Made of genuine doe-in-estrus urine, this scent fogger is perfect for use during the pre-rut and rut to stimulate aggressive breeding behavior in bucks. Just shake, depress pressure valve, and prepare for a great hunt. This easy-to-use, cost-effective fogging system produces a strong cover scent that reduces the need to read deep into a mature buck's home turf. Scent Protect Technology stops bacterial growth, stabilizes PH, and ensures that the strong scent will withstand temperatures greater than 100°F for extended periods of time. When used properly to blow into heavy cover where whitetails bed, it can tempt a dominant buck to break his nocturnal pattern and show himself before shooting light expires. Spray can be dispersed intermittently in short bursts, or the valve can be locked in the down position to empty the entire contents for maximum coverage. 5 oz.
