  • One of the major pros of Garrett AT Max is its classic construction that has been proven the most handy, has been used for decades by different manufacturers and seekers, and seems to never go out of fashion.
  • Another pros is that all details of the construction are tightly connected. One has to take an effort to dismantle the metal detector, and it may piss off at times, but this approach protects the inside from water and dust.
  • One of the cons is the weight of the device which comprises 3 lbs. Considering that there are lighter models available, this is a con, but experienced seekers claim that with such level of quality, additional 300g are not a game changer. Due to convenient and user-friendly handle, you are unlikely to change arms every hour, or grow tired in an hour or two.

Garrett AT Max Key Features

VLF Technology

Produces an electromagnetic field that impacts the location in a continuous sinusoidal wave.

DD Coil

The most optimal and universal shape of the search coil, fitting well for mineralized soils or water bodies.

Manual Ground Balance

Optimal combination that gives the user a wide range of maneuver to cope with mineralized soils or waters.

Wireless Headphones

Compatibility with wireless headset allows freer movement on complicated locations.


Up to 10 feet is quite enough for usual diving on the beach.

Frequency Shift

Metal detector shifts the frequency in order to avoid noise and chatter due to electromagnetic interference.

Garrett AT Max Overview

Compared to all other models of metal detectors by Garrett, AT Max offers the lowest searching frequency of 13,6 khz. This frequency is considered one of the most one-size-fits-all for metal detecting. Due to that, this model of the detector allows to search for big and small objects alike; it performs better during the beach search, allowing to set higher sensitivity and gives less false signals on mineralized soils.

While it seems that having several frequencies on one metal detector is a brilliant idea, in reality, it’s not, because no one is going to check the same section with several frequencies, one by one. Therefore, having one best frequency is an optimal decision.

This feature, together with enhanced software and classic construction, makes AT Max a new hit among all the products by Garrett. Below, we’ll talk about new features and the main pros and cons in more detail.

What’s New

There is a bunch of new stuff added to this model. Here are the functions you can now enjoy when metal detecting:

All these new features, however, do not overcomplicate the setting and functionality. In fact, this model is among the simplest in settings and usage, because it offers only the most demanded options and does not make the user to make unnecessary choices. This is a simple, high quality, and reliable device.

Search Modes

All Metal

In this mode, the detectorist gets the maximum sensitivity to all types of item, plus the maximum depth possible, taking the soil type into consideration. True All Metal is a handy multifunctional mode.


A customizable combination of settings can be saved in this mode, in contrast to preset modes. The user can change this mode according to their needs and conditions.


Classic search mode for coins, since coins are among the most popular and the most frequently found items in hobby metal detecting.

Zero Discrimination

The name speaks for itself, Zero Discrimination means no metal type is filtered out, and the user has a chance to overview what is out there. Sometimes this approach brings interesting results.


Generally, one may find that in terms of construction the AT Max model has little difference from the AT Pro; the only noticeable difference and improvement is handle made of high quality rubber, instead of the previous useless and uncomfortable foam handle. The developers claim that due to this new handle, the metal detector is more balanced now, so the user will not feel tired too fast. However, the new software features it offers makes user experience even better. In addition, there are other features available:

So, obviously, the Garrett company does a good job in releasing new models that it really enhances, and at the same time keeping all the good things its older models are loved for.

The Kit

The kit includes:

It is not clear yet whether the company will continue to offer gifts within the kit as soon as the model gains its popularity, but for now, this kit seems to be a real deal.


Garrett AT Max is a professional, reliable metal detector, comparatively lightweight, easy to set and use. Its classic construction together with improved rubber handle makes metal detecting less physically exhausting. It may be a bit more expensive than other models, but its features and the level of functionality promise better user experience from the very first minute of turning it on. Simple settings, protection from moist, quality signal, wireless headphones, and a bunch of other cool benefits will make each of your searches more productive than you expect.
