Operating Instructions
1. Power On/Off
- To power on: Press and hold the power button until the device activates.
- To power off: Press and hold the power button until the device deactivates.
2. Calibration
Upon powering on, the PRO-FIND 20 will perform an automatic calibration. Ensure the pinpointer is held away from any metal objects during this process for accurate calibration.
3. Detection Indication (Audio & Vibration)
The PRO-FIND 20 provides both audio tones and vibrations to indicate the presence of metal. As the probe approaches a target, the audio tones will intensify and the vibration will increase, helping to pinpoint the exact location.

4. Lost Alarm
If the PRO-FIND 20 is left inactive for a period, a lost alarm will sound to help you locate it, especially useful in low light or tall grass.
5. DIF Technology
The Detector Interference Free (DIF) technology disengages the pinpointer coil's magnetic field when switched off, significantly reducing interference with an operating metal detector.
