With today's high-tech, superfast compound bows, shock, vibration, and noise are bugaboos that bowhunters must control to achieve consistent arrow flight and prevent game from jumping the string when the arrow is released. The Golden Key Futura Tranquilizer has been shown to reduce the noise from a bow shot by up to 12 decibels and to reduce vibration by up to 70 percent. At just 51ZÂ¿Â¿2 ounces, its 71ZÂ¿Â¿4-inch length preserves a bow's balance. It's available in six popular camo patterns as well as solid black. About $40-$45. Golden Key Futura, Dept. FS, P.O.
