LimbSaver's Super Cable Leech reduces cable noise and virtually eliminates cable oscillation. It's made from LimbSaver's proprietary NAVCOM technology (Noise and Vibration Control Material), which effectively absorbs a wide range of frequencies to dissipate energy and vibration. Quick and easy to install, the Super Cable Leech is durably built to be used outdoors in harsh environments. Using state-of-the-art technologies, LimbSaver produces highly effective noise- and vibration-dampening products for archery and firearm products, including bow stabilizers, recoil pads, rifle slings, and more. Proudly engineered and hand-made in the USA, LimbSaver products are widely used by outdoor enthusiasts, military, law enforcement, and more.
