Sims Vibration HD S-Coil - The HD S-Coil is an all new dynamic stabilizer for 2015. This new design helps keep you hidden with its HD camouflage patterns. It is available in the most popular camo patterns to fit each hunter's preference. The HD S-Coil's redesigned geometry greatly reduces vibration, hand shock, and unwanted noise. Its short length of 4.5a ^2 is perfect for the hunter who wants minimal interference while shooting in tight spaces such as tree stands or brushy areas. No other compact, lightweight stabilizer can get the job done like our line of S-Coils. SimsVibration HD S-coilDynamic StabilizerGreatly reduces vibration, handshock, and unwanted noiseLength of 4.5"
