Garrett AT MAX International Metal Detector

The new Garret AT MAX is our 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:

New 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.


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

High Resolution Ground Balance:

  • Automatic and manually adjustable for improved performance. Includes 175 ponits 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 exlusive 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 Discrim number, etc.

More Controls:

  • All easily accessible with a single finger as you search.

AT MAX’s other features include:

Iron Audio:

All Metal Iron Audio:

  • Garrett exlusive feature that audibly identifies discriminated iron while operating in a True All-Metal Mode.

Adjustable Frequency:

  • Small frequency shifts to eliminate interference.

All Terrain Versatility:

  • Fully submersible to 10-foot (3 meter) depth. Waterproof design also protects against dusty and humid environments.
  • For underwater use, optional wired headphones must be used.

Digital Target ID:

  • 0 to 99 scale.

High-Res Iron Discrimination:

  • 44 points of iron resolution

Adjustable Threshold:

  • User can manually adjust the audio threshold (the constant background sound or “hum”) to better hear faint targets.

Pulse Width Modulation Audio:

  • Proportional PWM audio response and Tone Roll Audio provide more target information and sharp, responsive target signals.

Four Search Modes:

  • True All-Metal, Custom, Coins, and Zero Discrim Modes.
