Setup and Assembly
Follow these steps to assemble your Gold Hunter Metal Detector:
- Attach the Search Coil: Connect the search coil to the lower stem using the provided bolt and knob. Ensure it is securely fastened but not overtightened.
- Connect the Stems: Insert the lower stem into the middle stem, and then the middle stem into the upper stem. Adjust the length to a comfortable height using the locking collars.
- Mount the Control Box: Slide the control box onto the upper stem. Secure it in place.
- Wrap the Cable: Carefully wrap the search coil cable around the stem, ensuring it is snug but not stretched. Plug the cable connector into the corresponding port on the control box.
- Install Batteries: Open the battery compartment (usually located on the control box or under the armrest) and insert the required batteries, observing correct polarity. This model operates on a rechargeable battery.

Operating Instructions
Powering On and Off
- To turn on the detector, locate the power button/knob on the control box and switch it to the 'ON' position.
- To turn off the detector, switch the power button/knob to the 'OFF' position.
Adjusting Sensitivity
The Sensitivity Control allows you to adjust the detector's responsiveness to targets. Higher sensitivity settings can detect smaller or deeper objects but may also pick up more ground noise or interference.
- Increase Sensitivity: Turn the sensitivity knob clockwise (or press the '+' button) to increase detection depth.
- Decrease Sensitivity: Turn the sensitivity knob counter-clockwise (or press the '-' button) to reduce false signals, especially in highly mineralized ground or areas with electrical interference.
Discrimination Mode
The discrimination feature allows the detector to ignore certain types of metal, typically iron (ferrous metals), while still detecting more valuable non-ferrous metals like gold, silver, and copper.
- Setting Discrimination: Use the discrimination control (knob or buttons) to set the level at which unwanted metals are rejected. A higher discrimination setting will filter out more types of junk metal.
- All-Metal Mode: For maximum depth and to detect all types of metal, set the discrimination to its lowest level or select the 'All-Metal' mode if available.
Sweeping Technique
Proper sweeping technique is crucial for effective detection:
- Hold the search coil parallel to the ground, about 1-2 inches above the surface.
- Sweep the coil from side to side in a slow, overlapping motion.
- Maintain a consistent speed and height for best results.
- When a target is detected, the detector will emit an audible tone, and the display (if present) may indicate the type of metal.
Maintenance
- Cleaning: Wipe down the detector with a damp cloth after each use. Do not use abrasive cleaners or solvents. The search coil can be rinsed with water, but ensure the control box remains dry.
- Storage: Store the detector in a cool, dry place when not in use. If storing for an extended period, remove the rechargeable battery to prevent leakage.
- Battery Care: Recharge the battery fully before storage and periodically during long storage periods to maintain battery health.
- Cable Inspection: Regularly check the search coil cable for any signs of wear or damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Battery not charged or incorrectly installed. | Ensure rechargeable battery is fully charged and correctly inserted. |
| Constant false signals (chattering) | High sensitivity setting, electrical interference, or highly mineralized ground. | Reduce sensitivity. Move away from power lines or other electronic devices. Adjust discrimination. |
| Poor detection depth | Low sensitivity setting, incorrect sweeping technique, or deeply buried target. | Increase sensitivity. Ensure search coil is parallel to the ground and swept slowly. |
| Detector beeps on non-metal objects | Discrimination set too low. | Increase discrimination level to filter out unwanted targets. |
