Internal Bag separates the urine from the pressurizing agent so there is no contamination. System allows the entire product to be dispensed. Sprays longer than traditional spray cans. Trophy Buck Lure is 100% natural rutting buck urine 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. Tink's Trophy Buck Lure works as a curiosity lure in early season when bucks often travel in bachelor groups.
