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

- 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.

The weight is easily removed during travel or when less weight is required.- Attaches securely to Halcyon Eclipse BC Systems
