i bought a set of bow jax.didnt put em on my string but did on my cables they attach with cable ties so i can take off and put back on at a whim.ive had both my kids turn there backs and the could tell when i had the bow jax on or off.i use alum bolts so my crossbow wont be as loud as if i used carbon bolts.then agin its a crossbow you can add some things but there goona be loud regardles.the 2 deer ive shot didnt jump the string and they where shot @22 and 26 yards.i also use the sims limb attactments too which help with vibration.no quiver attached and i can honestly say it aint as loud as some bows ive heard shot.hope this helps
