Garrett ACE 300 Metal Detector: The Complete Verdict
Introduction & First Impressions
If you’ve been searching for your first real metal detector — or you’re upgrading from a cheap toy unit — the Garrett ACE 300 metal detector is likely already on your list. And for good reason. This USA-made, beginner-friendly machine has quietly become one of the best-selling detectors in North America since it launched in 2016. In 2025, it still holds its own.
Bottom Line Up Front: The Garrett ACE 300 is the sweet spot between “too basic to be fun” and “too complicated to bother.” If you want to find coins, jewelry, and relics in parks, fields, or dry beaches without spending $500+, this is your machine.
I’ve been a hobby detectorist for over five years. I’ve swung everything from $80 toy units to $800 multi-frequency machines. I tested the ACE 300 for six months straight — parks in suburban Ohio, a 200-year-old homestead in rural Pennsylvania, and dry sand at the Jersey Shore. This review is based on real dirt time, not a spec sheet.
The Garrett ACE 300 kit, as it arrives — detector, waterproof coil, headphones, covers, and manual.
The first thing that hit me when I unboxed it? It feels like a real detector. The stem is solid, the coil is bigger than I expected, and the control box layout made sense within five minutes. No flimsy plastic feel, no confusing menus. I was detecting in a local park within 20 minutes of opening the box.

Design & Build Quality
Garrett built the ACE 300 in the USA at its Garland, Texas, facility. That matters. The tolerances are tight, the stem cams lock securely, and the whole unit has a confidence to it that cheap offshore detectors just don’t match.
The control box sits on top of the stem and features a clear, backlit LCD screen showing your Target ID number (0–99), depth indicator, battery level, sensitivity setting, and discrimination pattern — all at once. The six control buttons are tactile and labeled clearly. You won’t need the manual after day one.
The ACE 300’s control panel — clean, readable LCD with 6 straightforward buttons.
Ergonomics
At 2.8 lbs, it’s light enough for a full day out without shoulder fatigue. The arm cuff is padded and adjustable. My 10-year-old nephew swings it comfortably — it’s genuinely not heavy. The three-part stem adjusts from 40 to 53 inches, making it suitable for both kids and tall adults.
One honest gripe: when you attach a larger aftermarket coil (like the 9×12 PROformance), the stem joints can feel slightly loose. It’s a known quirk of the ACE series. The included 7×10 coil, however, sits perfectly balanced.
Durability
After 6 months of regular use — including being caught in two rain showers — my unit looks and performs exactly as it did out of the box. The included control box cover (ACE Environmental Cover-Up) protects the electronics from dust and rain, which is a smart design choice given the control box isn’t waterproof itself.
Performance Analysis
Core Functionality — How It Hunts
The ACE 300 is a single-frequency VLF (Very Low Frequency) detector operating at 8 kHz. That frequency sweet spot is genuinely well-chosen. It’s sensitive enough to pick up small gold jewelry and silver coins, while still being stable in moderately mineralized soil. Compare that to the ACE 200’s 6.5 kHz — the jump to 8 kHz makes a real difference on smaller targets.
In my testing at a 1920s-era park in Ohio, the ACE 300 recovered 47 coins in a 3-hour session — including a 1937 wheat penny at roughly 6 inches. That’s impressive for a sub-$300 machine.

Depth & Target ID Performance
Garrett rates the ACE 300 at 8″+ depth. In real conditions on average soil, I consistently detected quarters to about 7–8 inches and bottle caps to 5–6 inches. In looser, sandier soil (like a dry beach), depth improved slightly. In heavy clay soil, depth dropped to 5–6 inches on coins.
The Digital Target ID (0–99 scale) is the star feature here. Once you learn the numbers, you’ll be identifying targets before you dig most of the time:

Discrimination & Iron Resolution
The ACE 300 packs 12 discrimination segments — twice as many as its predecessor, the ACE 250. In trash-heavy sites (old parks full of bottle caps and pull tabs), this matters enormously. You can notch out specific segments while keeping others open, so you’re not digging every rusty nail.
The 3-tone audio system (low grunt for iron, mid beep for mid-conductors like pull tabs, high beep for coins) gets intuitive fast. By week three of testing, I was digging only on the high tone, and my recovery rate jumped significantly.
User Experience
Setup & Assembly – The Garrett Ace 300 metal detector
Assembly takes under 5 minutes. The three-part stem twists together, the coil slots in with a bolt and wing nut, and you snap the coil cable through the stem guides. No tools needed. The cam locks on the stem (an upgrade from older ACE models) keep everything solid.
Daily Use
The turn-on-and-go design philosophy shines here. Power on, pick a preset mode (Coins, Jewelry, or Relics are the most popular), set your sensitivity, and swing. The preset ground balance handles average soil conditions without any tuning. You’re hunting within two minutes of arriving at a site.
Battery life is a genuine strength. I average about 25–28 hours on a set of alkaline AAs. A day out (4–5 hours of hunting) won’t even dent a fresh set.
“I upgraded to the Garrett 300 and found the transition to be smooth. It pulls a little downward on the wrist but other than that, it’s balanced and lightweight with a nice LED display with numerical reference for the target. Until you ‘learn’ the tones and numbers being displayed, dig everything — you’ll find more trash than treasure, but that’s not the detector’s fault. There are several modes for distinguishing types of targets.”
— “Just Jeff” (verified purchaser via Family Handyman)
“Many buyers have praised the ACE 300 for providing a ‘serious’ treasure-hunting experience without requiring a degree in engineering. One customer even joked it ‘paid for itself’ because they found and removed nails that would have punctured their car tires! Parents have also highlighted it as a fun family activity.”

Learning Curve
Most adults are comfortable with the basics after 2–3 outings. Learning to trust the Target ID number and audio tones takes a bit longer — maybe 5–10 sessions — but that’s true of any detector. The included DVD is actually useful for this, covering common target IDs and how to interpret the display.
Best Settings for the Garrett ACE 300 metal detector
One of the most common questions online is about the best settings for the Garrett ACE 300. Here’s what actually works based on six months of real-world testing across different environments.
Parks & Yards
Coin Hunting Mode
Use the Coins preset. Sensitivity at 6–7. This notches out most iron and pull tabs while keeping dimes, quarters, and silver.
Old Homesteads
Relic Mode
Use the Relics preset. Sensitivity at 5–6. Opens up more of the disc pattern to catch buckles, buttons, and old brass.
Beach (Dry Sand)
Custom Mode
Open up Custom mode. Notch out iron segments only. Lower sensitivity to 4–5 to reduce chatter from dry sand minerals.
Trashy Sites
High Disc Mode
Use Custom mode with heavy discrimination. Only dig on ID numbers above 50. Reduces digs — increases quality of finds.
Gold Jewelry
Jewelry Mode
Use the Jewelry preset. Keep sensitivity high (7–8). Gold rings typically hit in the 30–55 ID range — dig those mid-tones!
Competition / Club Hunt
Frequency Shift
Use the frequency adjustment buttons to shift away from interference. Essential when other detectors are hunting nearby.
⚠️ Saltwater beach warning: The ACE 300 does NOT perform well on wet salt sand. The fixed ground balance cannot compensate for high soil mineralization, causing constant false signals. For saltwater beaches, look at the Garrett AT Pro or AT Max instead.

Our Verdict on ACE 300 vs ACE 400
The ACE 400 gets you a bigger DD coil (better in mineralized soil), Iron Audio (a separate tone for iron targets), and a slightly higher frequency for better sensitivity on tiny gold. For $100 more, those are real upgrades — especially Iron Audio, which saves you enormous amounts of digging in trash-filled sites.
But if you’re a beginner, or if you mostly hunt parks, fields, and dry beaches? The ACE 300 hits everything you need. Save the $100 and put it toward accessories (a pinpointer is a game-changer — see section 9).
✅ Choose ACE 300 if: You’re new to the hobby, hunting parks/fields/dry beaches, budget-conscious, or just want to see if you enjoy metal detecting before investing more.
⚡ Choose ACE 400 if: You’re hunting iron-heavy sites, want maximum depth on small targets, or plan to hunt varied ground including mineralized soil.

Best Metal Detector Accessories for the Garrett ACE 300
The right accessories make a huge difference — especially for beginners who want to find more, dig smarter, and enjoy the hobby more. Here are the top picks specifically for the ACE 300.
Garrett Pro-Pointer AT Pinpointer (~$130)
This is the single best upgrade you can make. Once your detector locks onto a signal, the pinpointer narrows it down to the exact spot in the hole. It’s waterproof, vibrates AND beeps, and saves enormous amounts of digging. If you only buy one accessory, make it this.
Garrett ACE Digger ($30–$45)
A good digging tool matters more than you’d think. The Garrett All-Terrain Digger is tough, fits in a holster, and handles everything from soft turf to compacted clay. Your finds will thank you.
Garrett Super Sniper 4.5″ Coil (~$90)
Perfect for trashy sites like old parks where the 7×10 coil picks up too much signal noise. The smaller coil gives you much better target separation — you’ll isolate individual targets in a cluster of junk.
Koss UR-30 Headphones (~$20)
The included ClearSound headphones work fine, but aren’t great. The Koss UR-30 is a well-known community favorite — clear sound, volume control on the cord, and comfortable ear cups. Much better at picking up faint signals.
Garrett Carry Bag (~$30)
Keeps your detector and accessories organized for transport. Much easier than wrestling a disassembled detector into your trunk.
💡 Best starter bundle: ACE 300 + Pro-Pointer AT + Digger. This combination runs about $450–$480 and will serve you for years. Many Amazon listings bundle the Pro-Pointer AT with the ACE 300 for ~$380–$400.

Where to Buy the Garrett ACE 300 metal detector
The Garrett ACE 300 is widely available through major retailers. Here’s where to look for the best deals.
⚠️ Always buy from authorized Garrett dealers to ensure your 2-year warranty is valid. Avoid third-party marketplace sellers with no ratings.

Final Verdict
The Garrett ACE 300 is the detector I’d recommend to every new hunter without hesitation. It’s easy enough not to frustrate beginners, capable enough not to bore you once you get good, and tough enough to last years. For parks, fields, old homesteads, and dry beaches, it’s the right tool for the job at a genuinely fair price. The fixed ground balance and non-waterproof control box are real limitations — but for 90% of what most hobbyists actually hunt, they simply don’t come up.
