Despite its higher price value of around $600-700, the AT Pro model delivers unsurpassed performance to those individuals who want to dig only for a specific range of targets, whether we’re talking about gold nuggets, antique coins or other collectibles.

Simply put, this metal detector is undoubtedly an excellent option if you want more control over your machine, enabling you to adjust its settings as desired to increase the likeliness of finding your next treasure.


A Complex, yet Efficient Machine for All Pro Detectorists

Garrett AT Pro Metal Detector

Powered by four AA batteries, the Garrett AT Pro is a complex machine due to the many features it is equipped with, having an efficient performance in most situations, whether we are coin shooting or relic hunting.

As for the operation, this metal detector integrates 40 levels of iron discrimination. This will enable you to successfully set the machine precisely to separate good targets from trashy ones, therefore making your experience significantly more lucrative.

Much to your delight, the AT Pro’s target ID scale is extremely wide, ranging from 0 to 99, so you can always distinguish different targets’ conductivity for easier identification while you are detecting the soil. This is a huge improvement compared to the Garrett Ace 250’s 12 segments of target ID, which were rather inconvenient and unsatisfactory for more experienced individuals.

Once you start using your Garrett AT Pro, you will certainly be pleased to see that this metal detector integrates a ground balance feature, which can be adjusted both automatically and manually to improve your machine’s operation. This is particularly advantageous if you are planning to detect mineral-rich soils, like beaches, which can interfere with your detector’s search patterns. This often results in frequent audio sounds that will only lead you to dig up for gold or other good targets, only to find nothing but sulfur chunks and the likes.

The machine also features a continuous coin depth indicator that will tell you how deep you need to dig the soil to find your target, iron audio tones for easier audio identification of the targets, as well as a convenient all-terrain design that is also waterproof, allowing you to detect underwater as well.

Things to Watch For

Although not many, there are a couple of drawbacks of the Garrett AT Pro you should be aware of. In the first place, a few customers reported that the battery life of this machine is quite poor, and will last only 25-30 hours though Garrett claims they can last up to 40+ hours.

This can give you a hard time if you plan to go metal detecting regularly, as you will need to pay for AA batteries every time your machine stops working, which can result in substantial money waste over a short period of time.

Another aspect you might find rather disappointing is the accuracy of the ground balance feature, which is not as efficient as you might expect it to be, still delivering false signals whenever soil minerals interfere with the machine’s electromagnetic field.


To wrap up the above, the Garrett AT Pro is undoubtedly a reliable metal detector for both intermediary and more advanced detectorists who want to improve their experience and find more valuable targets. Even with the above-mentioned negatives, the AT Pro is still a high-performing machine that can handle most situations very well, coming with many features and settings that make it versatile and efficient. Although you will be paying $699.95, you can be at peace knowing that your metal detector is going to meet your expectations and make your experience much more lucrative and enjoyable at the same time.

What Consumers Are Saying

According to most customers who have bought the Garrett AT Pro metal detector, this machine is extremely efficient at identifying a wide array of targets in a short time, especially due to its advanced target ID and ground balance features. One customer said he managed to dig up several items during his outings, including a couple of diamond rings, a 50-cent Euro, a 10-cent Ruble and a 28-inch silver chain from Italy.

Another buyer was very pleased with how discriminatory this metal detector is, appreciating its comfortable arm rest and waterproof housing, which was ideal for underwater detections. Apparently, the only negative point of the AT Pro from Garrett is the fact that the audio tones are difficult to hear without headphones, which will require you to spend another $99.95 on Garrett’s submersible headphones.
