3. Setup and Assembly
Follow these steps to assemble your Tracker IV Metal Detector:
- Attach the Search Coil: Secure the 8-inch search coil to the lower stem using the provided bolt and wing nut. Ensure the coil cable is wrapped snugly around the stem.
- Connect the Stems: Connect the lower stem to the middle stem, and then the middle stem to the upper stem (control housing). The adjustable shaft allows for quick release and length adjustment.
- Mount the Control Housing: Slide the control housing onto the upper stem. Ensure it is securely fastened.
- Adjust Armrest: Position the padded armrest for comfortable use. The armrest is adjustable for different arm lengths.
- Install Batteries: Open the battery compartment on the control housing and insert two 9V alkaline batteries. Ensure correct polarity.
- Connect Headphones (Optional): If using headphones, plug them into the 1/4-inch headphone jack on the control panel.

4. Operating Modes
The Tracker IV offers three primary detection modes:
- All Metal Mode: Detects all types of metal. This mode offers the greatest depth detection and is ideal for general searching or when you are unsure of the target type.
- Tone Mode: Provides different audio tones for various metal types, helping you distinguish between valuable targets and junk.
- Discrimination Mode: Allows you to eliminate unwanted metals (junk) from detection. You can adjust the discrimination level to ignore specific types of metal, such as iron or foil.

5. Sensitivity and Discrimination Controls
The control panel features two main knobs:
- Sensitivity Control: Adjusts the detector's ability to pick up signals. Higher sensitivity increases detection depth but may also increase false signals in mineralized ground or areas with high electrical interference. Start with a medium setting and adjust as needed.
- Discrimination Control (DISC/NOTCH): This control allows you to filter out unwanted metals. Turning the knob clockwise increases the level of discrimination, ignoring more types of junk metal. Use this to focus on specific valuable targets like coins or jewelry.
6. Pinpointing Targets
Once a target is detected, pinpointing helps locate its exact position before digging:
- Narrow the Search: Slowly sweep the coil over the target area in a crisscross pattern, listening for the strongest signal.
- Reduce Sensitivity: Lower the sensitivity temporarily to narrow the detection field.
- Use the Digger: Once the target location is narrowed, use the included digger to carefully excavate the item. The digger is designed for efficient and precise recovery.

7. Maintenance and Care
To ensure the longevity and optimal performance of your metal detector:
- Cleaning: Wipe down the detector with a damp cloth after each use. Avoid abrasive cleaners.
- Battery Care: Remove batteries if the detector will not be used for an extended period to prevent leakage. Replace batteries when the low battery indicator appears.
- Storage: Store the detector in a cool, dry place. The included carry pouch is ideal for protecting the unit during transport and storage.
- Coil Protection: The 8-inch search coil is waterproof, but the control housing is not. Avoid submerging the control housing.

8. Troubleshooting
If you encounter issues with your Tracker IV, try these common solutions:
- No Power: Check battery installation and ensure batteries are fresh.
- Erratic Signals/False Signals: Lower the sensitivity setting. Ensure the search coil cable is tightly wound around the stem and securely connected. Avoid areas with strong electromagnetic interference (power lines, other electronics).
- No Detection: Ensure the detector is turned on and the search coil is properly connected. Check that the discrimination level is not set too high, potentially filtering out desired targets.
- Weak Signal: Increase sensitivity. Ensure the search coil is parallel to the ground during sweeps.
