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:

Very true, but no one said that they are making it silent. Just dampening the noise. A sudden spooked deer is different than an attentive one. Try this for your experiment. Next time you are in the woods. Smack to pans together and see if the deer jump from being startled. Then just snap a twig and see what he does. The less sound traveling will give you just that much more of a chance of keeping a deer from "jumping the string". A few db's could be the difference between a spooked deer or a curious deer that may turn quickly to check out the sound rather than jump in an instance at the sound. I think I will take my chances with lesser db's. And FYI I have tested this quite a bit (not on goats either, it was actual deer) but I still may be Deluded.

I agree....that is where I noticed it most was when I had someone else shoot it while I stood away and listened.
