Question: Have you stopped using string silencers on your crossbows?
Answer: YES. The reason is that we have long know string silencers and limb savers were ineffective on crossbows (unlike compound bows where they do a tremendous job) because the crossbow limbs and strings are much heavier. The silencing accessories are not big enough to dampen the vibration and noise created by a crossbow. Also, those components were easily damaged and lost. Leeches tore after a low number of shots and limb savers did not stay on the limbs so we had a huge number of warranty issues.
We began using them initially because we installed Sims products on all of our compound bows and still feel that their products are the most effective at dampening noise and vibration for vertical bows. Just not for crossbows.
