Find hidden treasures, track your suspects, mark secret meeting points, and create your own scavenger hunts with this location tracker. Hone your tracking skills to become a super sleuth!

The transmitter emits silent, ultrasonic sound waves, which you can detect and track using the handheld detector. Hide the transmitter with a valuable object, an important case document, or a suspect, and then use the detector to search for its whereabouts. When you get close to the transmitter, the LED display on the detector lights up, leading you to the transmitter.
