Pawscout uses a low-energy Bluetooth radio signal with a range of approximately 300 feet. You can use the Pawscout App to locate your pet and set a virtual pet leash that alerts you if the pet moves outside of that range. If you are not in range of your pet and you mark your pet as lost, you will be notified of your pet's location if he or she passes by anyone with the Pawscout App. To best protect your pet, ask friends, family members, neighbors, and caretakers to install the Pawscout App. Tracking will not work unless your pet is within 300 feet of someone with the Pawscout App.
