The Halcyon Active Control Ballast System offers two options for positioning and adjusting your weight pockets. You can place the pockets vertically with one option. Both systems can hold a maximum weight up to 2,6kg. The system has an Active Control Ballast (ACB), which can be adjusted to suit your needs. You need to ensure your equipment is safe and effective.
Trim weight pocket
A Trim weight pouch is a new feature on the Halcyon tank weight pockets. It allows divers up to 10 lb. to their cylinder for improved in-water stability, horizontal trim, and reduced gas consumption. The buoyant effect of nearly empty cylinders is counterbalanced by the pockets. A weight pocket allows divers to enjoy more bottom time, less effort and maximize their enjoyment when diving.

Active Control Ballast (ACB), integrated system
The ACB, which is a vertically-integrated and releasable system for weight management, can hold up 5 lbs of weight per pocket. This design allows for easy release and placement, and doesn't take up much space on a diver’s waist belt. An Explorer Light System can attach to the ACB pockets for increased versatility and safety. Side release buckles prevent accidental lead weight gain and permit quick access when required.
Mounting on bottle strap
The new Halcyon tank-mounted trim weight pockets promote optimal weight distribution, comfort and stability while diving. They also encourage the heads-up position, reduce effort, and in-water stability. Mounted on tanks, the pockets allow you to easily balance the weight of your tank cylinder for optimal in water stability. Here are some benefits and drawbacks to tank-mounted weigh pockets.
Heads-up surface airway protection
The Halcyon Trim Weight Pocket from the manufacturer is an ingenious invention. It promotes in-water stability and weight distribution. Divers who use this feature report that they are able to move weight from their waist into their cylinder. This improves horizontal trim and propulsion. Divers can enjoy a longer bottom time and a greater enjoyment from the dive. The Halcyon trim weight pockets provide positive benefits beyond moving weight from waist to cylinder. These pockets counteract the negative effect of near-empty containers and decrease the effort required by divers to maintain their horizontal position and head.

Cost
Halcyon weight pocket is a great choice, whether you want to improve your diving performance or simply keep your weight evenly distributed. These pockets slide on top of the tank's cam band and provide a secure area to add weight. Depending on the type of tank you're using, these pockets can hold anywhere from 5lbs to 5kg of ballast. The cost of Halcyon weight pockets will vary from brand to brand, but they are well worth the price.
