Technical Specifications
In-Depth Field Performance
Detection Depth & Coverage
In field testing, the Garrett ACE 300 demonstrates consistent target acquisition across various soil types. The 7" x 10" PROformance DD provides excellent ground coverage while maintaining sensitivity to smaller targets. With a maximum detection depth of 6-8" (coin), 10"+ (larger), it performs admirably for beginners and coins hunting. Recovery speed between targets is adequate for most hunting conditions, making it suitable for recreational hunting.
Target ID & Discrimination
Target identification on the Garrett ACE 300 uses 8 segments to differentiate between valuable finds and junk. The 5 search modes provide flexibility for different hunting scenarios. Audio feedback is clear and responsive, helping you make quick dig decisions. The Speaker + headphone jack delivers clear tones even in noisy outdoor environments.
Technology & Ground Handling
Garrett equipped the Garrett ACE 300 with 8 kHz technology, ideal for coins, jewelry, and common relics. The Preset system automatically adapts to changing ground conditions. The submersible coil allows hunting in wet grass, shallow streams, and rainy conditions.
Build Quality & Ergonomics
Weighing 2.8 lbs (1.27 kg), the Garrett ACE 300 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. 20-25 hours means less worry about power during full-day hunts.
Settings & Modes Guide
Choosing a Search Mode
The Garrett ACE 300 offers 5 search modes. For coin hunting in parks and yards or light relic hunting, 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 ACE 300 runs on 8 segments. Notch narrowly rather than rejecting broad ranges of the scale — wide notches on a segmented display bury real targets that share a tone with trash.
Ground Balance
The Garrett ACE 300 uses Preset ground balance, so it compensates for mineralization on its own. You don't need to manually ground balance before each hunt, though depth in extremely mineralized or black-sand soil will be more conservative than on a detector with a manual override.
Sensitivity & Mineralization
The Garrett ACE 300 runs at 8 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
- Excellent beginner-friendly detector
- Digital Target ID for accurate identification
- Lightweight and easy to use
- Great battery life (20-25 hours)
- Made in USA quality
- No adjustable frequency like ACE 400
- Preset ground balance only
- Smaller coil than ACE 400
First-time metal detectorists who want a reliable, easy-to-use machine without overwhelming features. Perfect for learning the hobby with room to grow.
Advanced users who need multi-frequency or specialized features. Also not suitable for highly mineralized gold country without ground balance.
Things to Know Before You Buy
No adjustable frequency like ACE 400
This affects which target types come in easiest — check it against what you actually hunt.
Preset ground balance only
Something worth weighing before you buy, based on real owner feedback.
Smaller coil than ACE 400
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 ACE 300
A detector on its own finds targets it cannot recover. These are the tools experienced detectorists carry on every hunt — about $184.88 for the set, and none of them are optional once you have dug a few holes.

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.

The faint targets are the deep ones. A speaker loses them to wind and traffic long before the coil does.
Check PriceFrequently Asked Questions
In optimal low-mineralized soil, the Garrett ACE 300 can detect a quarter-sized coin at 6-8" (coin), 10"+ (larger). 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.
Yes, the Garrett ACE 300 is excellent for beginners. It offers intuitive controls, preset search modes, and reliable target identification. The learning curve is manageable, and most new users are finding targets within their first hour of use.
The Garrett ACE 300 is coil-only waterproof (Coil only): the searchcoil and lower shaft can be submerged, but the control box must stay dry. This is not a diving or full-submersion detector — but it is perfectly fine for wet sand, shallow streams, light rain, and dew-covered grass. If you plan to wade in water above the shaft or work the surf zone, you'll want a fully waterproof model instead.
Start on the search mode closest to "coins" — the Garrett ACE 300 ships with 5 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 let the automatic ground balance handle mineralization for you. Tighten discrimination and sensitivity once you know what the local trash sounds like.
The Garrett ACE 300 uses 8 segments 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.
The standard Garrett ACE 300 package includes: the detector unit, 7" x 10" PROformance DD, coil cover, headphones, requires AA batteries (sometimes included), and user manual. Some retailers offer accessory bundles with additional coils, carrying bags, and digging tools.
Yes, Garrett provides a 2 years manufacturer warranty for the Garrett ACE 300 in the USA through authorized dealers. As a USA-made product, service and parts are readily available. Register your detector after purchase for full warranty coverage.
The Garrett ACE 300 at $269.99 competes with entry-level detectors from Minelab and Nokta.
