Garrett AT Pro Underwater Metal Detector Review: Pros, Cons, and Best Use Cases

What the Garrett AT Pro is trying to do

The AT Pro is built around two ideas that matter in the field: shallow-water capability and proportional audio. Garrett rates it to 10 feet, which is enough for wading, creek edges, and other shallow-water hunts, but not a substitute for deep-diving gear. The audio style is what separates it from basic beep-and-dig detectors. Stronger targets come through with more presence, which can help on older sites that have already been searched hard.

The main reasons people buy it

The AT Pro earns attention because it covers more ground than a dry-land starter model. That matters if your hunts move between parks, permissions, wet edges, and shallow water. A detector like this is not about making one narrow type of hunt easier. It is about keeping one setup useful across several kinds of ground.

Proportional audio is the other big reason. Instead of flattening every signal into the same response, it gives you more audio detail to work with. That can help when a site is littered with junk or has already been searched a lot. You are listening for differences, not just waiting for a simple high tone.

The upside is real. The cost is also real. A detector that gives you more information asks you to pay attention to what the machine is saying. If you want the shortest path from box to first target, this is not the easiest way to get there.

Pros that matter in day-to-day use

• One detector for more than one environment. The AT Pro is useful when your hunting changes from dry ground to wet ground and shallow water. That keeps you from needing a separate water-only setup just to cover the basics.
• Audio detail that can help on worked-over sites. Proportional audio is the feature most likely to matter once you move beyond easy ground. It gives you more nuance to listen for in trashy places and old sites that have already been dug over.
• A practical water rating for real-world hunts. A 10-foot rating is enough for shallow-water use, creek edges, and wet recovery work. That is the kind of water use most hobby hunters actually mean when they say they want an underwater detector.
• A clearer reason to keep using it over time. Some detectors only make sense in one setting. The AT Pro has a wider job description, so it can stay useful even when your hunting spots change.

Cons you should not ignore

• It asks for more attention. Proportional audio is useful, but it is not as effortless as a simple beginner machine. You have to listen and interpret instead of just swinging and hoping.
• Wet-use ownership takes more care. A waterproof detector needs routine attention after wet hunts. Rinse it, dry it, and store it properly so the extra capability does not become extra hassle.
• Not the easiest choice for dry parks only. If your hunting never leaves dry ground, the AT Pro gives you capability you may never use. In that situation, a simpler land-first model is easier to live with.
• Bundle names can change the real value. Some AT Pro packages include Garrett MS-2 headphones and some do not. That matters because the AT Pro is more rewarding when you can hear the audio clearly.

Best use cases for the Garrett AT Pro

Older parks and permission sites

This is one of the strongest reasons to buy the AT Pro. Sites that have been hunted for years often reward detectors with better audio detail. The AT Pro is built for that kind of listening. It is less about brute force and more about hearing target differences that a simpler detector may blur together.

Wet ground, creek edges, and shallow water

If you regularly hunt around water, the AT Pro has a job to do that dry-land detectors cannot match. Wading, shoreline work, and shallow recovery all fit within its intended use. That makes it a good pick for people who do not want a separate machine for every environment.

Hunters who want one platform for varied terrain

Some people move between dry fields, damp grass, and water edges in the same week. For that kind of use, the AT Pro stays relevant instead of sitting out half the season. It is a practical choice when you want one detector to keep up with changing ground.

Buyers who are willing to learn audio

The AT Pro makes more sense when the operator is willing to listen carefully. If you want a machine that gives you a richer signal picture, this is the kind of detector that rewards that attention. If you want the most straightforward learning curve, it will feel more demanding.

Who should skip it

Skip the AT Pro if your hunting stays in dry parks and you do not need water use at all. The waterproof design will not hurt you, but it will not add much value either.

Skip it if you want the easiest possible beginner experience. A simpler land-first detector will be easier to understand, easier to store, and easier to maintain.

Skip it if you do not want to think about bundle contents. The package matters more here than it does on a very basic detector, especially when headphones are part of how you make the audio useful.

Bundle details and ownership notes that matter

The AT Pro often shows up with different bundle names, and those names are worth reading carefully. If a listing uses the International Version label, treat that as a package label, not a reason to assume you are getting a different class of detector. The machine still needs to fit your hunting style, and the bundle still needs to include the items you actually want.

Headphones are a good example. Some AT Pro bundles include Garrett MS-2 headphones, and some do not. That matters because this detector is more rewarding when the audio is clear and easy to hear. A bundle that saves you a separate headphone purchase can make the package feel more complete.

If you are buying used, look at the practical wear points: battery compartment, cable, coil area, and the general condition of the housing. Waterproof gear is only as convenient as the care it gets after each hunt. A quick rinse and dry routine is part of the deal.

How it compares with a simpler Garrett option

A Garrett ACE 300 is the cleaner comparison point if you are deciding between a mixed-terrain detector and a land-first machine. The ACE 300 is easier to live with when your hunts are mostly dry. The AT Pro is more appealing when water use and audio detail change the kind of hunt you do.

That comparison is the heart of the decision. If your hunting never leaves dry ground, the simpler model is the better fit. If water use is part of the plan, the AT Pro starts to make much more sense.

Practical buying advice

Buy the AT Pro if:

• you hunt wet ground, creek edges, or shallow water;
• you want one detector that can handle several kinds of terrain;
• you are comfortable learning audio instead of relying on a simple beep;
• you value a detector that can stay useful as your hunting spots change.

Skip it if:

• you want the simplest possible detector for dry parks;
• you do not plan to use the waterproof side of the design;
• you want the lightest maintenance routine possible;
• you prefer a machine that feels straightforward right away.

Verdict

The Garrett AT Pro underwater metal detector is a good buy for hunters who actually use wet ground, shallow water, and older sites where audio detail matters. It is not the easiest detector to learn, but that is part of why it stays interesting. You get one machine that can cover more than one type of hunt, and that is the real value here.

If your hunting is mostly dry and simple, a land-first detector will feel easier and more relaxed to own. If your sites change often and water is part of the picture, the AT Pro is the stronger choice.
