Abstract: The leg mounted scent dispenser distributes liquid scent to mask human scent or to deposit a tangle free and consistent scent trail. The dispenser assists hunters in capturing game with weapons and cameras alike. The dispenser includes straps for attaching to a boot and to the lower leg of a person. The boot level strap connects to a canister filled with a scent of the hunter's skillful choice. The canister communicates with a drip valve, or alternatively a pump, that discharges a small portion of scent with each time the boot lands. The person regulates the desired scent flow and walks to a stand or tracks the game. Once at a stand or having taken the game, the hunter turns off the canister and removes the present invention for storage.

Abstract: A variable and regulated animal scent dispenser that allows a hunter or tracker to dispense discrete and variable amounts of animal or other scent in a continuous manner while walking through a forest or field. The lower part of the device is attached to the underside of a hunter's boot; the upper part of the device is clipped on to the top of the hunter's boot. As the hunter walks through the woods, the sole of his boot presses down on the compressible bladder, thereby sending air through a rubber or plastic tube to a manifold. Depending on the position of the manifold/regulator switch, the compressed air either bypasses a scent receptacle or enters the scent receptacle. If the compressed air enters the scent receptacle, it picks up particles of scent and transports them out the discharge tube and ultimately to the atomizer at the end of the tube. Scent is then dispersed through the atomizer onto the ground. This allows for a fairly continuous stream of scent.
