Always follow the manufacturer's instructions for safe usage and storage.

3. Setup and Assembly

Follow these steps to assemble your Garrett ATX metal detector.

3.1 Attaching the Search Coil

1. Align the search coil with the lower stem.
2. Insert the coil bolt through the holes and secure with the wing nut. Do not overtighten.
3. Wrap the coil cable snugly around the lower and middle stems, ensuring it is not loose or dangling.
4. Connect the coil cable connector to the control housing, ensuring a secure, watertight connection.

3.2 Adjusting the Stem Length

1. Loosen the cam locks on the stem sections.
2. Adjust the stem to a comfortable length that allows the search coil to be parallel to the ground when sweeping. The detector has an extended length of up to 68 inches.
3. Tighten the cam locks securely to prevent movement during operation.

3.3 Battery Installation

The ATX operates on AA batteries. Both alkaline and rechargeable batteries are included.

1. Locate the battery compartment on the control housing.
2. Open the compartment and insert the batteries, ensuring correct polarity (+/-).
3. Close the compartment securely to maintain its waterproof seal.
4. To charge rechargeable batteries, remove them and use the provided external charger.

3.4 Connecting Headphones

Connect the land headphones to the designated port on the control housing. Ensure the connection is firm.

4. Operating Instructions

Familiarize yourself with the control panel and its functions for optimal performance.

4.1 Control Panel Overview

Figure 4.1: The Garrett ATX control panel, showing buttons for Sensitivity/Discrimination, Motion/Non-Motion, Iron Check, Threshold/Volume, and Retune/Pinpoint.

• SENS/DISC: Adjusts sensitivity and discrimination levels.
• NON-MOTION/MOTION: Toggles between search modes.
• IRON CK (HOLD): Checks for iron content in a target.
• THRESH/VOL: Adjusts audio threshold and volume.
• RETUNE/PINPOINT: Resets the detector or provides precise target location.
• GND BAL (HOLD) / GND TRACK: Initiates ground balance or enables ground tracking.

4.2 Powering On/Off

Press and hold the power button (usually integrated with the volume knob or a dedicated button) until the unit powers on or off. The LED display will illuminate upon startup.

4.3 Ground Balance

Ground balancing is crucial for stable operation, especially in mineralized soils.

1. Hold the coil about 1 foot above the ground.
2. Press and hold the GND BAL button.
3. Pump the coil up and down from 1 inch to 1 foot above the ground.
4. Release the button when the audio signal stabilizes.
5. For continuous adjustment, activate GND TRACK mode.

4.4 Search Modes

• Motion Mode: Requires the coil to be in motion to detect targets. Offers discrimination capabilities.
• Non-Motion Mode: Detects targets when the coil is stationary over them. Useful for pinpointing or searching in confined spaces.

Toggle between modes using the NON-MOTION/MOTION button.

4.5 Sensitivity and Discrimination

• Use the SENS/DISC buttons to adjust the detector's sensitivity. Higher sensitivity increases detection depth but may also increase false signals.
• The ATX offers adjustable discrimination to help ignore unwanted targets. Refer to the LED display for discrimination levels.

4.6 Pinpointing

To pinpoint a target, switch to Non-Motion mode or use the RETUNE/PINPOINT button. Move the coil slowly over the target area until the strongest signal is heard, indicating the target's center.

5. Maintenance

Proper care will extend the life and performance of your Garrett ATX.

5.1 Cleaning

• After each use, wipe down the detector with a damp cloth to remove dirt, dust, and salt residue.
• Do not use abrasive cleaners or solvents.
• Ensure all connections are clean and free of debris.
• The search coil can be rinsed with fresh water.

5.2 Storage

• Store the detector in a cool, dry place, away from direct sunlight and extreme temperatures.
• If storing for an extended period, remove the batteries to prevent leakage.
• Use the provided soft storage/travel case for protection during transport and storage.

5.3 Battery Care

• Always use the correct type of batteries (AA alkaline or rechargeable).
• Charge rechargeable batteries fully before use and periodically during long storage.
• Avoid overcharging or completely draining rechargeable batteries.

6. Troubleshooting

Refer to this section for common issues and their solutions.

6.1 No Power

• Check if batteries are correctly installed with proper polarity.
• Ensure batteries are fully charged or replace with fresh alkaline batteries.
• Verify the battery compartment is securely closed.

6.2 Erratic Signals or False Alarms

• Perform a ground balance procedure.
• Reduce sensitivity settings.
• Check for electromagnetic interference from power lines, cell phones, or other electronic devices.
• Ensure the coil cable is tightly wrapped around the stem and securely connected.

6.3 Poor Detection Depth

• Increase sensitivity settings, if ground conditions allow.
• Ensure the coil is parallel to the ground during sweeps.
• Re-ground balance the detector.
• Check battery levels; low batteries can affect performance.

6.4 Headphone Audio Issues

• Ensure headphones are securely plugged into the correct port.
• Check headphone cable for damage.
• Adjust the volume setting on the detector.
