Tink’s Trophy Buck Lure is 100% natural rutting buck urine collected from dominant animals and reinforced with tarsal gland and interdigital gland secretions. The rutting odor of Trophy Buck induces a territorial challenge to the buck and provokes him to seek out the foreign buck. Excellent product to use when rattling or grunting. This same lure works as a curiosity lure in early season when bucks often travel in bachelor groups.
