Buying guide: Buzzers & Locators
A lost-model buzzer helps you find a drone that landed out of sight. Compare the loudness in dB, whether it has its own backup cell so it keeps sounding after the main battery is unplugged, whether it adds an LED, and how it connects: most plug into the flight controller's buzzer pad, and Betaflight can trigger it on a switch or after a crash.
