ABSTRACT:
A method for avoiding detection by game animals by scent through establishing wind direction to insure that the hunter is positioned downwind from the animal. In the method, a small quantity of a hydrophobic material such as unscented raw talc powder, which may be mixed with a natural masking scent material, is sprayed into the air in a relatively small cloud by means of a hand-held manually operated squeeze bottle. The direction of travel in the air of the cloud of material may then be used to establish wind direction. The material is such as to be undetectable by smell by the animal, and the size and characteristics of the powder cloud is such as to be visually undetectable by the animal at a distance.
