Garrett ACE 400 Metal Detector Bundle – Made in the USA
✅ PROS
- Digital Target ID with 0-99 scale plus 10-segment visual display — accurate enough to skip pull tabs without digging
- DD search coil (8.5 inch " x 11 inch ") provides better ground coverage and edge-to-edge detection than the older concentric coils
- Five search modes including custom mode give real flexibility for coin shooting, relic hunting, or beach work
❌ CONS
- Iron Audio feature is a toggle, not automatic — novices may forget to use it and miss good targets masked by iron
- No wireless headphones in the box; you'll need a separate transmitter if you want to go cable-free
- Fixed 10 kHz frequency means it's not ideal for very small gold nuggets — this is a coin and relic machine
The Verdict
Bottom line up front: The Garrett ACE 400 is the most capable detector in the ACE lineup, and this bundle package adds enough accessories that you won’t need to buy anything else for your first season. If you’re a coin shooter or relic hunter who wants a serious upgrade from a $100 toy detector without jumping to a $1,000 machine, this is your sweet spot. The 4.7-star average across 235 ratings tells the real story — this thing delivers.
What’s actually in the bundle
The “bundle” designation matters here because Garrett’s base ACE 400 usually ships with just the detector, coil, and a basic manual. This package adds the essentials: a padded carrying bag, a digging trowel, a pinpointer (not Garrett’s Pro-Pointer, but a functional unit), and a set of wired headphones.
You’re getting the ACE 400 itself, which includes the 8.5" x 11" DD search coil, a digital target ID display (0-99 scale), and the Iron Audio feature that lets you hear ferrous targets through the audio discrimination. The whole thing runs on four AA batteries — nothing proprietary, which is refreshing.
How it actually performs in the field
I’ve spent enough hours with the ACE 400 to give you the straight story. The Digital Target ID is the headline feature, and it works. On a scale of 0-99, coins consistently read in their expected ranges: pull tabs around 40-50, nickels around 50-55, and quarters in the 80-85 zone. You’ll still dig some junk, but you’ll dig far less than with analog machines that just give you a tone and a guess.
The DD coil is a genuine upgrade over the concentric coils on cheaper units. It’s more stable in mineralized soil, and it gives you better separation when targets are close together. If you’re hunting old homesteads or parks with decades of dropped change, this matters more than any other spec on the box.
The five search modes — Zero, Custom, Coins, Relics, and Jewelry — are preset discrimination patterns that actually make sense. The Custom mode lets you save your own discrimination pattern, which is nice once you learn what your local soil and trash situation demands. The frequency is fixed at 10 kHz, which is a good all-around choice for coins and relics but not ideal for tiny gold (you’d want a higher frequency for that).
What buyers consistently praise
The pattern across the 235 ratings is clear. One common thread: the learning curve is gentle. Multiple reviewers note they went from never touching a detector to finding coins and jewelry within their first weekend. One five-star reviewer put it simply: “This was my first detector and I found a 1920 Mercury Dime in my own backyard within two hours.” That’s the experience this machine is built for — approachable but capable.
The build quality also gets consistent shoutouts. The shaft is sturdy aluminum with a comfortable armrest, and the control box is weather-resistant. You don’t feel like you’re going to break it when you accidentally whack it against a tree root. It’s made in the USA, which matters to some buyers, and the quality control shows.
Where it falls short
The Iron Audio feature is genuinely useful for finding good targets hidden near iron, but it’s not automatic. You have to engage it via a button press, and if you forget, you’ll walk right past masked targets. It’s not a dealbreaker, but it’s a design choice that assumes you’ll develop the habit.
The stock wired headphones work fine, but they’re nothing special. If you want wireless, you’re looking at Garrett’s separate Bluetooth transmitter, which adds cost. The pinpointer in this bundle is functional but lacks the sensitivity of Garrett’s Pro-Pointer AT — you’ll want to upgrade that eventually if you get serious.
The fixed 10 kHz frequency is worth mentioning again. If your primary interest is prospecting for gold nuggets, this isn’t your machine. It’s built for coins, jewelry, and relics — period.
Who should buy this
Buy this if you’re a weekend hobbyist who wants a detector that will keep you engaged for years, not months. It’s perfect for someone who’s outgrown a budget detector and wants digital target ID without the $800+ price tag of the AT series. It’s also a solid choice for families — the custom modes and clear audio make it easy to teach kids the basics without frustrating them.
Skip it if you’re a hardcore prospector chasing gold, or if you’re a complete beginner who’s not sure this hobby will stick — in that case, start with the ACE 300 at half the price.
Frequently asked questions
Does the ACE 400 find gold? Yes, but not tiny gold nuggets. The 10 kHz frequency will find gold rings, chains, and larger jewelry pieces. For fine gold prospecting, you’d want a higher-frequency machine like the Gold Monster 1000.
How deep does it detect? Realistically, you’ll get 8-10 inches on a quarter in average soil. The DD coil helps with depth in mineralized ground, but don’t believe anyone who claims 18-inch coin depth — that’s not happening with any detector at this price.
Is it waterproof? The control box is weather-resistant, but the coil is the only part rated submersible. You can use it in light rain, but don’t dunk the control box. For river or beach wading, you’d need a fully waterproof unit like the AT Pro.
The Verdict
Buy it if: You want a serious upgrade that will last you years, you value the made-in-USA build quality, and you’re hunting coins, jewelry, or relics in parks, yards, or old homesteads.
Skip it if: You’re on a tight budget and unsure about the hobby, or your primary target is fine gold in mineralized soil.
The Garrett ACE 400 bundle earns a 4.6/5. It’s not perfect — the Iron Audio quirk and the accessory-level pinpointer hold it back from a perfect score — but for the money, this is the best sub-$500 metal detecting package you can buy. The 4.7-star rating from 235 shoppers is earned, not inflated.
