2. Safety Information
Always exercise caution when metal detecting. Before digging, ensure you have permission to search the area and are aware of any underground utilities or hazards. Wear appropriate protective gear, such as gloves and sturdy footwear. Avoid detecting in areas with live electrical lines or unexploded ordnance.
3. Setup
3.1 Assembly
- Attach the search coil to the lower stem using the provided bolt and wing nut. Ensure it is securely fastened but not overtightened.
- Insert the lower stem into the middle stem, adjusting the length to a comfortable position. Secure with the camlock.
- Slide the upper stem (with the control housing and arm cuff) onto the middle stem. Adjust the length and arm cuff position for ergonomic use. Secure with the camlock.
- Wrap the search coil cable snugly around the stem, leaving enough slack near the coil for movement, and plug the connector into the control housing. Ensure the connection is tight to maintain waterproof integrity.
3.2 Battery Installation
The AT Max requires 4 AA batteries (included). Ensure the battery compartment is clean and dry before inserting batteries. Observe correct polarity (+/-) as indicated inside the compartment. Securely close the battery compartment cover to maintain the waterproof seal.
3.3 Headphone Connection
The Garrett AT Max features Z-Lynk Wireless Technology for near-zero delay audio with the included MS-3 wireless headphones. To connect, ensure both the detector and headphones are powered on and within range. Refer to the MS-3 headphone manual for specific pairing instructions if needed.
