Garrett AT Max Features and Advantages

The Garrett AT MAX is a good treasure hunting detector. It has some features that are good for finding treasure. Here are some of the things it can do:

The Garrett AT Max metal detector offers maximum detection with powerful, wireless, all terrain performance. Enhanced electronics, a 13.6 kHz operating frequency, and eight Sensitivity/Depth adjustments allow you to detect targets deeper than other Garrett AT detectors. The Garrett exclusive Automated Ground Balance Window feature can simultaneously "spread" the ground balance setting to a range of values to reduce ground response in severely mineralized areas. Automatic and manually adjustable ground balance options also available.

Superfast Z-Lynk wireless technology is SIX times faster than Bluetooth. Integrated circuitry transmits audio to your wireless headphones. Auto pairing. No cables, and no interference from other wireless devices. Hunt Day or Night with the backlit display feature that allows you to continue hunting in low light conditions. The Iron Audio feature allows you to hear iron trash before you dig it! Also includes True All Metal Mode, All Metal Iron Mode, Digital Target ID and Adjustable Threshold to better hear targets.

Sync your Pro-Pointer AT to your Z-Lynk enabled detector to hear both detector and pinpointer alarms in your headphones, even in noisy environments (beach, high winds, congested urban areas, organized hunts). The Garrett AT Max / Pro-Pointer AT Z-Lynk Special includes: AT Max Metal Detector (PN 1142060) Garrett MS-3 Z-Lynk Wireless Headphones 8.5" x11" DD PROformance Coil 8.5" x11" DD Coil Cover (installed on coil) Special Promotion Bundle Item: Pro-Pointer AT Z-Lynk wireless pinpointer (PN 1142200).

1. Z-Lynk™ Wireless Technology

When the metal detector is over a treasure, you can hear it. You can’t always hear it before you are over the treasure because there might be a delay. But with Z-Lynk™ technology, you can hear it right when you are over the target.

The technology features 17 milliseconds (near-zero delay transmission) from your detector to the headphones. That is up to four times faster than other wireless headphones and six times faster than the speed of Bluetooth.

With this improvement in signal detection, you are more likely to find your buried gem because there is no delay in the signal transmission.

To pair new headphones with the detector, you need to ensure the headphones are near the detector. Ascertain that they are turned on and simultaneously push the Iron Audio and Frequency buttons. You should see a Z-Lynk icon in the middle of your screen. If it is blinking, it means that it cannot find your headphones, and if it looks like a headphone, they have been paired successfully.

Hold the Iron Audio and Frequency buttons simultaneously if you need to cancel your headphones.

The wireless headphones do not work underwater, but the AT MAX does. To find treasures buried underwater, you need to use wired headphones.

2. Modes of the AT MAX

The left side of the screen has modes. You can pick one to use. For example, you can use All Metal mode, Coins mode, and Zero mode.

When you hunt with the All-Metal mode on your metal detector, it can detect all sorts of metals, even if they are small and not much metal is around. I’ll discuss this in further depth later in this review.

Custom mode allows you to save your favorite pattern of discriminating. That means, if you are looking for anything other than coins, for instance, you can set up your detector with this setting. And it will remember the setting, saving you time in the future.

The Coins mode is easy. It detects all coins, so you are more likely to miss trash or unwanted items that are not coins. The disadvantage of this strategy is that you can lose out on modest jewelry pieces while most gamers are looking for cash and other items.

The Zero mode is when you don’t have any specifics in what you are looking for. For example, if you want to find anything buried, this is the right option. The detector will give different beeps for different metals with the Zero mode. That way, it will be easier to figure out what’s buried under the soil.

3. Audio Tones

There are three tones the AT MAX uses to tell you what is a treasure or not. You can use it to find treasures from coins, custom, or zero.

The tone you will hear in your headphones will be below for items with a digital target ID rating of 0 to 34. An example is an iron nail with a digital target ID rating of 0-34. The next high-pitched tone you hear is slightly louder for an item with a digital target ID rating of 35-75, like a gold ring. The loudest high pitch tone you can hear in your headphones signifies an item with a digital target ID rating higher than 75. This would be something like a US dollar coin or quarter.

When you hunt with the All Metal mode, you will hear the middle tone no matter what is buried under the ground. But using the All Metal Iron Audio feature also lets you hear more precise sounds.

4. Operating Frequency

The AT MAX metal detector has the lowest operating frequency of any in the Garrett AT series. This means it should have more depth than other ATs, but it does not distinguish targets. However, there are no other metal detectors with an operating frequency of 13.6 kHz on the market. One could argue that the best characteristic of this model is its ability to perform effectively in both detection and separation. However, the AT MAX is not a multi-frequency metal detector. You can adjust the frequency to make it less likely to be interfered with by other detectors, but you cannot change it on a large scale.

5. Manual and Automatic Ground Balance

A professional-standard detector has a feature called ground balance. It helps cut out interference and chatter while making the detector work better when hunting in different areas with different soil conductivity or mineralization, or even when near saltwater.

The AT MAX has a machine that makes the ground stand more even. You only need to hold the SHIFT button for it to work. The device can’t balance on very rugged terrain. That is why there is an option for manual settings.

Now, in saltwater terrains, the AT MAX metal detector does better than other detectors. But you may have to make a compromise when it comes to how deep you can find things.

I have highlighted the features in this Garrett AT metal detector that are different from other models in their line. It has a special sound alert to tell you if you found treasure.

6. Iron Audio

To avoid unwanted items like flat irons while digging, the AT MAX has a sound that only sounds when it finds iron. And it has a sound that can change the frequency of metal to ensure there is no interference.

7. Digital Target ID

The digital Target ID is in all Garrett detectors. The AT MAX detector has a quicker and more accurate ID than other detectors. But note that this feature works better when the ground balance is set correctly for the environment.

8. Adjustable Audio Threshold

Some treasures are hard to find. You can set the audio threshold on them so that you can hear faint targets.

9. Fast Speed

Z-Lynk™ Wireless Technology is a new technology that transmits audio through wireless headphones. It automatically pairs with other devices and is faster than Bluetooth. This means that you are more likely to have heard the sound before it moves, with almost no lag time.

10. Pulse Width Modulation Audio

If you use this, you can listen to the sound of the target and decide if it is worth digging. You get more information about the target (audio-wise). Digital IDs are not as good as audio IDs because they do not give out all information.

Tips for Buying an AT Max Detector

Garrett’s AT Max is an extremely handy tool. It can be used for both recovering lost items and digging up history. This makes it a unique tool that provides an interesting experience.

The ideal purchaser of an AT Max is someone who is familiar with metal detecting and is searching for strong equipment capable of locating stuff deep underground.

If you are new to metal detecting, starting with a less complex machine would be good. You might want to consider the Garrett ACE series, including the ACE 200, ACE 300, ACE 400, and the ACE Apex.

Some people looking for the Garrett AT Max might want to be aware of some problems with the machine. First, there is the issue of Garrett AT Max chatter.

Chatter is a noise that is sometimes caused by electrical signals. This can be due to many things, like ground mineralization or high sensitivity. While this does not necessarily indicate an issue with the detector, it may annoy some users.

You can reduce the chatter you hear by turning down the sensitivity. The AT Max may be harder to use for beginners than other detectors. But this isn’t the fault of the machine. It’s just something to be aware of.

 Garrett AT Max Features & Benefits

The AT Max is a mid-level metal detector with various features that make it one of the most competitive detectors on the market. Continue reading for a more detailed examination of each of these qualities.


One of the best things about our AT (All-Terrain) series is that they are built to last in saltwater, rain, sleet, and snow.

This is a great feature because many detectorists want to treasure hunt in rivers, lakes, and beaches. The AT Max can be used in water up to 10 feet deep, and it also works well in saltwater environments.

This is a comfort, as many of us are clumsy and could drop the detector into the water!

The detector’s underwater nature contributes to its versatility. People who hunt for jewelry at the beach and people who hunt for Civil War relics in freshwater rivers will both love it.

The ruggedness of the device extends to its battery life. The device can last for up to 20 hours with four AA batteries.

Operating Frequency

The VLF (very low frequency) AT Max has a frequency of 13.6 kHz. This is a good frequency for a multi-purpose machine because it gives you great depth and sensitivity.

This type of operating frequency helps us find smaller targets at a greater depth. The best part is that this multi-purpose frequency is great because it is like getting three different metal detectors for one!

With 13.6 kHz, you can discover gold nuggets, jewelry, coins, antiquities, and other metal treasures.


The AT Max’s bigger display LCD screen is one of the best in the industry. It features a backlight, making it easier to see in different lighting conditions.

The backlit display enables metal detecting to continue in low-light circumstances. It lights up the LCD display and makes it easier to see what is on the screen.

Besides the backlight feature, the control box on the Max also has a detection depth indicator, a digital target ID indicator, search mode selection, a battery indicator, and sensitivity controls.

There are different buttons on a metal detector that serve different purposes. You can adjust the detector’s settings, like its sensitivity and how it searches for metals.

Wireless Technology

Metal detection can continue in low-light conditions due to the backlit display. This technology allows for wireless headphone use with metal detectors.

If you’re a metal detectorist, you know that it’s really annoying when your headphone cord gets tangled. But don’t worry, because, with Z-Lynk technology, the signals are transmitted and received six times faster than Bluetooth!

If you are metal detecting in water, consider Garrett’s Underwater Headphones, which can be submerged up to 200 feet.


One important feature of metal detectors that is often overlooked is how comfortable they are.

How a detector is designed affects how long you can use it and how fun it is. The design can also make you better at finding things with a metal detector.

The AT Max weighs about three pounds. This is a good weight for a metal detector because it is not too heavy and not too light. Most people should be able to use it comfortably all day long while looking for treasures.

The detector has a rubberized, textured grip that will help you hold onto it, even if your hands are sweaty. This will enable you to utilize the detector for an extended time.

The machine is adjustable in length, making it easy to customize for each individual. Additionally, the armrest is padded and comes with an adjustable arm strap for added comfort, a small feature we appreciate.

Ground Balancing

Mid-level metal detectors can often be overlooked. People might not think about their ground balancing capabilities.

Ground balancing is the capacity of a metal detector to detect things buried in the ground despite interference from highly mineralized soils and other unusual ground conditions.

The Garrett AT Max metal detector is good for finding things on the ground because it has a ground balance control.

The Max has three different ground balance settings: automatic, manual, and the Garrett-Exclusive Automatic Ground Balance Window.

The automated ground balance helps to eliminate any unique interference signals from the ground by spreading different high-resolution ground balance setups.

Iron Discrimination

Suppose you want to find silver or other high-conductivity metals. In that case, it is smart to crank up the notch discrimination on several levels. This will help you avoid wasting time on metals you don’t want.

The AT Max will not allow you to hear target tones, but it will still show you numbers for any metals you have discriminated against. The Max has 44 iron discrimination segments, which means you can find more of the metals you want and less of the metals you are trying to avoid.

When hunting in an area with many old nails, it is important to use some discrimination. This means that you can choose how much control you want over each type of metal. The AT Max allows you to do this to pinpoint the level of discrimination you need.

Iron Audio

Iron Audio is a Garrett-Exclusive feature that lets you hear discriminated iron if you turn the feature on. It might seem not helpful, but using all-metal Iron Audio allows you to hear the target’s complete signal. You can figure out if it’s a washer, bottle cap, or something similar.

Search Modes

People love choices, and Garrett AT Max’s metal detector has plenty of them.

The AT Max has many search modes, including True-All Metal Mode, Coin mode, Zero discrimination mode, and a custom mode. It also has an electronic pinpointing mode. This is perfect for any situation.

One of my favorite modes is the True-All Metal Mode. This mode allows all types of metal to be detected, making it easier to find things deep down.

The pinpointer function assists treasure hunters in swiftly determining the precise location of their goal.

The custom search mode lets you choose what metals your detector will pick up. You can set the discrimination settings exactly as you want, giving you more control over what your detector finds.

Each time you use the Max, it remembers your customized settings, so you can enjoy turning on the gadget and immediately starting metal detecting!

Search Coil

The Garrett AT series is known for its high-quality search coils, and the AT Max is no different.

The Max comes with a PROformance DD search coil built for performance. Many experts at Kellyco love DD search coils!

The DD search coil is beneficial because it quickly covers a large amount of ground.

DD PROformance search coils often offer a much greater detection depth than other search coils. Generally, the larger the search coil, the greater the depth it will offer to treasure hunters.

This metal detector comes with a Garrett coil cover. This will protect your search coil while you’re looking for metal.

Bottom Line

If you use your Garrett AT MAX metal detector, you should learn how it works. You can find instructions online or in a booklet that comes with it. It is not hard, and if you learn how it works, you will not regret buying this product. You can go back to old hunting sites and find new treasures there.

More than that, the metal detector is rather cheap and won’t break your bank.
