The 100% natural rutting buck urine in Tink's Trophy Buck Lure is collected from dominant bucks and reinforced with tarsal gland and interdigital gland secretions. The rutting odor of a buck induces a territorial challenge to another buck and provokes him to seek out the foreign buck. Also works as a curiosity lure in early season when bucks are traveling together. Comes in a 2-oz. glass bottle.
