JHEMCU JHE42B Self-Powered FPV Drone Finder with 110dB Buzzer & LED

Never Lose Your Drone Again!

The JHEMCU JHE42B Finder is an essential piece of equipment for any FPV pilot. This compact and lightweight device ensures you can locate your quadcopter after an unexpected crash, even if the main battery has been ejected. With a deafening 110dB alarm and a bright, flashing LED, the JHE42B makes finding your lost drone quick and easy, saving you time, money, and stress.

This smart buzzer features its own integrated battery, allowing it to operate independently from your drone's main power source. It automatically activates 30 seconds after a power loss, giving you peace of mind during every flight.

Key Features:

• Extremely Loud Alarm: Emits a powerful 110dB sound, audible from a significant distance.
• Self-Powered: Includes a built-in 100mAh LiPo battery that charges automatically during flight. Works for up to 30 hours on a single charge.
• Bright LED Light: A flashing white LED provides a visual aid, perfect for finding your drone in low-light conditions or tall grass.
• Dual Operation Modes: Functions as a standard flight controller buzzer during normal operation and switches to self-powered finder mode upon main battery disconnection.
• Easy Installation: Simply connect it to your flight controller's buzzer pads. It's compatible with all Betaflight and Cleanflight controllers.
• Simple Disarm: To turn off the alarm, press and hold the button for more than 2 seconds.
