The Halcyon Active Control Ballast System has two ways to position and adjust your weight pockets. The other option is to place the pockets vertically. Both systems can hold a maximum of 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 your weight
A Trim weight pocket is a revolutionary new feature of the Halcyon tank-mounted weight pockets. It allows divers the ability to shift up 10 lb. To increase in-water stability, horizontal trim and reduce gas consumption, the pockets can be attached to their cylinder. They also counterbalance buoyant effects caused by nearly empty cylinders. A weight pocket allows divers to enjoy more bottom time, less effort and maximize their enjoyment when diving.

Active Control Ballast, integrated system
The ACB is a vertically integrated, releasable weight-system that can hold up to five pounds 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 are designed to prevent lead weight loss by allowing quick access to weights when necessary.
Mounting on a neck strap
Halcyon's new tank-mounted trim weight pockets encourage optimal weight distribution and promote 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. These are the pros and cons to tank-mounted weight pockets.
Heads-up surface airway protection
The Halcyon Trim Weight Pocket by manufacturer Halcyon is an innovative invention. It helps to ensure optimal weight distribution, and in-water stability. 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. This feature can increase the enjoyment of diving by extending bottom time. In addition to the positive benefits of moving weight from the waist to the cylinder, the Halcyon Trim Weight Pockets counteract the negative effects of near-empty cylinders and reduce the amount of effort required for the diver to maintain their head and maintain a horizontal position.

Cost
Whether you're looking to enhance your diving performance, or are simply looking for a way to keep your weight evenly distributed, Halcyon weight pockets are an excellent choice. These pockets slip over the tank’s cam bands and give you a secure place to add weight. These pockets can hold 5 lb to 5 kg of ballast, depending upon the tank. While the price of Halcyon weight pocket will vary depending on brand, it is well worth it.
