Primos Rack-N-Roll Deer Rattling System mimics two mature bucks fighting with the Primos Rack-n-Roll. Designed and tested in a sound lab where a real recording of two 140" class bucks were broken down and analyzed by tone and frequency. Individually toned nodes were created and mated to the tones produced by mature bucks in battle. Multiple sections of nodes are combined to create the volume and realism of 2 full sets of antlers coming together
