Best Metal Detector for Coins 2026: Target ID, Iron Audio & Small Coils Ranked

Quick Answer: The best metal detector for coins in 2026 is the Minelab Equinox 900 ($999) — 119 target ID segments, eight levels of recovery speed, and the small 6-inch EQX06 coil included in the box, which is the part that actually separates a coin from the nail beside it. On a budget, the Nokta Double Score ($349) and Minelab X-TERRA PRO ($294.99) are the value picks, and the Garrett ACE 400 ($357.99) is the one to buy for iron-infested turf because of its Iron Audio — a feature Garrett’s own comparison table lists as absent on the cheaper ACE 300. Coin hunting is won on target ID resolution and iron handling, not on depth.

Coin shooting is the most common kind of metal detecting and the most poorly served by spec sheets. Every listing shouts about depth, but the coin you are missing in a hundred-year-old park is almost never too deep — it is sitting four inches down with a rusted nail two inches to its left, and your machine is averaging the two into one meaningless grunt. That problem is solved by target ID resolution, adjustable recovery speed, honest iron audio, and a coil small enough to see one target at a time. Below are the seven machines that do it best in 2026, at manufacturer-verified prices, plus the two popular picks we deliberately do not recommend for coins.

Our top picks at a glance

Prices are manufacturer list prices verified in July 2026 where the manufacturer publishes one; dealer street prices vary in both directions. The Equinox 700 is $699 direct from Minelab but $749 at both Kellyco and Detector Warehouse, and the X-TERRA PRO ranges from $269.99 to $320 depending on the dealer — always check two before you buy.

1. Minelab Equinox 900 — Best Overall for Coins

The Equinox 900 is the coin hunter’s machine because it wins on the two things coin sites actually demand. First, resolution: 119 ID segments from -19 to 99 means the difference between a wheat penny and a pull-tab shows up as separate, repeatable numbers rather than a shared blur. Second, separation: recovery speed is adjustable across eight levels, so when the coil crosses a coin and a nail in the same sweep the machine can finish processing the first before the second arrives. Minelab documents Park 1 as its “General / Coins” mode, tuned for modern coins and larger jewellery with a default pattern that rejects foil-like targets.

The bundled EQX06 6-inch coil is the underrated part of this purchase. On the Equinox 700 you get the 11-inch coil only; on the 900 the small coil is in the box. In an old picnic area littered with a century of bottle caps, that 6-inch coil is worth more than any depth advantage, because it puts fewer targets under the coil at once. This is the machine our main rankings put at the top of the sport, and for coins specifically nothing at any price does the job more cleanly.

2. Nokta Double Score — Best Value

The $20 between the Nokta Score ($329) and the Double Score ($349) is the best-spent twenty dollars in the entire category, and for coin hunting it is not optional. According to Nokta’s own comparison chart, the base Score has no adjustable recovery speed and no notch discrimination — the two settings that let you pick a coin out of iron and screen out a specific junk range. The Double Score adds both, plus an iron filter. Buy the base Score and you have a multi-frequency machine that cannot be told what to ignore.

Be aware of one naming mess when you shop: dealers variously list this machine as “Double Score”, “Score 2” and “Double Score 2”. They are the same $349 detector with the same SC30 coil — there is no third model. Also note that both Score models carry 60 target IDs, not the 99 on the Simplex ULTRA and the Legend 2, a spec gap that dealer listings routinely blur. Sixty is plenty to hunt coins with; it is simply not the 99 you may think you are buying. Full lineup context is in our Nokta guide.

3. Minelab X-TERRA PRO — Best Under $300

The X-TERRA PRO is the cheapest way to get Minelab’s full 119-segment ID scale, which is exactly the spec coin hunting rewards. It is a single-frequency machine rather than simultaneous multi-frequency, so it gives up ground on wet salt sand and on the deepest mixed targets — but on dry park turf, where almost all coin hunting happens, the frequency choice matters far less than the ID resolution and the 30 discrimination segments you get to shape. At $294.99 from Minelab it is the value benchmark of 2026. Shop it carefully: we found the same machine at $269.99 at Kellyco and $320 at Detector Warehouse in the same week. It sits comfortably alongside the machines in our beginner rankings.

4. Garrett ACE 400 — Best for Iron-Filled Turf

If your coin sites are old home lots, farm edges or anywhere a barn once stood, iron is the enemy and the ACE 400 is the sub-$400 answer. Garrett’s own product comparison lists Iron Audio as “No” on the ACE 300 ($269.99) and yes on the ACE 400 — that single feature is most of the $88 between them, and for coin hunting it is worth it. Iron Audio plays the discriminated iron back to you at a low tone instead of silencing it, so a coin sitting beside a nail sounds like a coin with a nail rather than like nothing at all. The 10 kHz frequency and DD coil help further in mineralised soil.

One honest caveat before you buy: Garrett publishes no waterproof depth rating for the ACE series at all. Dealers describe the search coil as waterproof, but the control box is not, and no manufacturer figure exists to quote. If you expect to hunt creek edges, skip to the AT Pro or the Simplex ULTRA. The rest of the lineup is decoded in our Garrett guide.

5. Nokta Simplex ULTRA — Best Waterproof Coin Machine

Creeks, old swimming holes and river fords are some of the best coin ground there is, and they are where most $300 machines stop. The Simplex ULTRA is rated IP68 to 5 m — identical to the Legend 2 at $999 and to the Equinox 900 at $999. That is Nokta’s defining pattern: the waterproof rating does not scale with the price. You also get 99 target IDs (more than either Score model), adjustable recovery speed and notch, which is a genuinely capable coin toolkit for $299. What you give up is simultaneous multi-frequency; it is a 15 kHz single-frequency machine, which is fine in fresh water and dry ground and weaker on wet salt sand. For salt work see our beach rankings and our waterproof spec guide.

6. Minelab Equinox 700 — Step-Up Multi-Frequency

The 700 gets you into the Equinox platform for $300 less, and for open-field coin hunting it loses very little. The gap opens exactly where trashy coin sites live: three recovery-speed levels instead of eight, and no 6-inch coil included. Add the EQX06 separately and you are close enough to the 900’s price that most coin hunters should simply buy the 900. Buy the 700 if your sites are clean pasture and plough soil rather than century-old picnic grounds. Note the pricing quirk we verified in July 2026: Minelab lists it at $699 while Kellyco and Detector Warehouse both hold at $749 — buy direct and save fifty dollars.

7. Garrett AT Pro — Best for Creeks & Wet Ground

The AT Pro has been the American creek-and-relic standard for over a decade and it remains a strong coin machine wherever the ground is wet. Its 40 iron discrimination levels are unusually granular for a machine at this price, which pays off in old sites where you want to reject square nails without rejecting a silver dime. Pro Mode audio, which varies tone strength with target strength, is the feature experienced users cite most. Two notes of honesty: Garrett’s own product pages publish neither the operating frequency nor the weight of the AT Pro — the widely quoted 15 kHz and 3.03 lb come from dealer listings, not from the manufacturer — and recovery speed is marketed as fast but is not a setting you can adjust.

The two coin picks we do not recommend

Minelab Vanquish 540. It is the only detector in this comparison with a search mode literally named “Coin”, and it is still the one to avoid in July 2026. It was sold out at Detector Warehouse when we checked, Kellyco’s Vanquish listing now serves the newer Vanquish 560 at $399, and the 540’s waterproofing is coil-only to 1 m with a merely water-resistant control box. Minelab has announced no discontinuation, so treat this as a supply signal rather than an obituary — but a machine you cannot reliably buy is not a recommendation.

Garrett ACE 300. At $269.99 it looks like the value play against the $357.99 ACE 400, and for open grass it is a fine first detector. For coin hunting specifically it is the wrong economy: no Iron Audio, 8 kHz instead of 10 kHz, and a concentric coil instead of DD. If your budget stops at $300, the X-TERRA PRO at $294.99 gives you 119 ID segments and an IP68 5 m rating for less money than the ACE 400. Our budget rankings cover the sub-$200 tier.

When the answer is not a new detector

If you already own a capable machine and you are not finding coins in a hunted-out park, the upgrade is almost never a new detector — it is a smaller coil. Garrett states the relationship plainly: “a 4-inch coil might locate a standard-size coin, like a quarter, at a depth of 4 inches, while a 12-inch coil could find the same coin at a 12-inch depth.” You trade depth for separation, and in a site where every coin has three pieces of trash beside it, separation is what you are short of. A 6-inch aftermarket coil typically costs a fraction of a new machine and transforms a picked-over park. Pair it with a pinpointer and a proper digging tool and your recovery rate climbs before your machine ever needs replacing.

Coin detecting by the numbers

• 119 target ID segments (-19 to 99) is the resolution on the Minelab Equinox 700, Equinox 900 and X-TERRA PRO, versus 60 segments on both Nokta Score models and a 0–99 scale on the Garrett ACE and AT lines (manufacturer specifications, 2026).
• Recovery speed is adjustable across eight levels on the Equinox 900 but only three on the Equinox 700 — the single clearest reason to pay the $300 difference if you hunt trashy ground (Minelab, 2026).
• Garrett lists Iron Audio as “No” on the ACE 300 and yes on the ACE 400 in its own product comparison, alongside 8 kHz vs 10 kHz and concentric vs DD coils (Garrett, 2026).
• The base Nokta Score has neither adjustable recovery speed nor notch discrimination, both of which the $20-dearer Double Score adds, per Nokta’s published comparison chart (Nokta, 2026).
• IP68 to 5 m (16 ft) is the rating on every Nokta in this guide and on both Equinox models, while Garrett publishes no waterproof rating whatsoever for the ACE series and rates the AT Pro to 3 m (10 ft) (manufacturer specifications, 2026).
• No manufacturer publishes a typical burial depth for US coins. The often-repeated “top six inches” figure traces to hobby forums, not to Garrett, Minelab or Nokta; what Garrett does publish is that detection depth scales with coil diameter (Garrett, 2026).

How to choose a coin detector

• Buy ID resolution before you buy depth. Coin sites fail you through masking, not distance. 119 segments beats 60, and both beat a machine with a needle and four notches.
• Insist on adjustable recovery speed. It is the setting that separates a coin from an adjacent nail. If a machine does not have it — like the base Nokta Score — it is not a serious coin machine at any price.
• Check whether a small coil is included or extra. The Equinox 900 includes a 6-inch coil; the 700 does not. Price the coil in before you compare the two.
• Only pay for waterproofing you will use. Park turf never needs it; creeks and swimming holes absolutely do, and there the published rating matters — Garrett gives none for the ACE line.
• Verify the price at two dealers. We found the X-TERRA PRO between $269.99 and $320 and the Equinox 700 $50 cheaper direct from Minelab than at either major dealer, in the same week.

The bottom line

For coin hunting in 2026 the Minelab Equinox 900 at $999 is the machine to beat: 119 ID segments, eight recovery-speed levels, and the 6-inch coil in the box that turns a picked-over park back into a productive site. Under $400, the Nokta Double Score ($349) is the smart buy — never the base Score — and the X-TERRA PRO ($294.99) delivers the flagship ID scale for under $300. Choose the Garrett ACE 400 ($357.99) if your ground is full of iron, and the Nokta Simplex ULTRA ($299) if it is full of water. Whatever you pick, read the main detector rankings for cross-brand context and the beginner’s guide for the technique that actually puts coins in the pouch — the machine is only ever half of it.
