5. Operating Modes
The KENTOKTOOL Metal Detector TX-4071 features three distinct operating modes to suit various detection needs:
- All Metal Mode: Detects all types of metal without discrimination. This mode offers the deepest penetration and is ideal for general searching when you want to find any metallic object.
- DISC Mode (Discrimination Mode): Allows you to eliminate unwanted metal targets (e.g., iron, foil) and focus on more valuable items. The LCD display will indicate the probable type of metal detected.
- Pinpoint Mode: Used to accurately locate the exact position of a detected target. Once a target is found in All Metal or DISC mode, switch to Pinpoint mode to narrow down its location for easier retrieval.

6. Basic Operation
- Power On: Press the power button on the control box to turn on the detector.
- Select Mode: Use the "MODE" button to cycle through All Metal, DISC, and Pinpoint modes.
- Adjust Sensitivity: Use the "+" and "-" buttons to adjust the sensitivity. Higher sensitivity increases detection depth but may also increase false signals.
- Sweep the Coil: Hold the detector with the search coil parallel to the ground, about 1-2 inches above the surface. Sweep the coil slowly from side to side in overlapping arcs.
- Interpret Signals: The LCD display will show target ID and approximate depth. Audio tones will also indicate the presence and type of metal.
- Pinpoint Target: Once a target is detected, switch to Pinpoint mode. Move the coil slowly over the area until the strongest and most stable signal is heard/seen, indicating the target's center.

7. Adjustments
- Sensitivity: Adjust using the "+" and "-" buttons. Start with a medium setting and increase if needed for deeper targets, or decrease if experiencing excessive false signals.
- Volume: Control the audio output volume through the settings menu.
- Notch: In DISC mode, the Notch function allows you to selectively ignore specific ranges of metal types. Refer to the LCD display for target ID ranges.
- Backlight: The LCD display features a backlight for improved visibility in low-light conditions. Activate it via the settings.
- Adjustable Stem: The stem length can be adjusted to accommodate users of different heights, ensuring comfortable operation.

8. Maintenance
- Cleaning: Wipe the search coil and stem with a damp cloth after each use, especially after use in saltwater or sandy environments. Keep the control box clean and dry.
- Storage: Store the metal detector in a cool, dry place when not in use. If storing for extended periods, remove the batteries to prevent leakage.
- Battery Care: Replace batteries when the low battery indicator appears on the LCD. Always use fresh, high-quality 9V batteries.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Dead or incorrectly installed batteries | Replace batteries or ensure correct polarity. |
| False signals/Chattering | High sensitivity, electromagnetic interference, mineralized ground | Reduce sensitivity, move away from power lines/electronics, try ground balancing (if available). |
| Poor detection depth | Low sensitivity, small target, deeply buried target | Increase sensitivity, sweep slower, ensure coil is parallel to ground. |
| Inaccurate target ID | Multiple targets, target orientation, mineralized ground | Sweep from different angles, use Pinpoint mode, adjust discrimination. |
