This little device can plug in-line between the servo and the receiver, or into a spare channel of the receiver. If you model goes down in high grass or any area that you can't easily see it simply turn off the transmitter, and after about a minute the plane finder will beep. The finder will then beep every 10 seconds. These also serve as reminders in case your forget to power down you model.
