The Garrett AT MAX International is Garrett’s most versatile and advanced all-terrain VLF metal detector. With increased detection depth, built-in Z-Lynk Wireless Technology, and many other improvements, AT MAX helps treasure hunters push their limits to the MAX!

Key Features

Built-in Z-Lynk™ Wireless Technology

Cut the cord! Integrated circuitry transmits audio to your wireless headphones. Six times faster than Bluetooth speed! Auto pairing. No cables, and no interference from other wireless devices.

NEW Garrett MS-3™ Z-Lynk Wireless Headphones included

The speed of Z-Lynk Wireless Technology, and high-fidelity audio…with no cords attached!

Maximum Detection Depth

Increased transmit power and enhanced electronics provides AT Max with significant depth increase.

True All Metal Mode

Detects all types of metal and provides the greatest possible detection depth and sensitivity.

Backlight: Illuminates LCD screen for improved visibility in low-light situations.

Optimized Frequency

The AT Max’s 13.6 kHz operating frequency provides excellent detection on a wide range of targets—including silver coins, gold jewellery, and brass relics.

High Resolution Ground Balance

Automatic and manually adjustable for improved performance. Includes 175 points of Ground Balance resolution, allowing the AT Max to handle both conductive soils (such as saltwater beaches) and highly mineralized ground.

Automatic Ground Balance Window™

Garrett Exclusive feature will simultaneously ground balance to a range of values to help overcome localized ground variations. By reducing subtle ground responses, the Automatic Ground Balance Window smooths detector audio and allows the user to hear faint targets.

Larger Display Numbers: Digital Target ID number, Iron Discrimination number, etc.

More Controls: All easily accessible with a single finger as you search.
