Spy Tec STI GL 300 GPS Tracker for Kids (small black and grey disc)The Spy Tec STI GL 300  is a small, but very powerful kids GPS tracker designed originally to track and monitor trucks. It is, however, a perfect GPS Tracker for kids of any ages – it can also be used to track adults, vehicles or equipment  in real-time.

You don’t need to download any App from the Google Playstore or iTunes. You can watch your tracker move in real-time in Google Maps and Google Earth. The Spy Tec device can be accessed using any browser from a tablet or a smart phone or even your desk top!

All of the tracking data can be stored for a year and downloaded at any time. You can even get custom reports summarizing your tracking data.

You will also be happy to know that this kids GPS tracker needs to be charged only once every 2 weeks – well, that’s the tracker’s maximum battery life.

Another useful feature related to this tracker is geo-fencing. You can set geo-fences (digital borders) around certain areas and receive text or email alerts when your kids GPS tracker enters and leaves these zones. All-in-all this is a very nifty little device which deserves the high ratings received from users.
