I saw a pic of, I think, a Bear Carnage that had dual string suppressors.
One suppressor or dual suppressors? How about none? None equal less to adjust or worry about. This quiet BS is just that, BS. What's noisy on a bow? Well, for one, quivers. Another, some of the slider sights. Vital Gear probably had/has one the best sliders out and mine was a pure rattle trap. My hunting bow has only Limb Savers bolted on the limbs, nothing else. No string leaches, no whiskers, no quiver, no nothing. Shortest kill shot was right off the arrow. Longest kill shot was 36 yards. Two or three deer were looking right at me right before they headed for the freezer.
Is the sight noisy? Find out. Take it off the bow and shoot the bow. My sight is dead silent.
Arrow dragging noise from the rest launch arm. Coat it with something and make sure to check it for wear. A roll of electrical tape will last a quite a few thousand shots - last probably a few bows worth. Small can of that rubber coat stuff used for tools. Scentless finger nail polish will last quite a few shots. I hate those prong nylon covers. So thick and then people wonder why their point of impact changed when the nylon cover is wore down to the prong. Of course, a lot of the wear down and some noise is due to setting the rest improperly or poor bow tune. (Off subject, but the shoot through prong style rest should have the spring tension set so the arrow will not come up fully on it's own. Quick instruction; Set the tension so the arrow comes up through drawing the bow.)
