 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.

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.

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

AT MAX’s other features include:

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

  1. AT Max on the beach 4 Star Review

    Posted by on 30th Jan 2018

    I tried my AT Max on a beach in Tasmania at low tide so had dry sand and lots of wet sand at the waters edge. I tried it out in coins mode with the sensitivity about half way. All I did was to ground balance it as per the instructions, once on the dry sand, then again when I shifted to the wet sand. It seemed to be fairly quiet with only the occasional chirrp or squeak, and when I threw down a dollar coin, it definitely beeped with a really clear tone. That was when I held the coil about 100mm off the sand. I have read some disparaging comments about its performance on the beach, but so far, without even fine tuning things, I found it to run nice and stable, and to easily identify a modern dollar. I even managed to put it up to max sensitivity and it ran comfortably stably. It seems to have heaps of potential and lots of useful adjustments. I am very pleased with my AT Max and am looking forward to checking out more beaches as well as parks

  2. So Far So Good 5 Star Review

    Posted by on 9th Nov 2017

    Well I have had the AT Max for a few weeks now and I am pleased with the results. I have been over old ground I thought I had done to death and on both occasions found silver I had missed with my AT Pro and my Minelab ETrac.
    I love the back light display (about time) but I hate the screechy sound, like the AT Gold. Easy to use though and adjust . If it keeps finding silver I'll put up with the screechy tones.

  3. Great all-purpose detector 5 Star Review

    Posted by on 6th Nov 2017

    I love this detector. Super easy to use and great sensitivity and depth on all targets. The wireless audio pairs instantly and is painless to use. Really like the snappy PWM audio too. My only gripe is the tone segments. Garrett should have kept the U.S. tones for the international version, as the mid band is too narrow and causes a loss of tonal granularity between medium and high conductivity targets. Not a big deal though as you can still read the target ID which works very well. Overall very happy and highly recommended.
