Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
A method for avoiding detection by game animals by scent of a hunter through establishing wind direction to insure that the hunter is positioned downwind from the animal, comprising the steps of providing a quantity of finely divided powder-like hydrophobic material undetectable by smell by the animal; furnishing said material with a natural masking scent having an odor chosen from the group consisting of acorn, pine, apple or cedar, said scent being identifiable by the animal and serving to mask the scent of the hunter; dispersing into the air in a relatively small cloud at a location removed from the animal a quantity of said material; and observing the direction of travel in the air of said cloud of material to establish wind direction.
Claim 2
Independent Claim
124 words
A method for avoiding detection by game animals by scent of a hunter through establishing wind direction to insure that the hunter is positioned downwind from the animal, comprising the steps of providing a quantity of finely divided powder-like hydrophobic material undetectable by smell by the animal; furnishing said material with a natural masking scent having an odor chosen from the group consisting of acorn, pine, apple or cedar, said scent being identifiable by the animal and serving to mask the scent of the hunter; dispersing into the air in a relatively small cloud at a location removed from the animal a quantity of said material; and observing the direction of travel in the air of said cloud of material to establish wind direction.
Claim 3
Dependent Claim
13 words
The method according to claim 1 wherein said material is dispersed by spraying.
Claim 4
Dependent Claim
17 words
The method according to claim 2 wherein said material is dispersed by a gaseous propellant under pressure.
Claim 5
Dependent Claim
28 words
The method according to claim 3 wherein said propellant is air, said material being sprayed by manually squeezing a hand-held spray container holding a quantity of the material.
Claim 6
Dependent Claim
25 words
The method according to claim 1 including limiting the size of said cloud so that it is visually undetectable by the animal at a distance.
Claim 7
Dependent Claim
19 words
The method according to claim 1 including furnishing unscented raw talc as a portion at least of said material.
