An essential addition to your boy, the Everlast String Leech from LimbSaver helps stop string oscillation and reduce up to 90% of string noise, giving you a noticeably smoother and quieter shot. Designed for use on compound and recurve bows, 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 for improved comfort as well as deadening and silencing your bow. This package includes four Everlast string leeches. Quick and easy to install, the Everlast is durably built to be used outdoors in harsh environments. Bow press or string separator required for installation; recurve bow string installation requires serving the leech in place. 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.
