[ Ссылка ] - The Simple GPS Tracker is a two-part electronics device that helps you find your rockets or RC airplanes after a flight. It uses a small airborne transmitter (part one) inside your rocket that sends it's GPS location to a handheld reciever (the second part) that you carry with you. The receiver has a simple pointer indicator on its screen, which tells you which direction to walk in order to retreive your rocket. It even tells you how many more feet you have to go, and it generally lead you to within 5 to 10 feet from your rocket.
