Garrett ACE 400
Best Overall
Garrett ACE 400 Metal Detector Bundle
5.0
8.5"x11" DD coil · 10 kHz · Iron Audio
The step-up Garrett ACE, with a bigger DD coil, higher adjustable frequency and Iron Audio, bundled with a Garrett Pro-Pointer AT for faster target recovery - a strong all-around combination of capability, brand trust and bundled accessories from a decades-proven name.
A fully collapsible detector built around an oversized 11-inch IP67 dual coil rated to 10-14 inches of detection depth, powered by a built-in rechargeable battery instead of disposable cells. It folds down to about 17 inches, making it the most travel-friendly machine in this comparison.
A feature-packed detector that pairs a 2x-larger backlit color LCD with a 10-inch Double-D waterproof coil and five hunting modes, giving beach and gold hunters a lot of capability in one lightweight 2.5 lb kit.
A fully submersible all-terrain detector with fast recovery and pro-level discrimination, backed by years of positive coverage from publications and hobbyist field testers alike.
A one-touch NORM mode gets first-time users hunting in seconds, backed by an upgraded DSP chip and a full accessory kit aimed at newcomers to the hobby.
Our Best for Beginners pick: the detector experts recommend most for newcomers, but capable enough for anyone who wants one dependable machine, pairing a genuine target-ID interface with a durable submersible coil, all from a made-in-USA brand.
Our Best Affordable pick: one of the lowest-priced full detectors here, and one of the few with a built-in rechargeable battery good for 35 hours, no bag of disposable 9-volts required.
A budget detector built around one of the largest search coils in this comparison: a 12-inch IP68 waterproof coil paired with a DSP chip and five modes, including a dedicated jewelry setting for beach and gold hunting.
Short on time? These three cover most buyers: our Best Overall HawkSeek HS-X7, which pairs a 2x-larger backlit color LCD and a 10-inch Double-D waterproof coil with five beach-and-gold-ready hunting modes, the SUNPOW OTMD15 as the best affordable pick, and the Garrett ACE 300 for beginners who want a proven, dependable machine without the learning curve.
Metal Detectors 101: How They Work & How to Choose
Understand the category before you buy - what the science actually says, and which specs matter.
Every metal detector promises deep finds and pinpoint accuracy, but the way a machine reads the ground, and how well it separates a nickel from a nail, varies a lot from model to model. Here is how they work, the one trade-off that quietly shapes everything you will find, and the features actually worth comparing.
What does a metal detector actually do?
A metal detector sends an electromagnetic field down into the ground through its search coil. When that field crosses a piece of metal, the metal creates its own tiny field in response, and the detector senses the difference and tells you something is there. From that response it works out roughly how deep the target sits and what kind of metal it is likely to be.
It reads the strength and timing of the returning signal to estimate depth and size.
It assigns a Target ID, usually a number on the display, that hints at whether you have hit iron, foil, a coin, or something more valuable.
It lets you set search modes so you can hunt everything or filter for specific kinds of metal, and a pinpoint mode narrows the exact spot before you dig.
Most detectors in this lineup show a Target ID on a digital or backlit LCD, from the Garrett AT Pro to the SUNPOW OTMD15, so you get a read on a target before your shovel ever touches the dirt.
The one trade-off that shapes everything: operating frequency
Here is the thing most first-time buyers never hear. The single most important number on a detector is its operating frequency, measured in kHz, and it sets the whole character of the machine. Lower frequencies, in the single-digit kHz range, push their field deeper into the soil and respond best to larger, high-conductivity targets like silver coins and old relics. Higher frequencies do not reach as deep, but they are far more sensitive to small, low-conductivity targets, which is exactly what gold flakes, thin chains, and fine jewelry are.
That is why a machine tuned for coin and relic hunting is not the same tool as one tuned for gold. Several detectors here, including the Garrett ACE 400 with its adjustable frequency, let you shift that balance to match what you are chasing. If you mostly want coins and buried relics in a park or field, lean toward the deeper, lower-frequency setup. If you dream of gold and jewelry on the beach, sensitivity to the small stuff matters more than raw depth. Match the frequency to the target and you will dig far less junk to find the same treasure.
Which specs actually matter?
Once you understand frequency, a few features decide which detector fits your hunts:
Discrimination: This is what keeps you from digging trash. Discrimination reads the Target ID and lets you ignore whole classes of metal, like iron and pull-tabs, so the machine stays quiet on junk. Most models here offer it through modes such as the SUNPOW OTMD15's Disc and Notch settings.
Ground balance: Mineralized soil, wet salt sand, and iron-rich dirt all confuse a detector and cause false beeps. Ground balance cancels out that background so real targets stand out, which matters most on the beach and in heavily mineralized ground.
Search coil size and type: A larger coil like the 8.5 inch by 11 inch Double-D on the Garrett AT Pro and ACE 400 covers more ground and reaches deeper, while a smaller coil like the 7 inch by 10 inch on the Garrett ACE 300 is nimbler around trash and easier to pinpoint with. Double-D coils, common across this lineup, handle mineralized soil better than concentric ones.
Waterproofing: A waterproof coil lets you hunt wet sand and shallows where jewelry collects. Note the difference between a waterproof coil and a fully submersible machine: the Garrett AT Pro goes fully under to 10 ft, while most models here waterproof only the coil, so keep the control box dry.
Search modes and Target ID: More modes, from all-metal to notch to a beginner-friendly NORM mode, give you finer control, and a clear numeric Target ID on the display saves you from digging blind.
Weight and power: You will swing this for hours, so weight matters, ranging from about 2.5 lbs up to 6.6 lbs here. A rechargeable lithium model like the SUNPOW OTMD15 skips the cost of constant AA or 9V replacements.
How we grade products
Graded Picks rankings are aggregated from several independent signals: verified buyer ratings and the size of the review base for credibility, recent monthly purchase volume for relevance, assessments from trusted metal detecting and hobbyist publications, and how each product places in leading category lineups. For metal detectors we weigh:
Detection depth and target separation
Discrimination and ground balance capability
Coil size, type, and waterproofing
Target ID accuracy and display clarity
Range and usefulness of search modes
Weight, comfort, and battery life
Overall value for the price
Permission and rules note: Before you detect anywhere, check local laws and get permission. Many public parks, beaches, and historic sites restrict or ban detecting, and digging on private land without the owner's consent can be trespassing. Federal and protected sites often prohibit it outright, and disturbing archaeological or historical material may be illegal. When in doubt, ask first, fill every hole you dig, and leave the ground as you found it.

Garrett ACE 400
Best Overall
1. Garrett ACE 400 Metal Detector Bundle
5.0
The ACE 400 sits between the ACE 300 and the AT Pro, and this listing bundles it with Garrett's Pro-Pointer AT, the pinpointer serious hunters consider near-essential. Over the ACE 300 it adds a larger 8.5" x 11" DD coil, a higher 10 kHz adjustable frequency, Iron Audio (a distinctive grunt that flags iron junk) and enhanced iron resolution, letting it hunt a bit deeper and separate targets better in cluttered ground. Reviewers call it a strong middle-ground machine that stays beginner-friendly, while noting the same limitation as its sibling: fixed ground balance makes mineralized ground and wet salt sand a struggle. For a park-and-field hunter who wants more capability than the ACE 300 without the AT Pro's price or learning curve, plus a bundled pinpointer in the box, it's a well-rounded Garrett pick with a decades-proven track record behind our Best Overall HawkSeek HS-X7 above - buyers who want the lowest price should see our Best Affordable SUNPOW OTMD15, and first-timers should start with our Best for Beginners Garrett ACE 300.

Power source4x AA batteries (included)
Item weight2.9 lbs
Warranty2 years (Garrett limited)
Pros
Strong all-around combination of capability, brand trust and bundled accessories
Larger 8.5" x 11" DD coil hunts deeper than the ACE 300
Higher 10 kHz adjustable frequency plus Iron Audio
Bundled with the Garrett Pro-Pointer AT pinpointer
Stays easy to use for beginners and intermediates
Cons
Fixed ground balance struggles on mineralized ground and wet salt sand
Coil is submersible but the housing is not fully waterproof
Priced above the ACE 300 for a modest capability step-up
Who is it for?
Park-and-field hunters who want more depth and target separation than the ACE 300 plus a bundled Pro-Pointer AT, without the AT Pro's price or complexity, from an established, decades-proven brand.
Who is it not for?
Beach and saltwater hunters who need fully submersible housing and manual ground balance (the Garrett AT Pro fits that better), and buyers who just want the simplest, cheapest way to start (see our Best for Beginners ACE 300 or Best Affordable SUNPOW OTMD15).
2. ABLEGRID GC-1021 Rechargeable Foldable Metal Detector
4.9
The GC-1021 is ABLEGRID's foldable take on a full-size detector, collapsing from a 56.69-inch hunting length down to about 17.32 inches for a backpack or car trunk, something none of the telescoping-only machines in this comparison can match. Its 11-inch IP67 dual coil is rated for 10 to 14 inches of detection depth, among the deepest claims in this lineup, and runs through an upgraded DSP chip across five modes (All Metal, Discrimination, Notch, Memory and Pinpoint) with 0-99 target ID and six-way metal identification shown on a backlit LCD. A built-in 1800mAh lithium battery is rated for about 12 hours per charge and supports USB-C and power-bank charging, so there's no bag of disposable 9-volts to carry. An independent portable-detector buying guide lists it among its picks for hobbyists who want a compact kit, and a hands-on video walks through its fold-and-go design. As a newer entrant it has far less accumulated buyer and independent-test history than the Garrett machines in this comparison, so treat the deep-detection claim as a best-case figure rather than a guarantee.
Power sourceRechargeable lithium, 1800mAh (12 hr, USB-C)

Five modes plus six-way metal ID and 0-99 target ID on a backlit LCD
Featured in an independent portable-detector buying guide
Cons
Far smaller buyer base and less independent testing than the Garrett or SUNPOW machines here
Only the coil is IP67 rated; the control box and folding joints are not meant for submersion
Only a 1-year warranty, shorter than several rivals in this comparison
Who is it for?
Buyers who want the most compact, travel-friendly detector in this comparison and like the convenience of a rechargeable battery over disposable cells.
Who is it not for?
Anyone who wants a long-established brand with years of accumulated independent testing, such as the Garrett machines here, or who needs a fully submersible housing.
A standout alternative to our Best Overall pick. The HawkSeek HS-X7 tops this comparison on the strength of real feature-for-the-money value: a 2x-larger backlit color LCD, a 10-inch Double-D waterproof coil, an advanced DSP chip and five modes (All-Metal, Disc, Jewelry, Memory and Pinpoint) that cover both beach and gold hunting. It ships as a full kit with a folding shovel, headphones and a carry bag, runs on two included 9V batteries and stays easy to swing at about 2.5 lbs. One honest caveat: it is a newer brand without the long field-testing history of the Garrett machines elsewhere in this comparison, so buyers who specifically want a decades-proven track record above all else should consider the Garrett ACE 300, AT Pro or the ACE 400 Bundle, and those who want a built-in rechargeable battery instead of disposable 9-volts may prefer our Best Affordable SUNPOW OTMD15.

Who is it for?
Most buyers: our Best Overall pick for a large color display and a full accessory kit at a fair price, even from a newer brand.
Who is it not for?
Anyone who specifically wants a decades-proven track record above all else, such as the Garrett ACE 300, AT Pro or ACE 400 Bundle in this lineup, or a rechargeable battery.
The AT Pro has earned years of sustained praise from expert and hobbyist field testers in the all-terrain class. Its 15 kHz operation, fast recovery speed and pro-mode discrimination let it separate good targets from trash in cluttered parks and beaches, and testers routinely report coins at 8 to 10 inches and relics deeper. The headline feature is that the entire unit is submersible to 10 feet, so you can wade creeks and shallow surf that would sideline a coil-only-waterproof detector, and Iron Audio's distinctive junk-rejection tone speeds up sorting real targets from trash. Reviewers note it isn't optimized for saltwater wet sand like a multi-frequency machine, but for all-around land and freshwater hunting it delivers performance that punches well above its price, backed by Garrett's made-in-USA reputation and a 2-year warranty.

Pro-mode discrimination and Iron Audio for junk rejection
The Horizon X6 is a newcomer-friendly detector built around its NORM mode (our Best for Beginners pick is the Garrett ACE 300), designed to get a brand-new user swinging and finding targets within seconds, without touching a settings menu, alongside five more specialized modes (All-Metal, Disc, Memory, Jewelry, Pinpoint) for once someone is ready to dig deeper into the hobby. SuperEye's upgraded DSP chip is pitched as improving detection accuracy and cutting false signals versus the brand's earlier boards, and reviewers testing it have reported locating coin-sized targets around 10 inches deep with consistent results. It ships as a complete kit with a folding shovel, headphones and a carry bag, and assembly is tool-free in about a minute. As a newer brand it has far less accumulated field-testing history than the Garrett detectors in this comparison, and its smaller buyer base means less real-world durability data exists so far, but early hands-on coverage has been positive for a first detector.

Our Best for Beginners pick. The Garrett ACE 300 does what almost no other detector in this comparison manages: it gives newcomers a genuinely serious treasure-hunting experience without a steep learning curve, while staying capable enough that plenty of experienced hunters keep one in the truck. Testers at major publications, including Family Handyman, name it their entry-level pick, and field reviewers report consistent target acquisition across soil types with coin-depth of roughly 6-8 inches and larger objects deeper still. You get a 7" x 10" submersible PROformance coil, an 8 kHz frequency, digital target ID, five search modes plus pinpoint, and adjustable iron discrimination, features usually reserved for pricier machines. It runs on four AA batteries for 20-40 hours, weighs under 3 pounds, and is backed by Garrett's made-in-USA reputation and a 2-year warranty. For a first detector or an everyday workhorse, it's a dependable choice that won't leave you outgrowing it in a season.

Serious beach and saltwater hunters who need a fully submersible housing and manual ground balance.
The SUNPOW OTMD15 is our Best Affordable pick, pairing one of the lowest prices in this comparison with a feature budget detectors almost never include: it charges instead of eating disposable 9-volt batteries, with a built-in lithium pack rated for about 35 hours per charge. You get a 10-inch Double-D deep-search coil built to filter out mineralized chatter, four modes (All-Metal, Disc, Notch and Pinpoint), and a backlit LCD, in a package aimed at beach, saltwater and yard use. Reviewers describe it as surprisingly accurate and easy to adjust for a machine at this price, with solid depth for the money. It carries a 1-year warranty. Like other budget detectors it won't match a Garrett for recovery speed, but as a low-cost, low-hassle entry point it's a genuine value.
8. Gbnryg M55Z Metal Detector (12" Waterproof Coil)
4.5
The Gbnryg M55Z leads with coil size: its 12-inch IP68 waterproof search coil is larger than every other detector in this comparison, giving it a wider sweep per pass for covering ground quickly. An upgraded DSP chip and five modes - All Metal, Disc, Memory, Jewelry and Pinpoint - run through a backlit LCD, with the Jewelry mode specifically tuned for gold and fine-jewelry hunting on the beach. The collapsible shaft adjusts to fit users of different heights, and it ships as a complete kit with two batteries, a carry backpack, over-ear headphones and a digging tool, matching the bundled-kit format of other budget entries here. It ties the SUNPOW OTMD15 for one of the lowest prices in this comparison, though it comes from a newer, less familiar manufacturer without the accumulated buyer history of the Garrett or DR.OTEK names. The manufacturer backs it with a lifetime warranty.
