It is waterproof , fully submersible and waterproof to 3 meters and can be used in both fresh and sea water.

Garrett AT Max Main 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.

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.

Garrett AT Max Metal Detector Also Features:

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.

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.
