The Ultrajax II String Silencer has been our most popular model with bow companies and consumers. It's been a top seller because of its effectiveness and they are the longest lasting. Ultrajax II String Silencers require a bow press, and they slip over the bow string to effectively dampen the noise, vibration, and oscillation that occurs after the shot. Bow does not loose velocity. Testing shows a usual increase of 1 - 3 fps. They weight only 19 grains each and come in black, red, silver, blue, pink, purple, brown, olive, orange, dlo green, and yellow flo green. For compound bow users that are looking for even more dampening ability, attach a Ultrajax II to your cable.
