3. Assembly

Follow these steps to assemble your MD-3010H Metal Detector. No special tools are required.

1. Install Batteries: Open the battery compartment on the control box. Insert two 9V (6F22, S006P) batteries, ensuring correct polarity. Close the compartment securely.
2. Attach Control Box to Upper Stem: Slide the control box onto the upper stem. Secure it by tightening the knob on the side of the control box.
3. Connect Search Coil to Lower Stem: Attach the search coil to the lower stem using the provided screw and washers. Ensure it is firmly secured but allows for angle adjustment.
4. Assemble Stem Sections: Connect the middle stem to the lower stem, and then connect the upper stem (with the control box) to the middle stem. The sections should snap or screw together.
5. Route Cable: Wrap the search coil cable neatly around the stem, ensuring it is not taut or loose. Plug the cable connector into the corresponding port on the control box.
6. Adjust Length: Adjust the stem length to a comfortable position for your height (adjustable from 102cm/3.3ft to 130cm/4.2ft). Secure the adjustment.
7. Attach Armrest: Ensure the armrest is correctly positioned for comfortable use.

5. Operation

Before operating, ensure the detector is fully assembled and batteries are installed.

5.1 Power On/Off and Volume

Rotate the Power/Volume knob clockwise to turn the detector ON. Continue rotating to increase volume. Rotate counter-clockwise to decrease volume and turn OFF.

5.2 Sensitivity Adjustment (SENS)

Press the MENU button until 'SENS' appears on the display. Use the +/- buttons to adjust sensitivity. Higher sensitivity increases detection depth but may also increase false signals in mineralized ground.

5.3 Discrimination (DISC) and Notch

The detector can discriminate between different metal types. Use the DISC setting to ignore unwanted metals (e.g., iron). The NOTCH function allows you to selectively eliminate specific target categories. The LCD display will show the type of metal detected (e.g., IRON, 5¢, P-TAB, 10¢, 25¢, 50¢, 1$).

5.4 Pinpointing (PP)

Once a target is detected, press and hold the PP button to activate pinpoint mode. Move the search coil slowly over the target area. The detector will emit a continuous tone and the signal strength indicator will increase as you get closer to the exact center of the target.

5.5 Waterproof Search Coil

The search coil is waterproof, allowing for detection in shallow water. Ensure the control box and connections remain dry as they are not waterproof.

6. Maintenance

• Keep the detector clean and dry. Wipe down the search coil and stem after use, especially after detecting in wet or sandy conditions.
• Avoid exposing the control box to extreme temperatures or direct sunlight for prolonged periods.
• Remove batteries if the detector will not be used for an extended period to prevent leakage.
• Store the detector in a safe place, preferably in its carrying case, to prevent damage.

7. Troubleshooting

• No Power: Check battery installation and ensure batteries are fresh.
• Erratic Signals: Reduce sensitivity. Ensure the search coil cable is tightly wrapped and connected. Avoid detecting near power lines or other electronic devices.
• No Target Indication: Increase sensitivity. Ensure the search coil is parallel to the ground and moving at a consistent speed.
• Headphones Not Working: Check headphone connection to the PHONE jack. Ensure volume is adjusted.
