4. Assembly
Follow these steps to assemble your metal detector:
- Attach the Search Coil: Connect the 11-inch waterproof search coil to the lower stem. Ensure it is securely fastened.
- Connect the Stems: Insert the lower stem into the middle stem, and then the middle stem into the upper stem. Secure them using the quick-release clips.
- Mount the Control Box: Slide the control box onto the upper stem and secure it in place.
- Wrap the Cable: Carefully wrap the search coil cable around the stem, ensuring it is not too tight or loose, and plug it into the control box.
- Attach Armrest: Secure the armrest to the upper stem for comfortable operation.

5. Setup
- Battery Installation: Open the battery compartment on the control box and insert the two 9V batteries, ensuring correct polarity. Close the compartment securely.
- Adjust Stem Length: Adjust the stem length from 41 to 52 inches using the quick-release clips to a comfortable height that allows you to sweep the coil parallel to the ground without bending excessively.
- Adjust Armrest: Position the armrest for optimal comfort and stability during use. The non-slip handle design helps reduce fatigue during long detection sessions.
- Headset Connection: Plug the high-quality headset into the 3.5mm jack on the control box for clear audio signals.
6. Operating Modes
The SMD02 features 5 multifunctional detecting modes and additional settings for precise treasure hunting:
- All Metal Mode:
This mode detects all types of metal. The detector will notify you whenever it detects any metal, regardless of its type. Ideal for general searching when you want to find everything.

The LCD display indicating 'ALL METAL MODE', which detects lead, bronze, iron, gold, silver, coins, tin, aluminum, and other metal objects.
- Disc & Notch Mode:
This mode helps discriminate unwanted metal types. You can adjust the settings to ignore specific metals (e.g., iron, bottle caps) and focus on more valuable targets. The Notch function allows you to selectively eliminate certain conductivity ranges.

- Pinpoint Mode:
Once a target is detected, activate Pinpoint Mode to accurately locate its exact position. This helps in minimizing digging and precisely extracting the item.

- Memory Mode:
This mode retains all settings from your last use. Additionally, you can use it to memorize a specific target's signature and then search exclusively for that type of object, filtering out all others.

- SENS Mode:
Adjust the level of sensitivity to detect the metal you want. Higher sensitivity can detect smaller or deeper objects, but may also pick up more interference. Adjust as needed for your environment.

- Backlight:
The intuitive LCD display includes an adjustable backlight, which is greatly helpful for searching in dark situations or at night.

- Numeric Ranges of Target Indications:
The LCD screen provides numeric ranges to help identify the type of metal detected:
Range Metal Type 00-10 Iron, Iron Scap, or Iron Relic 11-20 5¢ or a Nickel 21-40 P-TAB (Pull Tab) 41-60 1¢ or type of metal of zinc alloy 61-75 10¢ or large rough gold items 76-99 25¢ or a silver coin

7. Operation Tips
- Sweeping Technique: Hold the search coil parallel to the ground, about 1 to 2 inches off the surface. Sweep the coil slowly from side to side in overlapping arcs. Avoid lifting the coil at the end of each sweep.
- Ground Balance: The detector automatically adjusts to ground conditions. If you experience excessive false signals, try reducing the sensitivity.
- Target Identification: Pay attention to the audio tones and the numeric display on the LCD screen to help identify potential targets before digging.
- Waterproof Coil: The 11-inch search coil is waterproof, allowing for detection in shallow water, beaches, streams, and rivers. Note: The control box is NOT waterproof.

8. Maintenance
- Cleaning: After each use, wipe down the search coil and stem with a damp cloth. Ensure the control box remains dry.
- Storage: Store the metal detector in a cool, dry place. If storing for an extended period, remove the batteries to prevent leakage.
- Battery Care: Replace batteries when the low battery indicator appears on the LCD. Use high-quality 9V batteries for optimal performance.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Dead or incorrectly installed batteries | Replace batteries with new 9V batteries, ensuring correct polarity. |
| False signals/Chattering | High sensitivity, electromagnetic interference, mineralized ground | Reduce sensitivity (SENS Mode). Move away from power lines or other electronic devices. Use DISC/NOTCH mode to filter out unwanted signals. |
| No detection | Low sensitivity, coil not sweeping correctly, target too deep | Increase sensitivity. Ensure the coil is swept slowly and parallel to the ground. Check if the target is within the detection depth. |
| Inaccurate target ID | Multiple targets, target size/shape, ground mineralization | Use Pinpoint Mode for precise location. Adjust DISC/NOTCH settings. Practice with known targets to understand ID responses. |
