5. Sensitivity and Discrimination
Adjust sensitivity using the SENS DISC buttons to optimize depth and minimize false signals. Use discrimination settings to ignore unwanted trash items (e.g., iron) while still detecting valuable targets.
6. Pinpoint Mode
Activate Pinpoint mode by pressing the RETUNE / PINPOINT button to precisely locate the target before digging, reducing recovery time and minimizing ground disturbance.
Maintenance
To ensure the longevity and optimal performance of your Garrett ATX Deepseeker, follow these maintenance guidelines:
- Cleaning: After each use, wipe down the detector, especially the search coil, with a damp cloth to remove dirt, mud, or saltwater residue. Avoid using abrasive cleaners.
- Storage: Store the detector in a cool, dry place. For long-term storage, remove the batteries to prevent leakage. Utilize the provided soft storage/travel case or the military-grade hard case for protection during transport and storage.
- Cable Care: Regularly inspect the search coil cable for any signs of wear or damage. Ensure it is not kinked or pinched.
- Battery Care: Always use fresh, high-quality batteries. If using rechargeable batteries, follow the charging instructions carefully.
Troubleshooting
If you encounter issues with your ATX Deepseeker, consider the following common troubleshooting steps:
- No Power: Check battery installation and ensure batteries are fully charged.
- Erratic Signals/False Signals: Perform a ground balance. Reduce sensitivity. Check for electromagnetic interference from power lines or other electronic devices. Ensure search coil cable is securely connected and not damaged.
- No Target Response: Increase sensitivity. Ensure the search coil is properly connected. Check that discrimination settings are not too high, potentially filtering out desired targets.
- Weak Signals: Check battery level. Ensure sensitivity is set appropriately for ground conditions.
For more complex issues, refer to the detailed troubleshooting section in your complete user manual or contact Garrett customer support.
