BC System Weighting

Active Control Ballast

Halcyon ACB (Active Control Ballast™) integrated weight pockets are an ideal solution for divers seeking releasable weight for their Halcyon BC system. This patented Halcyon design is simple and effective; when complemented by our fixed and removable ballast options, these pockets fine tune system weighting while supporting stability and diving comfort.

  • Simple tri-glide connection secures the ACB on the Harness waist band
  • Allows mounting of an Explorer Primary light behind the ACB pocket
  • Side release buckle prevents accidental weight loss but can be quickly released
  • Can be used with most soft or hard dive weights
  • Removable weight pouch features an easy-carry handle
  • Halcyon’s ACB Integrated Weight Pockets are protected by US Patent 6527480




Halcyon Trim Weights

Halcyon tank-mounted trim weight pockets are yet another novel Halcyon invention. This patented product supports optimal weight distribution, encouraging diving comfort and in-water stability. While at the surface, Halcyon trim weights promote a heads-up position, counteracting the positive tendency of buoyant cylinders. These same weights support a horizontal position while under water, reducing effort and encouraging diving fun.

Key Features of Trim Weights

  • Up to 5 lb/2.27 kg of weight per pocket
  • Built from 1,000-denier nylon with a hook and loop closure; a sturdy buckle ensures the weights remain in place
  • Designed to fit securely onto the tank straps
  • Excellent for travel, allowing you to fit additional weight upon reaching your destination
  • Halcyon trim weight pockets are protected by US Patents 5855454 and 6530725b1.


Weighted Single-Tank Adapter

Divers who are able to remove unnecessary weight from their waist enjoy greater comfort and better in-water position. The Halcyon weighted single-tank adapter places an additional six pounds between the backplate and single cylinder, removing weight from your waist and encouraging a more comfortable in-water position. The weight is easily removed during travel or when less weight is required.
  • Attaches securely to Halcyon Eclipse BC Systems
  • Epoxy-coated 6-lb. (2.7 kg) weight is easily removed
  • Removable weight may be purchased as part of the Halcyon BC systems
