Shifting weight from a diver's waist toward their center, such as with a stainless Halcyon Backplate or trim weight system, facilitates horizontal diver trim and reduces drag Up to five pounds of weight can be attached to your tank with each streamlined trim weight pocket. They come always in pairs
