ShadowGPS - Magnetic GPS Tracker Case for Cars - Weatherproof Under-Vehicle Mount & Hidden Key Holder, Fits ShadowTrack - Black

Could you clarify what you mean by “radius”? Most customers are referring to one of the following: - Coverage: The device has a built-in cellular SIM card and does not use Bluetooth. It works independently of your phone and is not limited by distance. - Geofence radius: You can set custom geofences in the app, from small areas like a parking lot to much larger zones such as neighborhoods or cities. - Accuracy: Location accuracy is typically within a few meters when GPS signal is strong. Happy to explain further once we know which one you’re asking about 😊
