A detection system includes a mobile unit in the form of a trained/in-training animal controlled, either directly or indirectly, by a handler. The mobile unit carries a portable electronics package linked to a remote unit. The animal is trained to search for target odors originating from a specified object, such as drugs, weapons, chemicals, a person or the like. Once a target odor is detected, data generated by the animal, as determined through body position, biometric or other sensors provided in the portable electronics, is either stored in memory for later review or forwarded to a remote unit for immediate evaluation. In this manner, the handler is provided with confirmation that the animal has sensed a target odor, thereby increasing the overall efficacy of the detection system and reducing the possibility of incorrectly reinforcing responses that are not associated with the desired target odors.
