ViFly Finder Mini Drone Buzzer

The VIFLY Finder Mini is a self-powered lost-drone alarm designed for compact FPV builds where weight is critical, such as sub-250g micro quads, whoops, and toothpicks. Weighing only 2.7 grams, it provides the security of a standalone buzzer without bogging down lightweight flight envelopes. Unlike standard active buzzers, it features a built-in battery to ensure it will continue beeping even if the main flight LiPo is ejected during a crash.

Key features

• Autonomous power triggers the alarm automatically upon flight controller signal loss or battery ejection.
• Delivers a loud 100 dB beep pattern to cut through environmental noise.
• Integrated flashing LED acts as a visual strobe to aid recovery in low light or dense foliage.
• Smart silencing allows you to disarm the buzzer via the physical button or a quick main-battery replug sequence.
