Advanced ViSense Technology
With ViSense-based technology, the VIFLY Finder 2 can power itself to beep even the quad battery has been ejected. Even more, the built-in light sensor can detect light intensity and then smartly control the LED light to flash. Besides, it enables the buzzer automatically enter into sleep mode at night to save power and not disturb.
110dB Alarm - Much Louder than Standard Buzzer
The Finder 2 delivers up to 110dB of sound output, making it significantly easier to hear than typical FC-mounted buzzers.
Whether your quad crashes in grass, bushes, crops, or wooded areas, the loud alarm helps guide you directly to the aircraft.
Two Options to Disarm the Buzzer
Option 1, Disarm with button: Disconnect the main battery, hold disarm button on VIFLY Finder 2 for 1-5 seconds then release.
Option 2, Disarm with main battery: Disconnect the main battery, then connect the main battery for 3-6 seconds and disconnect it again.
It will beep 3 times when disarmed successfully.

Buyer's Guide: VIFLY Finder 2 Self-Powered FPV Drone Buzzer
Ever crashed your FPV drone or RC fixed-wing airplane into thick brush, high grass, or a remote field only to have the main LiPo battery pop off? Standard 5V buzzers instantly go silent when disconnected from power. The VIFLY Finder 2 solves this forever: it combines a high-decibel piezo buzzer, a self-charging internal LiPo battery, smart light-sensing LEDs, and universal PWM/FC compatibility to ensure you never lose a quad or plane again.
Here is your ultimate buyer’s guide covering real-world field-test performance, key features, and hardware setup instructions.
Real-World Field Test & Key Performance
● Highlights Ultra-Loud 110dB+ Alarm & 30+ Hours Runtime. Includes an integrated internal LiPo battery that charges automatically whenever your quad or plane is plugged in.
● Main Battery Ejection Recovery: If a crash ejects your main battery, the Finder 2 detects the power cutoff and automatically triggers its loud, high-pitched alarm for over 30 hours.
● 30-Second Grace Period: During the first 30 seconds after battery power is lost, it emits a low-volume beep, allowing you to re-plug or disarm the buzzer without deafening your ears at the bench. After 30 seconds, it ramps up to full 110dB+ peak volume.
Smart Light Sensor & Night Visuals
● Automatic Light Detection: Features a built-in optical light sensor. In dark conditions or thick bush cover, it flashes its ultra-bright white LED to guide you visually at dusk or night.
● Daylight Power Saving: Automatically turns off the LED during bright sunlight to conserve internal battery power for maximum buzzer runtime.
● Flight Controller Mode (Standard FC Setup): Connects via standard 5V, GND, and Buzzer- pads on any Betaflight, INAV, or Kiss flight controller. Functions as a traditional transmitter-triggered switch during normal flight.
● PWM Servo Mode (Fixed-Wing Planes): Connects directly to a receiver servo channel (via 3-pin PWM connector) without needing a flight controller. Pilots can trigger the alarm straight from a 3-position switch on their transmitter.

How to Disarm & Operate the VIFLY Finder 2
When you retrieve your crashed drone, turning off the alarm is simple:
Button Disarm: Press and hold the physical disarm/reset button on the side of the Finder 2 for 1–5 seconds.
LiPo Power Disarm: Re-plug your main quad LiPo battery for 1 to 4 seconds, then unplug it again. The Finder 2 will recognize the disarm cycle and remain silent.
Setup Tip: When installing the Finder 2, mount it where the side disarm button and the optical light sensor remain exposed to air/light. Avoid burying the light sensor beneath thick carbon plates so the night-flash LED functions correctly!
Is the VIFLY Finder 2 Worth It?
For around $13.99, the VIFLY Finder 2 is cheap insurance for any FPV quad or fixed-wing aircraft. One saved drone pays for this buzzer dozens of times over."
Buy VIFLY Finder 2 if: You fly high-speed freestyle, bando spots, long-range mountains, or fixed-wing RC planes where crashes risk ejecting the battery. It offers the loudest, most reliable lost-drone alarm on the market.
Q: Is the VIFLY Finder 2 mainly for racers, freestyle pilots, or long-range pilots?
A: It is useful for all three, but it becomes especially valuable on long-range, freestyle, and crash-prone builds where losing a quad in grass, trees, or rough terrain is a real risk.
Q: Is this buzzer really worth adding if my flight controller already has a normal buzzer?
A: Yes. Its biggest advantage is the built-in backup battery, so it can keep beeping even after the main LiPo is unplugged or ejected in a crash.
Q: Is the Finder 2 mainly about sound volume or about recovery reliability?
A: It offers both, but recovery reliability is the real reason to buy it. The self-powered design matters even more than the 110dB loudness.
Q: Is this a good accessory for pilots who fly in tall grass, woods, or mountain areas?
A: Yes. That is one of the clearest use cases. In places where a crashed quad is hard to see, a self-powered finder can save a lot of time and frustration.
Q: Does the Finder 2 make sense even on smaller FPV drones?
A: Yes, if recovering the quad matters more than saving every last gram. At about 5g, it is still light enough for many FPV builds.
