US Patent 8181826 Scent sprayer

The scent sprayer is a device for attracting animals. The device incorporates a scent spray dispenser. The dispenser includes an optionally camouflaged housing with a wind vane for rotating the sprayer in the direction of the wind. A radio frequency (RF) receiver is enclosed in the housing. The receiver is connected to a circuit that operates an electromechanical coupler to release a scent from the scent spray dispenser that attracts game. The scent sprayer also includes an RF transmitter that transmits a control signal on the same frequency as the RF receiver to trigger release of the scent. The scent contained in the scent spray dispenser may be urine, blood, pheromones, or any other scent suited to the game being hunted.
