4. Operating Modes

Your Lepmerk Metal Detector offers four distinct operating modes to optimize your treasure hunting experience:

• ALL METAL Mode: In this mode, the detector will notify you when it senses any type of metal. It is ideal for general searching when you want to find all metallic objects without discrimination.
• DISC (Discrimination) Mode: This mode allows you to discriminate against unwanted types of metal. You can set the detector to ignore certain metals, focusing your search on specific targets like gold or silver.
• NOTCH Mode: Similar to DISC mode, NOTCH mode allows you to eliminate specific metal targets from detection. Press "NOTCH", then use the "+" or "-" buttons to select and eliminate the target ID you wish to ignore.
• PP (Pinpoint) Mode: Once you have detected a metal object, use PP mode to accurately identify its specific location. The closer you get to the metal target, the louder the audio tone produced by the detector, helping you pinpoint the exact spot for excavation.

Figure 4.1: Visual guide to the four main operating modes of the metal detector.

4.1. Three-Tone Audio Discrimination

The detector is equipped with three distinct audio tones (treble, midrange, and bass) that correspond to different types of metals. This feature assists in identifying the type of metal detected without looking at the display.

4.2. LCD Display and Backlight

The backlit LCD display provides crucial information at a glance, including possible metal types, target depth, DISC range, SENS level, volume, and battery condition, along with a digital display for target ID. Press the light button on the controller to turn the display backlight on or off, useful in dark environments.

5. Waterproof Features

The 10-inch search coil is IP68 waterproof, allowing for effective operation in shallow water environments such as beaches, streams, and during rainy conditions. This expands your treasure hunting possibilities significantly. Note: The control box is NOT waterproof and must be kept dry.

6. Maintenance

• Cleaning: After each use, especially in wet or dirty conditions, wipe down the search coil and rod with a damp cloth. Ensure the control box remains dry.
• Battery Care: If the metal detector will not be used for an extended period, remove the 9V batteries from the control box to prevent leakage and prolong battery life.
• Storage: Store the detector in its portable carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures.
• Cable Inspection: Periodically check all cables and connections for any signs of wear or damage.

7. Troubleshooting

If you encounter issues with your metal detector, please refer to the following common problems and solutions:

• No Power:
  • Check if batteries are correctly installed with proper polarity.
  • Ensure batteries have sufficient charge. Replace if necessary.
  • Verify all connections to the control box are secure.
• No Detection/Weak Signal:
  • Adjust the sensitivity (SENS) level.
  • Ensure the search coil cable is securely connected.
  • Check if you are in the correct operating mode (e.g., ALL METAL for general detection).
  • Perform a test with a known metal object to confirm functionality.
• False Signals/Chatter:
  • Lower the sensitivity (SENS) level.
  • Move away from sources of electromagnetic interference (power lines, other electronics).
  • Ensure the search coil cable is tightly wound around the rod and not swinging freely.
• Inaccurate Pinpointing:
  • Ensure you are in PP (Pinpoint) mode.
  • Slowly sweep the coil over the target area to identify the strongest signal.

If the problem persists, please contact customer support for further assistance.
