STS on excalibur crossbow
 

has anyone put a string stopper system on an excalibur crossbow and if so how much did it quiet the bow

I made my own for all three of my bows. They mostly give me peace of mind in case of partial dryfire. They do reduce vibration a bit but noise is not significantly reduced. To do that you must shoot a heavier (slower) arrow, use a thicker string with cat whiskers. And even then it won't be anywhere as quiet as a vertical bow; simply because the pull weight of a crossbow is at least twice as great.

I just took a pair of the Sims Limb dampeners and put one on the end of each limb where the string just barely touches it when un****ed . Probably slows my arrow down but it quietens it a little

Using the sts system on my excal exocet. I did not have to change the varizone scope at all for yardage so if there is a decrease in speed at all it is not enough to change my trajectory. As for noise it made quite a bit of difference on my bow.

I didn't notice a lot of noise reduction on my Emax when I installed one, but the following arrow flight through scope was worth the price of admission to me, along w/ lack of limb damage in the event of a dry fire w/ FFF string. YMMV.

Slowed my Equinox by 15 fps when I tried it...more than I could handle for the little noise reduction I got in return.

The reduction of noise that I can really tell the difference in is when I have someone else shoot my bow while I am 20 yards away. With the sts it made a pretty good difference of down range noise.

Never tried that and I get my hearing aids from the Gubbmint, lol. I can tell you this, w/ my now departed Emax, a Boo string, STS, 446 gr arrows was as good as it got in a few years of experimenting w/ it. YMMV.

Good as they may be at silencing noise (for our ears), don't come even close to what a deer can hear. Last night I tested that on a nanny the was some 40 yards out by removing the rubber band that holds my monopod in place. The noise was barely perceptible to my ears, a gentle swish, she heard it laud and clear. On another one I barely tapped an arrow in my quiver. Same thing. Anyone who thinks that noise suppressors on crossbows will keep deer from hearing the shot is deluded or hasn't tested it.

I put a set on my Phoenix and they did reduce the noise & vibration some, but I didn't leave them on. :rolleye0011:

I also removed the DBs from the bow. (I hate to fool with removing the pads when I store it unstrung)

All I use for noise reduction is a Boo string with catwhiskers.

Keep shots withing reasonable range and it doesn't matter if the bow is loud. :happy0157:
