Scent probes are made from high-quality PVC and feature holes throughout to evenly distribute the scent from the training aid. Simply slip off the end cap to fill with the training aid of your choice then bury the tube or place it where the dog will not mouth it. They can be used for any scent training including truffles, cadaver, water, drug, and arson.
Each probe measures 17 x 2. 5 cm (c. 7 x 1 inches).
