After 2 years of testing and re-testing we totally re-designed our popular string stop for 2008. This new model mounts to the rear as our previous design, but this year we have added an adjustable base which allows you to easily make adjustments to the length, and a dampener has been added to stop even more vibration. What sets ours apart from the competition is our patented revolutionary powder fill inside the stop rod to dissapate the broadest spectrum of string oscillation, bow noise and vibration, making it the best performing string stopping device on the market. Stop whacking your arm and hunt with more clothes on without worrying about the string hitting your jacket, The String Stop eliminates the arm slap effect. MUST HAVE REAR STABILIZER HOLE.
