Connect your downrigger tow line to the center hole of the Zwing bracket – this is your tow point. Connect your fishing line to the downrigger line. The smooth hydrodynamic design puts you in complete control of depth and lateral location of your line. Downward force overcomes drag allowing for constant depth to be maintained at various trolling speeds.
Compared to the Lead Ball
Operating on the principle of hydrodynamic depression, rather than just weight, the Zwing overcomes the shortcomings of the conventional lead ball. The lead ball rises with speed. The Zwing's hydrodynamic shape increases downward pressure with speed. No more heavy lead balls rolling around the boat or swinging off the end of downrigger booms which can cause damage to both angler and boat alike.
Zwing is Easily Customized
The Zwing is made from, lightweight, virtually indestructible, polypropylene plastic. By applying a heat source (such as hot water) to the Zwing's back fin joints, a slight angle in the fins can be positioned and set. These offset fins will produce a horizontal angle in addition to the vertical downward angle. The Zwing will track away from the boat while maintaining desired depth. This feature is critical when fishing for spooky species like Salmon or Trout. Returning the fins to a straight position will enable the Zwing to regain normal tracking.
Besides depth, and tow position, the diameter of the tow cord can impact efficiency of the Zwing. Thicker diameter tow cords create more drag which must be overcome by downward force. Thinner diameter tow cords create much less tow cord drag and allow for more efficient performance and steeper angles of decent, expecially at slower speeds. Keep in mind, the Zwing does create downward pressure at fast speeds. Be sure your downrigger can support this pressure.
