More Information

Garrett AT Max with Z-Lynk Metal Detector

Looking to find coins, rings, relics and jewelry in all environments? Look no further! One of the biggest features of the AT MAX is that it’s waterproof. The "AT" in "AT MAX" stands for All Terrain Performance and the entire detector is waterproof up to 10 feet or 3 meters. The AT Max’s adjustable ground balance feature will also help you search in mineralized soil conditions – even saltwater beaches. With automatic and manual ground balancing you can easily adjust the ground balancing in quarter point increments.Rain or shine, muddy environments and even the ocean can’t stop this machine.

Tired of digging up bottle caps? The high-resolution iron discrimination feature on the AT Max, has up to 44 points, and will help you avoid digging junk. The AT Max’s sharper audio signals and threshold adjustment will give you sharp alerts and more information about targets than other detectors. This will help you know what and where to dig before reaching for the shovel. The adjustable threshold feature is great when you are having trouble hearing fainter targets above the operational hum of the detector.

With a bigger, new back-lit display, the AT Max will allow you better visibility of settings, digital target identification and iron discrimination numbers. The AT Max also has four search modes: all metal, custom, coins, and zero discrimination. The true all metal mode provides the best depth and sensitivity – essential for serious detectorists. It also provides you with a high level of target separation, which is essential when you are hunting a site with many alerts. You will no longer miss valuable targets because you find the nail that is next to them and then walk away from the search.

Featuring an 8.5 x 11 in. DD PROformance™ Search coil for maximum detection depth, the Garrett AT Max features an optimized frequency at 13.6 kHz which provides excellent detection on a wide range of targets - including silver coins, gold jewelry and brass relics. Upgrading from the AT Pro? No problem, all Garrett AT metal detector search coils are compatible/ interchangeable (including from the AT PRO & AT GOLD).

As one of Garrett’s most advanced and versatile metal detectors, this All-Terrain detector packs all the features that Garrett customers have been asking for: built-in Z-Lynk transmit technology, new Garrett MS-3 Z-Lynk Wireless Headphones, more depth, larger display numbers, advanced ground balance resolution and even a back light. This machine is for any detectorist that wants to use their detector in different landscapes and terrains – it can even be submerged up to ten feet in freshwater. The Garrett AT Max is a solid choice for your newest detector from beginner to advanced.

    • ★★★★★ Great all around detector

    Review by Scott on October 20, 2020

    I purchased a Garret AT Max and I was pleasantly surprised at how much better the recovery speed was over the AT Pro. I have been hitting old spots and it has been able to find a lot of coins in the same holes as trash that older machines couldn’t separate from the trash. Great machine for the money.
    • ★★★★★ Never fail

    Review by FallenCrow on October 12, 2020

    I messaged KellyCo to get a certain machine. The machine was on back order. I was in no hurry to get a machine as it was winter in Maine. I did have my eye on the AT Max. I have seen videos and read the reviews. Mine let me down. The Machine is complex enough to compete with high end models and yet simple enough to turn on and go. The price is very reasonable and with the KellyCo bonus’ it makes for a great machine and bene’s. The Max is all around universal in all weather, even at 32° F, any colder and I’d be a popsicle. Give it a try.
    • ★★★★★ It works great

    Review by Logan on August 21, 2019

    It works great in Tennessee on land and water
    • ★★★★★ Awesome product

    Review by Beth H on August 20, 2019

    I always go to Kellyco for all my metal detecting needs, wishes and wants. Great prices and great customer support. I don’t look at any other companies. Total satisfaction every time!
    • ★★★★★ Best of the AT / Ace Series.. Max is the Most!

    Review by Stumpy on August 20, 2019

    I went from an ACE 400 to the AT/Max and it is a big jump in detecting. It is a bit chatty to begin with but after you get use to the noises and the items you find it becomes natural. I have found targets 14 inches with this device. Best of the Best!
    • ★★★★★ Most Versatile Machine

    Review by Mike on August 20, 2019

    This Garrett AT Max metal detector is one of the most versatile machines that I have ever used. It is very easy to operate and I have had no problems with it. I have found a lot of very good items, from coins to jewelry with it. I would encourage anyone to buy one.
    • ★★★★★ Great product

    Review by Leroy on August 20, 2019

    Been about a year loving this detector. The wireless features are awesome. Made lots of great finds.
    • ★★★★★ Absolutely Amazing

    Review by SilverSearcherWV on March 18, 2019

    This machine has some amazing improvements on my previous machines. I love the back-light, wireless headphones, and the grip, the rubber grip, thank the lord for the rubber grip. The new grip is so much easier to clean and keep clean. plus all the electronic upgrades make this an amazing machine. I highly recommend this machine.
    • ★★★★★ I Really Like this Metal Detector

    Review by Terry on December 15, 2017

    I enjoy using the AT Max. I've been metal detecting for about five months now with the AT Max and I've done pretty good with it - two Mercury Head Dimes, an Indian Head Penny, an Indian Head Nickel, four Wheat Back Pennies and around twenty dollars in new coins. So I can honestly say that I love the AT Max being one of the first metal detectors I own now, thumbs up Garrett for a wonderful metal detector.
    • ★★★★★ Great Machine

    Review by Scot on November 10, 2017

    I just received my AT Max on November 1, 2017 and all I can say is WOW!! I was using an AT Pro which I love. I knew it was going to be hard to beat in this price range but so far the Max has. On my second day using it I found my first large cent. I have only been detecting since March 2017 and mostly park hunt. I went to an old park that’s been hit to death. The Max had no problem picking it out between trash at 9”.

    It’s a different animal than the AT Pro. It’s going to be a learning curve but I can already see that it’s worth it. The wireless headphones are amazing. I fully charged them when I opened the box and a week later they still do not need charged. I have the Z-Lynk system for my AT Pro and fell in love with it. However not having any wires is great. I’ve paced off 50 steps from my detector and didn’t lose the connection.

    The machine is hyper sensitive. If you’re moving up from a Pro or Ace series it will seem noisy and scratchy at first. Take the time to play with it and adjusting it. I usually ran my AT Pro in Pro Zero, no iron disc and full sensitivity. You do not need to run the Max that wide open. I have in cleaner ground, but where I live my machines usually ground balance between 85-89. By turning down the sensitivity 2 bars and on some occasions reducing my threshold to (-2) the Machine runs on rails. Again you will need to experiment and find what works for you.

    The backlight feature has already payed off with the time change. It’s allowed me to extend my hunts.

    We will be snowed in soon here but I’m already excited about next spring. Stevie Ray has helped me with not only the purchase of my AT Max but also my AT Pro. He’s very knowledgeable on both detectors and I highly recommend asking for him if you have questions. He’s a great guy and willing to take time to answer all of you questions.

    If you’re looking for a detector that will pump up your confidence and finds, look no further than the AT Max.
