Like most GPS tracking devices, the Garmin GTU 10 combines a physical tracking unit with a web-based interface to allow you to keep tabs on your luggage or other valuables. The GTU 10 is small, lightweight, waterproof and designed to be stupid-simple to use. Its best feature? The ability to draw “geofences” (virtual boundaries) for the device via the included app. Anytime your personal wares enter/exit the designated area, the Garmin tracking service sends an alert via e-mail or SMS. Nice.
Available now from Garmin.com for around $200 (includes one-year of tracking service).
