The Garrett AT Pro is one of Garrett’s most popular mid-level metal detectors and is a tremendous upgrade from its popular entry-level detector (ACE 250).
The AT Pro is considered by many seasoned detectorists to be one of the best mid range metal detectors available on the market today.
The Garrett AT pro boasts many new powerful features and options that will have you finding more targets at greater depths and with greater accuracy.
One of the best selling features of the AT Pro metal detector is that it is completely waterproof up to 10 feet.
This is almost unheard of with detectors in this price range and greatly widens the areas and conditions in which you can metal detect.
With the overall quality and number of advanced features/options the Garrett AT Pro has compared to the its modest price it’s no wonder why this detector is incredibly popular within the metal detecting community.

Garrett AT Pro Features
The feature rich Garrett AT Pro metal detector is a great addition to even the most seasoned of metal detectorists. These features include:
– Electronic PinPointing: Allows you to pinpoint the target in the ground to within a 1-2 inch circle. This greatly cuts down the recovery time of targets which means you can find more treasure in the same amount of time.
– 6 Search Modes: The Garrett AT Pro comes with 6 total search modes. 3 in standard mode and 3 in pro mode. The standard mode is setup to work just like that of the ACE 250. You will get a low, mid and high tone when you go over an object.
The pro mode however makes use of the advanced audio option(proportional audio, tone roll audio) on this metal detector which will give you a whole lot more information about the target you have your coil over.
How does it work?
Proportional audio – will emit the same type of 3 tones however the volume will be proportional to how deep the target is. If there are multiple targets in the ground and you run over both of them instead of hearing just one beep for both targets the pro audio will actually beep and then beep again for the second target.
To better explain here are a couple of illustrations from the AT Pro User Guide:
Tone Roll Audio – This gives a varying type signal based on the type of target in the ground especially for iron based targets. For example bottle cap in standard mode will give a high tone to indicate a good target.
However, with tone roll audio it will give a low tone blip followed by a high tone then another low tone. This is an indication that the target is junk and not a good target. Below is a visual representation from the AT Pro manual:
– 40 Points of Discrimination: With 40 points of discrimination, it allows you greater control and precision over the targets you can discriminate out.
– Continuous Coin Depth Indicator: Shows you as you swipe the coil over the target how deep it is before you even dig it.
– Battery Condition Indicator: With a clear battery indicator on the screen of the detector, you’ll have no problems checking the current status of the batteries in your detector.
– DD Coil: With a DD coil you will find that the Garrett AT Pro is a whole lot better at target separation as compared to a metal detector with a concentric coil. This is because instead of a cone shape that goes into the ground you have a flat D shaped fan that is able to get in between multiple objects better. Below is an illustration that should help you out.
As you can see because the DD coil features a long but narrow detection field it is better able to squeeze in between closely situated objects giving you the ability to pick out good targets in trashy areas.
Waterproof Housing and Coil – With literally the entire metal detector being waterproof up to 10 feet, it allows you to expand your hunting areas and conditions to rain or shine, rivers, lakes, ponds etc.
99 Point Digital Target ID: With 99 points of target ID it gives you a much better idea of the type of target you are digging while still in the ground. It is essentially 99 small differences in conductivity of different objects so you for example an 85 might be an old quarter, an 86 a new quarter, 87 a small silver ring, 88 big silver ring etc. (not actual id numbers and targets)
Higher Coil Detection Frequency: The Higher frequency allows the metal detector to be more sensitive to smaller targets, gold nuggets and jewelry.
Manual/Auto Ground Balance – This is a huge plus for this detector as well. With the ability to ground balance you are able to easily transition from different types of soils or area conditions without dealing with falsing and erratic detection behavior.
Depending on the manual ground balance you can also make this detector more sensitive to low conductors (gold) or high conductors (silver).
Micro Frequency Adjust – There are 4 different frequency adjustment options on the Garrett AT Pro that will allow you to cut down on the amount of falsing and erratic detecting behavior when around electrical equipment.
How to use Garrett AT Pro Pinpointing Feature
The pinpointing feature on the Garrett AT Pro is incredibly easy to use and will help you to narrow down exactly where your target is in the ground before you dig it. This will allow smaller more discrete holes, faster target recovery, and a lot less effort.
In order to use the pinpoint feature follow the steps below:
Step1: Swing the Detector over the target take note of roughly where on the ground you hear the beep on the detector.
Step2: Keeping that specific spot in your sight place the AT Pro DD coil on the ground to the left of the target location.
Step3: Press the Pinpoint button and slowly move the detector over the suspected target right and left and then up and down. The point at which the detector sound is the loudest and the bars on the visual display are the most will indicate that the target is directly in the center of the coil.
For a visual representation of these steps you can go to Garrett’s AT Pro Manual
AT Pro Display Explained
The above picture is a brief overview of the front display of the Garrett AT Pro control box with descriptions as to each function. This picture again was taken from the AT Pro Manual
This area of the display shows you which of the 6 search modes you are currently using the detector in. It will display either STD or PRO on top with the CUSTOM, COINS and ZERO after that.
The depth indicator on the Garrett AT Pro metal detector shows you roughly how deep the target is located in the ground. I say roughly because there are times when the target may be a big chunk of iron, or the target is very small and on its edge or some other type of situation where the depth will be inaccurate. It will give you a decent indication but don’t put all of your trust into this reading.
Target ID Cursor
The target ID Cursor actually has 2 functions.
Function 1: When you have located a target this indicator will show up underneath the top display pointing to what you possibly may have found. In this case the indicator is pointing to the 82 or non ferrous type target likely silver.
Function 2: When you are using the pinpointing feature on the Garrett AT Pro, as you slowly move your coil across the suspected target location, the target number of target indicator bars will increase from left to right. When the whole top is full you will know you are directly over the target.
The Display shows a triangle with a 30 and then black squares that follow. The triangle portion shows the amount of high resolution iron discrimination being used. The little black squares show the target ranges that have been either disallowed or allowed.
If a black box is present you will hear a tone if target is found if not then the indicator will show up but no noise will be made.
The sensitivity indicator is increased or decreased by the sensitivity + or – buttons. Low sensitivity (less bars) will mean that you are picking up only bigger objects, whereas higher sensitivity will pick up much smaller targets. Depth is not directly related to sensitivity however it is affected a little by the sensitivity setting.
This area of the Garrett AT Pro shows the types of likely targets based on the different indication signals. This helps you to determine what the target may be before you dig it. While unlike the Ace 250 this legend is more vague it basically shows what types of metals are found in each number ranges.

I like this video because so many people go after the higher tones and VDI numbers however this video shows what kinds of VDI numbers come up for different types of gold jewelry. It may surprise you.
Garrett AT Pro Tips and Tricks
Swing Slow and Steady
Metal detecting is not a race, and swinging your metal detector like crazy and walking a mile a minute is not going to get you anywhere. The key to finding great targets especially the deep ones is to take your time and swing your coil at a good pace. Listen for all of the sounds the AT Pro is trying to tell you.
Ground Balance Often
The Garrett AT Pro gives you the ability to manually ground balance the detector which will come in extremely handy when you are hunting and the ground type changes or you go from dry to wet ground.
Whenever you move to a new area or you notice that your AT Pro is falsing and chattering a lot re ground balancing will usually take care of the problem and you will be ready to hunt again.
Ensure Connections Tight
The Garrett AT Pro metal detector comes with special connectors for both the coil and the headphones. These connectors if you have bigger fingers can be tough to tighten all the way.
It is very important that you ensure these connections have been screwed on tightly enough to keep water out. Using a small set of pliers to ensure the connection is tight is recommended. (Don’t over tighten, a snug fit is all you need.)
Keep the Coil Low
One of the biggest selling points of any detector is its depth ability. The deeper the detector goes the more you pay and so it is essential that you are detecting with every bit of depth you paid for.
The higher the coil is off the ground the more of that expensive depth you’re losing in the ground.
Detect in Wet Ground
The Garrett AT Pro metal detector is waterproof which is great because detecting wet ground allows you to get extra depth.
This is due to the increased conductivity that moist soil provides. Going out after a rain may just get you some deep targets the AT Pro didn’t see in the dry ground.
Go All Metal
Going all metal improves the depth at which your detector can detect those good targets. With the high resolution iron discrimination and the iron audio you can get the max depth and get a bigger overall picture of what is in the ground.
This is especially helpful in trashy areas where there are great little nuggets hiding in among the trash.
Use Rechargeable Batteries
The Garrett AT Pro metal detector requires the use of 4 AA batteries, which can begin to get quite expensive depending on how much you use your detector.
Getting a good set of rechargeable batteries is a great way to save you some decent money in the long run.
Wind Coil Cord Tight
It is important to remember to ensure that the coil Cord that connects to the AT Pro control box is wound around the shaft nice and snug.
The idea here is that you don’t want any part of the cord hanging loosely above the coil as it can cause your detector to false and give inaccurate target readings.
The Garrett AT Pro metal detector in an incredible mid-level machine with a ton of great features that will make your metal detecting hunts a lot more productive and enjoyable.
The AT Pro is not only a good solid quality machine but the price to feature ratio truly makes it the best bang for your buck. It’s no wonder why the AT Pro is one of the best selling and top recommended metal detectors within the metal detecting community.
