Limbsaver FW1 Stabilizer Enhancer Black. One of the most crucial aspects of these types of Add-Ons by Limbsaver is the double broadband design of these attachments. Having two Broadbands on your stabilizer enhancer greatly reduces vibrations and allows your bow to settle faster which ultimately allows you to take more accurate shots down range. You can stack these attachments together to add more weight and the threaded end of these enhancers allow you to add even more weight later using the integrated 5/16in threads. The impressive Limbsaver FW1 Target Stabilizer Enhancer can help you immensely improve your accuracy on every shot.
