Technical Specifications
In-Depth Field Performance
Detection Depth & Coverage
In field testing, the Garrett AT Gold demonstrates consistent target acquisition across various soil types. The 5" x 8" DD PROformance provides excellent ground coverage while maintaining sensitivity to smaller targets. With a maximum detection depth of 8-10" (nugget), it performs admirably for gold and prospecting hunting. Recovery speed between targets is fast enough for trashy sites, making it suitable for competition-level detecting.
Target ID & Discrimination
Target identification on the Garrett AT Gold uses Iron Audio to differentiate between valuable finds and junk. The 3 search modes provide flexibility for different hunting scenarios. The Iron Audio feature lets you hear masked iron targets—a game-changer for relic hunters working in nail-infested sites. The Speaker + headphones included delivers clear tones even in noisy outdoor environments.
Technology & Ground Handling
Garrett equipped the Garrett AT Gold with 18 kHz technology, which is optimized for detecting a wide range of targets from gold jewelry to silver coins. The Manual + Auto system gives experienced users full control over mineralization compensation. Full waterproof capability to Full to 10 ft opens up beach and shallow water hunting opportunities.
Build Quality & Ergonomics
Weighing 2.9 lbs (1.32 kg), the Garrett AT Gold is lightweight enough for extended hunting sessions without fatigue. The 42" to 51" adjustable accommodates users of different heights. Build quality is excellent—made in the USA with quality materials. 12-15 hours means less worry about power during full-day hunts.
Settings & Modes Guide
Choosing a Search Mode
The Garrett AT Gold offers 3 search modes. For gold prospecting or gold prospecting, start with the preset closest to that target type — it pre-loads discrimination and tone breaks tuned for it — then fine-tune discrimination and sensitivity from there as you learn the site.
Discrimination Setup
Discrimination on the Garrett AT Gold runs on Iron Audio. Notch out just the low end to reject ferrous trash — nails, foil, pull tabs — and leave mid-to-high tones open so you don't bury coins and jewelry that sit near those signals. Run Iron Audio alongside discrimination rather than instead of it — it lets you hear a masked iron target under a good signal instead of silently notching the whole area out.
Ground Balance
The Garrett AT Gold's Manual + Auto ground balance gives you both options. Leave it on auto/tracking for normal parks and fields — it adjusts on the fly and needs no attention. Switch to manual in heavily mineralized soil, black sand beaches, or old homesites where auto-tracking can drift: pump the coil a few inches over clean ground until the threshold stops changing, lock it in, and re-check whenever the soil type changes.
Sensitivity & Mineralization
The Garrett AT Gold runs at 18 kHz. In average, low-mineralization soil, sensitivity can run near the maximum stable threshold for the deepest signal. In mineralized ground — red clay, black sand, or salt-contaminated soil — back sensitivity down until the false chatter settles, then re-check your ground balance.
Pros & Cons
- 18 kHz frequency excellent for small gold
- Fully waterproof for stream hunting
- True All-Metal mode for max sensitivity
- Ground Balance Window handles mineralization
- Smaller coil perfect for tight spots
- Higher price than general-purpose detectors
- Less ideal for coins (high frequency)
- Smaller coil covers less ground
Gold prospectors hunting nuggets in mineralized ground. High frequency and ground balance capabilities are essential for this application.
Those who plan to hunt exclusively in saltwater or need maximum depth. Consider upgrading to a waterproof model with manual ground balance.
Things to Know Before You Buy
Higher price than general-purpose detectors
Weigh this against how often you'll actually use the extra capability — it's real money either way.
Less ideal for coins (high frequency)
This affects which target types come in easiest — check it against what you actually hunt.
Smaller coil covers less ground
A smaller coil trades ground coverage for maneuverability in tight spots — an aftermarket coil can offset this if it matters for your sites.

What Else You Need With the Garrett AT Gold
A detector on its own finds targets it cannot recover. These are the tools experienced detectorists carry on every hunt — about $220.87 for the set, and none of them are optional once you have dug a few holes.
Garrett Pro-Pointer AT
The coil gets you inside a foot. A pinpointer gets you to the exact inch, which is the difference between a two-minute recovery and a ten-minute hole.

Garrett Edge Digger
You cannot recover a target without digging it. A serrated digger is the first thing every detectorist buys after the machine itself.

GADFISH Stainless Sand Scoop
On sand, a digger is useless — the hole collapses before you reach the target. A sifting scoop is the only practical recovery tool at the beach.

The faint targets are the deep ones. A speaker loses them to wind and traffic long before the coil does.

In optimal low-mineralized soil, the Garrett AT Gold can detect a quarter-sized coin at 8-10" (nugget). Larger objects like relics and caches can be detected at greater depths. In highly mineralized ground, expect 15-20% reduction in depth. Actual results depend on soil conditions, target size, and discrimination settings.
The Garrett AT Gold is designed for experienced detectorists who want more control and features. Beginners can use it but may need time to learn the advanced settings. Consider the Garrett entry-level models if you're just starting out.
Yes — the Garrett AT Gold is fully waterproof (Full to 10 ft), making it excellent for beach and even shallow-water hunting. You can hunt the wet sand, surf zone, and shallow water without worrying about the control box. The 18 kHz handles saltwater mineralization well.
Start on the search mode closest to "gold" — the Garrett AT Gold ships with 3 search modes, and the closest match pre-loads discrimination and tone breaks for that target type. Keep discrimination low at first so you don't skip real targets while you learn the site, and ground balance manually before you start swinging. Tighten discrimination and sensitivity once you know what the local trash sounds like.
The Garrett AT Gold uses Iron Audio for target ID. Start with little to no discrimination so you learn what iron, foil, and pull tabs sound like in your specific soil, then notch out only the confirmed junk tones — narrow notches beat wide ones, since wide rejection zones also bury real targets. Running Iron Audio alongside discrimination lets you hear masked iron instead of silently skipping over it.
The standard Garrett AT Gold package includes: the detector unit, 5" x 8" DD PROformance, coil cover, headphones, requires AA batteries (sometimes included), and user manual. Some retailers offer accessory bundles with additional coils, carrying bags, and digging tools.
