ViFly Finder 2 Drone Buzzer

The VIFLY Finder 2 is a self-powered drone buzzer designed to save your quad after a hard crash. When an impact ejects your main flight battery, standard flight controller buzzers immediately lose power and fail. The Finder 2 takes over, detecting the power loss and drawing from its internal battery to emit a piercing alarm. It is an essential insurance policy for freestyle builds, bando bashers, and long-range rigs where a lost drone means losing expensive electronics and action cameras.

Key features

• Self-powered reliability: Automatically triggers a continuous alarm if the main LiPo is disconnected during a crash.

• 105dB alarm: Generates a significantly louder tone than standard 5V active buzzers, ensuring your quad is heard across large fields or through dense brush.

• Smart LED with light sensor: An integrated sensor detects ambient darkness, automatically pulsing a bright white LED to help locate your drone at night.

• 30-hour runtime: The internal battery provides over a day of continuous beeping, giving you ample time for recovery operations.

• Simple disarming: Silence the buzzer safely after a flight by holding the onboard button for 1-5 seconds, or by temporarily reconnecting and disconnecting the main flight battery.
