The Hamskea Hybrid Hunter Pro Microtune Arrow Rest uses the latest technology to create a smooth experience that is 26% lighter than the VersaRest platform. Zero Tolerance Technology ensures no lateral play in the shaft and effortless rotation action. Two oversized sealed stainless steel ball bearings provide lasting durability to keep your shot smooth time after time. For tunability, the textured spring knob provides multiple adjust positions to change the rotation tension of the launcher shaft. Coupled with the 8-sided non-slip compression clamp design of the lever arm, and the anti-bounce back dampening coil, you have all the elements to maximize your accuracy.
