Finding a GPS TrackerUpdated 2 years ago
Both LawMate devices the RD-10 and RD-30 can pickup 3G/4G signals. Most GPS trackers go to sleep after 10 mins of inactivity.
When conducting a sweep of your car be sure to turn your mobile phone off and drive to a less residential area as WiFi signals can also be picked up by the Detector.
It's also worth using a Hoist to check the under side of the vehicle if at all possible.
