5. Setup
5.1 Assembling the MD04 Metal Detector
- Attach the search coil to the lower stem using the provided bolt and nut. Ensure it is securely fastened but do not overtighten.
- Connect the lower stem to the middle stem, and then connect the middle stem to the upper stem (which has the control box and armrest).
- Wrap the search coil cable neatly around the stem, ensuring it is not tangled, and plug the connector into the port on the control box.
- Adjust the stem length to a comfortable height that allows the search coil to be parallel to the ground when standing upright. Secure the adjustment locks.
- Insert the required batteries into the battery compartment located on the control box. Ensure correct polarity.
5.2 Installing Batteries for MD08 Pinpointer
- Unscrew the battery cap at the end of the pinpointer.
- Insert a 9V battery, observing the correct polarity (+/-).
- Screw the battery cap back on tightly to ensure the waterproof seal is maintained.
6. Operating the MD04 Metal Detector
6.1 Power On/Off
Press and hold the POWER button to turn the detector on or off.
6.2 Operating Modes
The MD04 offers several detection modes to suit different searching conditions and target preferences. Use the MENU button to cycle through modes and the + / - buttons to adjust settings within each mode.
- ALL METAL Mode: Detects all types of metal objects. This mode offers the deepest detection depth.
- DISC (Discrimination) Mode: Allows you to eliminate certain types of metal from detection, such as iron, to focus on more valuable targets.
- NOTCH Mode: Similar to DISC, but allows you to selectively "notch out" specific ranges of metal conductivity.
- PINPOINT Mode: Press the PINPOINT button to activate. This mode helps to precisely locate the exact position of a detected target before digging. The detector will emit a continuous tone that increases in pitch and volume as you get closer to the target.
6.3 Sensitivity Adjustment (SENS)
Adjust the sensitivity using the + / - buttons in the menu. Higher sensitivity increases detection depth but may also increase false signals in mineralized ground. Start with a moderate sensitivity and adjust as needed.
6.4 Volume Adjustment (VOLUME)
Adjust the audio volume of the detector using the + / - buttons in the menu.
6.5 Target Identification and Depth
The LCD display provides visual cues for target identification (Target ID) and estimated depth (Coin Depth Indicator). Different target IDs correspond to different types of metal.

7. Operating the MD08 Pinpointer
7.1 Power On/Off
Press the one-touch switch button to turn the pinpointer on. Press and hold the button to turn it off.
7.2 Detection and Alert Modes
The MD08 pinpointer offers 360-degree detection and provides multiple alert types when metal is detected.
Image 7.2.1: Icons representing the four types of reflections/alerts provided by the MD08 pinpointer: Sound, Vibration, Light (LED), and Screen (LCD display for signal strength).
- Buzzer: Emits an audible "Beep Beep" sound.
- Vibration: The device will vibrate.
- Sound: An audible tone.
- LCD Screen: The signal strength will be displayed on the LCD screen, increasing as you get closer to the target. The LED light will also strobe.
7.3 Pinpointing Technique
Once the main detector has identified a target area, use the MD08 pinpointer to narrow down the exact location. Move the tip of the pinpointer slowly over the area. The alerts will intensify as you approach the target.

8. Maintenance
- Cleaning: After each use, wipe down the detector and pinpointer with a damp cloth. Avoid using abrasive cleaners or solvents.
- Storage: Store the devices in a cool, dry place when not in use. If storing for extended periods, remove all batteries to prevent leakage.
- Coil Care: The MD04 search coil is waterproof and can be rinsed with fresh water. Ensure the cable connection to the control box is dry before re-connecting.
- Pinpointer Care: The MD08 pinpointer is fully waterproof and can be rinsed. Ensure the battery cap is tightly sealed before exposing to water.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector not powering on. | Low or dead batteries; incorrect battery polarity. | Replace batteries; check battery orientation. |
| Excessive false signals (MD04). | High sensitivity setting; highly mineralized ground; electromagnetic interference. | Reduce sensitivity; try a different detection mode (DISC/NOTCH); move away from power lines or other electronics. |
| No detection or weak detection. | Low batteries; sensitivity too low; search coil not properly connected. | Replace batteries; increase sensitivity; ensure search coil cable is securely plugged in. |
| Pinpointer not detecting. | Low or dead battery; pinpointer not turned on. | Replace 9V battery; press the power button to activate. |
