Perfect for use during spot and stalk hunting and when calling, Tink's Hot Shot Cow Estrous Mist is irresistible to bulls cruising downwind. An internal bag separates the urine from the pressurizing agent, so only 100 percent pure urine is dispensed. The can dispenses a powerful fine mist for long range attraction. It sprays at any angle, even upside down, and is quiet so it won't spook nearby elk. 3 oz aerosol spray.
