2.2 Assembly Steps
- Attach Search Coil: Secure the search coil to the lower stem using the provided bolt and washers. Ensure it is snug but do not overtighten.
- Assemble Stem: Connect the lower, middle, and upper stem sections. The stem is adjustable in length to suit user height.
- Mount Control Housing: Slide the control housing onto the upper stem. Ensure the coil cable is wrapped securely around the stem to prevent tangling and false signals.
- Install Arm Cuff: Attach the arm cuff to the upper stem, adjusting its position for comfortable use.
- Connect Coil Cable: Plug the search coil cable into the connector on the control housing. Ensure a tight, waterproof seal.
2.3 Battery Installation
The Garrett AT Pro requires AA batteries. Locate the battery compartment on the control housing, open it, and insert the batteries according to the polarity indicators. Close the compartment securely to maintain the waterproof seal.
3. Operating Instructions
Understanding the control panel and various modes is crucial for effective metal detection.
Figure 3.1: Detailed view of the Garrett AT Pro control panel, highlighting search modes, sensitivity, discrimination, and pinpoint controls.
3.1 Power On/Off
Press and hold the MODE button for 1 second to power on or off the detector.
3.2 Search Modes
The AT Pro offers six search modes: three Standard modes and three Pro modes. Use the MODE button to cycle through them.
- Standard Modes: Provide a simpler audio response, suitable for beginners.
- Pro Modes: Offer Proportional Audio and Tone Roll Audio, providing more nuanced target information for experienced users.
3.3 Sensitivity Adjustment
Adjust the detector's sensitivity using the SENSITIVITY buttons (+ and -). Higher sensitivity increases detection depth but may also increase susceptibility to electrical interference.
3.4 Iron Discrimination
The AT Pro features 40 levels of High-Resolution Iron Discrimination. Use the IRON DISC buttons (+ and -) to adjust the level at which iron targets are rejected. This helps in filtering out unwanted iron debris.
3.5 Pinpoint Mode
To precisely locate a detected target, press and hold the PINPOINT button. The audio response will intensify as the coil approaches the center of the target, allowing for accurate recovery.
3.6 Ground Balance
Ground balancing is essential for stable operation and maximum depth, especially in mineralized ground. Press and hold the GND BAL button and pump the coil up and down over the ground until the audio smooths out. The AT Pro offers both manual and automatic ground balance options.

3.7 Waterproof Operation
The Garrett AT Pro is fully submersible up to 10 feet (3 meters). Ensure all seals, especially the coil cable connection and battery compartment, are secure before submerging the detector. The included MS-2 headphones are also designed for use in wet environments.

3.8 Using MS-2 Headphones
Connect the MS-2 headphones to the detector's audio jack. These headphones are designed to enhance faint signals and reduce ambient noise, providing a clearer audio response from detected targets. They are also built to withstand wet conditions.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Garrett AT Pro.
- Cleaning: After each use, especially in wet or dirty conditions, wipe down the detector with a damp cloth. Avoid abrasive cleaners or solvents. For the search coil, rinse with fresh water if used in saltwater.
- Battery Care: Remove batteries if the detector will not be used for an extended period to prevent leakage. Always use fresh, high-quality batteries.
- Storage: Store the detector in a cool, dry place, away from extreme temperatures and direct sunlight. Ensure the coil cable is not kinked or stressed.
- Seal Inspection: Regularly inspect all O-rings and seals, particularly around the battery compartment and coil connection, to ensure they are free from dirt or damage that could compromise the waterproof integrity.
5. Troubleshooting
This section addresses common issues you might encounter with your Garrett AT Pro.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power | Dead or incorrectly installed batteries. | Replace batteries with fresh ones, ensuring correct polarity. Check battery compartment contacts. |
| Erratic Signals / False Signals | High mineralization, electrical interference, loose coil cable, or incorrect ground balance. | Perform ground balance. Reduce sensitivity. Ensure coil cable is tightly connected and wrapped. Move away from power lines or other electronic devices. |
| Poor Depth Detection | Incorrect ground balance, low sensitivity, or highly mineralized soil. | Re-ground balance. Increase sensitivity (if stable). Ensure proper coil sweep height. |
| Fuzzy/Malfunctioning Display | Moisture ingress, battery issue, or internal fault. | Ensure battery compartment is sealed. Check battery levels. If issue persists, contact Garrett customer support. |
