This single wafer works to create a "No Smell Area" by relaxing the nasal detection areas of animals, ensuring they can't pick up human odor. Ideal for use in the field, simply hang it in a tree or blind and let the wind disperse the scent. For maximum effectiveness, especially in light to no-wind conditions, it's recommended to pair the wafer with the Scent Thief Field Spray. The wafer is oil-based, offering a slower evaporation rate than water-based sprays, which enhances longevity. Each wafer comes in a resealable pouch for multi-use, promising you a stealthy hunting advantage for two full days or four hunts, with the option to refresh it with the field spray for extended utility.
