Any Bluetooth tracker has range limitation. Bluetooth based technologies such as Tile can track between 10meters to a maximum of 50 meters. They may be helpful in finding keys at home if your phone is close by to the missing item. With severe range limitation, they can only track when the missing item is in close proximity to your phone.
YoGPS GPS Tracking devices, also known as YoGPS GPS Trackers, have no range limitation. YoGPS can track your car, truck, boats, equipment or even vulnerable loved ones anytime anywhere.
You could be 100 miles or a 1000 miles away from your car and you would still get location updates and instant alerts with YoGPS GPS Tracking solution.
