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 jewelry, 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 Discrim number, etc.

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

AT MAX’s other features include:

Iron Audio™

Hear discriminated iron (normally silenced) to avoid digging tricky, undesired flat iron items.

All Metal Iron Audio™

Garrett Exclusive 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. Weatherproof design also protects against dusty and humid environments. 
For underwater use, optional wired headphones must be used.

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.

Fast Recovery Speed

Notch Discrimination

Coin Depth Indicator

Battery Condition Indicator
