A passive GPS logger, simply place the small iTrail unit wherever you like - your car, child's backpack, virtually anywhere, and the logger will record your exact location, speed, and time.
At only 1.5"x1.5" small, the SleuthGear iTrail is a historical logger, which means it records your location, speed, and time, and then displays this information on an easy-to-use PC interface powered by Google Maps and Google Earth.
Simply turn on the unit, and place it where you would like. The unit will record up to 120 hours of data. To retrieve the information, just plug the unit into your computer via the included USB/charging cable. You can then download the information to a detailed printable report and view in Google Maps or Google Earth.
