Maintenance

• Cleaning: After each use, especially in wet or sandy conditions, clean the search coil with fresh water. Wipe down the control box and shaft with a damp cloth. Ensure the control box is dry before storage.
• Storage: Store the metal detector in a cool, dry place. Disassemble the shaft for compact storage in the provided backpack.
• Battery Care: Fully charge the battery after each use to prolong its lifespan. Avoid completely draining the battery frequently.

Troubleshooting

Q1: Why Does The Detector Just Beeps All The Time?

This can be caused by high sensitivity settings or electromagnetic interference.

• Solution: Lower the sensitivity setting. Move away from other electronic devices (smartphones, power lines, etc.). Ensure the search coil cable is wrapped tightly around the shaft.

Video: Troubleshooting common issues like continuous beeping, explaining causes and solutions for the metal detector.

Q2: Why Using Pinpoint Mode Didn’t Help You Find Anything?

Pinpoint mode requires a brief calibration period after activation.

• Solution: After pressing the PP button, wait 2-3 seconds for the PP indicator on the screen to stop flashing before moving the coil. This allows the detector to calibrate the magnetic field between the coil and the ground. If you start searching too soon or if metal is too close during calibration, the detector might try to balance out that interference, making it miss the actual target.

Video: Explaining why pinpoint mode might not work and how to properly use it for accurate target location.

Q3: Why is the detector giving false signals?

False signals can be caused by highly mineralized ground, loose cable connections, or physical interference.

• Solution: Adjust sensitivity in mineralized areas. Check that all cable connections are secure. Avoid hitting branches or rocks with the search coil. Ensure no metal objects are on your person (keys, jewelry, belt buckles, etc.) that could interfere.
