The possibilities are nearly endless. Got a wayward pet that likes to run off? Nervous about taking your young child to a big festival? How about that teenager just learning to drive? Or perhaps you’re a builder leaving expensive equipment on a construction site. I think you get the idea.
Summary: The Garmin GTU 10 is a good tool for tracking and finding lost things, but its positioning accuracy is dependent on the geography around it and the frequency of its reporting.
Pros: The Garmin GTU 10 's geofences function sends notifications when the device is brought into or out of a user-defined area. You can track the GTU 10's location and adjust its settings online via a Web app or on a smartphone with the Garmin Tracker app for iPhone or Android.
Cons: Blocking the GTU 10's view of the sky can compromise its positioning accuracy, making it less than ideal for use near tall buildings.
