Find your crashed drone quickly with the Finder 2 Drone Buzzer from VIFLY. Compatible with any FPV quadcopter flight controller or RC airplane receiver, the Finder 2 can be activated when your vehicle goes down, emitting a very loud beep at 110 dB. In addition to sound, you can track your lost drone by sight. The Finder 2 can control its LED light and make it flash based on its built-in light sensor, which can detect ambient light intensity. Even if the vehicle's battery is ejected in a crash, VIFLY's ViSense-based technology allows the Finder 2 to operate.
