2. Setup
2.1 Assembly
Follow these steps to assemble your Teknetics Delta 4000 Metal Detector:
- Attach the Search Coil: Secure the 8-inch waterproof search coil to the lower stem using the provided bolt and wing nut. Ensure it is firmly attached but can still pivot.
- Connect the Lower and Middle Stems: Insert the lower stem into the middle stem and secure it with the spring clip or locking collar.
- Connect the Upper Stem and Control Box: Slide the control box onto the upper stem. Adjust the length of the stem to a comfortable height, then secure it.
- Wrap the Cable: Carefully wrap the search coil cable around the stem, ensuring it is not too tight or loose, and plug the connector into the control box.
- Attach the Armrest: Secure the armrest to the upper stem for comfortable operation.

2.2 Battery Installation
The Delta 4000 requires one 9-volt alkaline battery for operation. Ensure the battery is fresh for optimal performance.
- Locate the battery compartment on the back of the control box.
- Open the battery cover by sliding or unlatching it.
- Insert a new 9-volt battery, observing the correct polarity (+/-) as indicated inside the compartment.
- Close the battery cover securely.
3. Operating Instructions
3.1 Powering On/Off
Press and hold the POWER button (usually marked with a power symbol) on the control panel to turn the detector on or off. The LCD display will illuminate upon power-on.
3.2 Understanding the Display
The large LCD display provides crucial information during your search:

- Target ID: A two-digit number (00-99) indicating the probable identity of the detected metal. Higher numbers generally correspond to more conductive metals like silver, while lower numbers indicate iron or foil.
- Depth Indicator: Estimates the depth of the target.
- Battery Status: Shows the remaining battery life.
- Mode Indicator: Displays the current operating mode (e.g., ALL METALS, DISCRIMINATE, PINPOINT).
- Discrimination Segments: Icons representing different metal types (e.g., IRON, FOIL, 5¢, ALUM, ZINC, DIME, QTR, 50¢+) that can be discriminated against.
3.3 Modes of Operation
Use the MODE button to cycle through the available detection modes:
- Discriminate Mode: This is the primary search mode. It allows you to filter out unwanted metals (junk) based on your discrimination settings.
- All Metals Mode: Detects all types of metal without discrimination. Useful for finding deeply buried targets or when you want to detect everything.
- Pinpoint Mode: Press the PINPOINT button to narrow down the exact location of a detected target. The audio tone will peak and the depth indicator will become more precise as you center the coil over the target.
3.4 Adjusting Settings
Use the MENU button to access settings and the + and - buttons to adjust values.
- Sensitivity: Controls the detector's ability to detect small or deep targets. Increase for more depth, decrease to reduce false signals in noisy environments.
- Discrimination Level: Adjusts which metal types the detector will ignore. Higher levels will filter out more junk metals.
- Notch: Allows you to selectively ignore specific target ID ranges.
- Volume: Adjusts the audio output level.
3.5 Ground Balancing
The Delta 4000 features automatic ground balancing. This function continuously adjusts to the mineralization of the soil, ensuring stable operation and accurate target identification. No manual adjustment is typically required for this model.

4. Maintenance
Proper maintenance will extend the life and performance of your metal detector.
- Cleaning: After each use, wipe down the control box and stem with a damp cloth. The search coil is waterproof and can be rinsed with fresh water. Avoid using abrasive cleaners or solvents.
- Storage: Store the detector in a dry, cool place. If storing for an extended period, remove the 9-volt battery to prevent leakage and corrosion.
- Cable Care: Ensure the search coil cable is not kinked or pinched, as this can damage the internal wiring.
5. Troubleshooting
If you encounter issues with your Teknetics Delta 4000, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on. | Dead or incorrectly installed battery. | Replace the 9-volt battery, ensuring correct polarity. |
| Excessive false signals or chatter. | High sensitivity setting, electromagnetic interference, or highly mineralized ground. | Reduce sensitivity. Move away from power lines or other electronic devices. The automatic ground balance should compensate for mineralization, but extreme conditions may require sensitivity reduction. |
| No detection or weak signals. | Search coil cable loose, discrimination set too high, or target too deep. | Check search coil cable connection. Reduce discrimination level. Increase sensitivity if appropriate for conditions. |
| Inaccurate target ID. | Multiple targets, target partially discriminated, or target at edge of detection field. | Sweep slowly and try pinpoint mode. Adjust discrimination if necessary. |
