While they've become the visual identifier of a Mathews bow, Harmonic Dampers are weights that float in an elastomer wheel to absorb recoil vibration in the riser. The reduction in recoil vibration is so significant in this Mathews technology that is has been licensed for use in other industries.
Traditional cable rods were subject to unwanted friction. The roller guard, another Mathews first, dramatically reduces system friction by guiding bow cables with low friction wheels.
The Harmonic Stabilizer™ is another exciting innovation from Mathews Inc. The Harmonic Stabilizer™ will give optimum performance and dampen more than 75% of residual vibration! Standard on the Reezen and Monster. Available as an accessory for older models.
Mathews Quad V-Lock Limbs™ are extremely durable and longer lasting because the pressure is spread out over a larger surface area, meaning there is less stress on the limb.
The Advanced Vectoring System™ (AVS) is a totally revolutionary cam system that enables higher levels of performance and efficiency than ever before.
String GrubString Grubs aid in reducing string vibration in order to gain more speed.
