real advantage for cold water divers or anyone suiting up in a drysuit — less lead on the belt, better trim in the water. This bundle pairs the backplate with the Halcyon ACB (Active Control Ballast) Weight Pockets — a purpose-built, integrated weight system designed specifically for Halcyon harness configurations. The ACB pockets attach directly to the harness waistband via a tri-glide connector, hold up to 5 lbs / 2.3 kg each, and keep your ballast positioned vertically to minimise clutter and maintain a clean, streamlined profile. A robust side-release buckle keeps everything locked in throughout the dive, while the removable weight pouch with built-in carry handle makes surface handling significantly less awkward. Small detail, big quality-of-life improvement on a busy dive day. Together, the SS Deluxe backplate and ACB pockets give you a complete, weight-integrated harness foundation that works equally well for recreational and technical configurations. If you're diving cold water, logging bottom time in a drysuit, or simply done with belt weights pulling your hips down, this combo deserves a serious look.
