5. Assembly and Setup
The SUNPOW OT-MD15 Metal Detector features a tool-free assembly process, allowing for quick setup.
- Attach the Search Coil: Secure the 11-inch Dual-D search coil to the lower stem using the provided non-metallic bolt and wing nut. Ensure it is firmly attached but do not overtighten.
- Connect the Shaft Sections: Insert the lower stem into the middle stem, and then the middle stem into the upper stem (which includes the control unit and armrest).
- Adjust Shaft Length: Loosen the locking collars on the shaft. Adjust the length of the shaft to a comfortable position, typically where the search coil can be swept parallel to the ground while standing upright. The shaft can extend from 19 inches to 51 inches. Once adjusted, tighten the locking collars to secure the length.
- Secure the Cable: Wrap the search coil cable snugly around the shaft, ensuring it is not loose or dangling. Plug the coil connector into the corresponding port on the control unit.
- Adjust Armrest: Position the armrest for comfortable use, providing support during extended detection sessions.

6. Operating Instructions
The SUNPOW OT-MD15 offers four distinct search modes and adjustable sensitivity for optimal performance.
6.1 Power On/Off
Press and hold the power button on the control unit to turn the detector on or off.
6.2 Sensitivity Adjustment
Use the 'SENS' button to adjust the sensitivity level. Higher sensitivity increases detection depth but may also increase false signals in highly mineralized ground. Start with a moderate setting and adjust as needed.
6.3 Search Modes
The detector features four professional search modes:
- All Metal (AM) Mode: Detects all types of metal objects. This mode offers the greatest depth and is ideal for general searching when you want to find any metal.
- Discrimination (Disc) Mode: Allows you to eliminate unwanted metal types (junk metals) from detection. Use the 'DISC' button to adjust the discrimination level, focusing on specific target types like coins or jewelry.
- Notch Mode: Similar to Discrimination, but allows for specific rejection of certain metal categories while accepting others. This provides more precise control over target identification.
- Pinpoint (PP) Mode: Once a target is detected, switch to Pinpoint mode to accurately locate the exact position of the buried object. This mode helps reduce digging time and effort.

7. Battery Charging and Care
The SUNPOW OT-MD15 is equipped with a built-in 2500mAh rechargeable lithium battery.
- Charging: Connect the provided USB charging cable to the charging port on the control unit and plug the other end into a standard USB power adapter (not included) or a computer USB port. The charging indicator will show the charging status.
- Battery Life: A full charge provides approximately 35 hours of operation.
- Storage: For long-term storage, ensure the battery is charged to about 50-70% to maintain battery health. Recharge every 3-6 months if not in use.
- Avoid Over-Discharge: Do not allow the battery to completely drain frequently, as this can reduce its lifespan.

8. Maintenance
- Cleaning: After each use, wipe down the detector with a damp cloth. Ensure the control unit is dry. The search coil can be rinsed with fresh water if used in saltwater or muddy conditions.
- Storage: Store the metal detector in a cool, dry place, away from direct sunlight and extreme temperatures. Disassemble the shaft for compact storage in the provided carrying bag.
- Cable Inspection: Periodically check the search coil cable for any signs of wear or damage.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on. | Low or depleted battery. | Charge the battery fully. |
| Erratic signals or false positives. | High sensitivity setting, electromagnetic interference, or highly mineralized ground. | Reduce sensitivity. Move away from power lines or other electronic devices. Use Discrimination or Notch mode. |
| No detection or weak signals. | Low sensitivity, incorrect mode, or loose coil connection. | Increase sensitivity. Ensure All Metal mode is selected for general searching. Check that the search coil cable is securely connected. |
| Pinpoint mode is inaccurate. | Incorrect technique. | Sweep the coil slowly over the target in a cross-pattern to narrow down the location. |
