This device is to be used in conjunction with the Stinger Kill Spring, turning the device into a legitimate power snare. The trapper compresses the spring with the Senneker Snare Setter and latches the trigger on the spring. The target animal fires the spring after the snare has set on the neck resulting in positive and humane snare dispatch. Can be added to existing snares by cutting the end stop, adding the trigger and replacing stop. For best results use with authentic Stinger Kill Springs that can handle the load.
