The Buck Bomb Scrape Generator Bomb contains 6.65 ounces of pure, fresh urine from estrus does and rutting bucks. For best results, use during the pre-rut through the peak of the breeding period. Each can of Buck Bomb features the NVERTR 180-degree ball valve that allows it to be sprayed in short burstseven upside down. Or, lock down the valve and empty the contents all at once to unleash a potent cloud of scent that can travel in excess of a quarter mile on a 3 mph breeze.
