BackTrack Keychain GPS
|This is the simplest portable GPS locating device available, ideal for finding your car after shopping or your hotel after a day of touring in an unfamiliar city. Simply push a button to mark your current location and the device points the way back.
Half the size of a cell phone, the compact receiver fits easily on a keychain, in a pocket, or in a purse. Unlike typical GPS units that are highly complex, this one only has two buttons: one for switching your compass mode, another for setting up to three starting points.
