Best Metal Detector for Nails and Bottle Caps

Quick comparison

Why these five made the cut

Bottle caps show up where people sit, eat, and gather. Nails show up around old sheds, fences, home sites, and repairs. In both cases, the detector has to do more than beep. It has to keep junk from sounding too much like a keeper.

That is why this list favors detectors that fit different kinds of trashy ground:

• The Equinox 900 covers the broadest range of mixed sites.
• The ACE 400 gives budget buyers a straightforward way in.
• The AT Pro is the strongest specialist pick for old, ugly ground.
• The Simplex Lite keeps things manageable for new hunters.
• The Tracker IV works well as a simple casual or backup machine.

1. Minelab Equinox 900

The Minelab Equinox 900 is the best overall choice because it fits the widest range of trashy places. If your hunts move between parks, beaches, and fields, this is the one that keeps up without forcing you into a narrow use case. Its current package also includes a 6-inch coil alongside the 11-inch coil, which gives it a ready answer for nail beds and tight trash.

It makes the most sense for hunters who want one detector that can handle mixed ground and mixed junk without feeling underpowered. It is the strongest pick when your sites change often and you do not want to own a different detector for every location.

The trade-off is simple: this is more detector than a casual backyard user usually needs. If you hunt only a few times a year or stay in mild ground, the extra capability may sit unused.

Choose the Equinox 900 if you want the most flexible option here and you expect to keep running into nails, caps, and other trash in different kinds of sites.

2. Garrett ACE 400

The Garrett ACE 400 is the best value pick for hunters who want solid discrimination without a steep learning curve. It gives budget-minded buyers a cleaner way to get started without jumping straight into a more advanced machine.

Garrett’s ACE 400 page lists Iron Audio, which lets you hear discriminated iron that is normally silenced so you can avoid digging flat iron trash, along with an adjustable 10 kHz frequency and an 8.5 by 11 inch DD searchcoil. Garrett’s separate ACE 400i page is titled the International Version, so this guide names the U.S. model, the ACE 400.

This is a good fit for mild ground, open parks, and casual hunts where you still want to sort common trash without a complicated setup. It is easier to live with than a more technical detector, which matters if you are still learning how trashy ground sounds.

The downside is that it has less room to work when the site gets ugly. In old lots and dense iron, the ACE 400 gives up some of the nuance that more specialized detectors can offer.

Pick the ACE 400 if you want a straightforward detector that does the job without asking for a big learning curve.

3. Garrett AT Pro

The Garrett AT Pro is the specialist pick for city parks and old lots where nails and bottle caps dominate. It belongs in places where a basic detector starts to feel vague and every signal needs a little more sorting.

This is the one to look at if your hunting spots are full of old trash and you want a machine that feels built for that kind of work. It suits hunters who are willing to listen carefully and work through noisy ground instead of expecting the detector to sort everything out for them.

The trade-off is the learning curve. The AT Pro gives more to work with, but it asks for more attention in return.

Choose the AT Pro if most of your time is spent in old, trash-heavy sites and you do not mind learning a detector that rewards patience.

4. Nokta Simplex Lite

The Nokta Simplex Lite is the best easy-entry option for beginners who want a manageable detector for everyday trash hunting. It replaces the older Simplex+ on this list: Nokta now sells a New Generation Simplex line, and Nokta lists the Simplex+ as discontinued. The Lite is the entry model of the three, with four search modes (Field, Park, Beach and All Metal), a 24 x 15 cm double-D coil, 15 kHz operation, and notch discrimination with an iron-off setting, per Nokta’s comparison chart .

This model fits casual park use, basic yard hunting, and the kind of everyday trash hunting that new users run into first. It weighs 1.2 kg (2.6 lbs) per Nokta , which keeps long sessions manageable.

Its weakness is that it is not the most specialized answer for the roughest iron patches, and it has fewer controls than the BT and Ultra (no Bluetooth, and the Ultra adds recovery speed and tone controls). If your usual sites are already known to be packed with nails and bottle caps, you may outgrow it sooner.

Pick the Simplex Lite if you want an easy first detector and you expect your hunts to stay fairly ordinary.

5. Bounty Hunter Tracker IV

The Bounty Hunter Tracker IV is the best casual backup pick for backyard checks and picnic-area hunts. It is simple, easy to get swinging, and well suited to short sessions where you do not want to spend time learning a more complex machine.

This is a good fit for occasional use, loaner duty, or very basic hunting in easy ground. If you only head out now and then, the Tracker IV keeps things plain and fast.

The limitation shows up quickly in trash. It does not have much room to sort tightly packed junk, so nail-heavy and bottle-cap-heavy sites can outgrow it fast.

Choose the Tracker IV if you want a straightforward detector for light use and do not expect to spend much time in rough trash.

Discontinued: Minelab Equinox 800

Minelab lists the Equinox 600 and 800 as discontinued, and the Equinox 900 is its current replacement for the 800. If you want to stay in the Equinox line for less than the 900, the current step-down is the Equinox 700 , which Minelab rates waterproof to 5 m (16 ft) and sells with an 11-inch double-D coil and wireless headphones (Minelab Equinox 700 page ). If you are weighing a used 800 anyway, check the battery, seals, shaft locks, and coil before paying. Our Equinox 800 review covers what to inspect, and the Equinox 800 vs 900 comparison explains when the savings are worth it.

What Matters in Dense Iron

Target separation matters more than a deep air-test number. In a nail bed, the useful controls are recovery speed (fast enough to reset between close targets), iron audio or an iron bias setting, and coil size. A 5- to 6-inch coil with high recovery speed and light discrimination suits square nails, cellar holes, and demolition lots; a 6.5- to 8-inch coil suits mixed iron and modern trash; an 8- to 11-inch coil suits open ground with scattered rust, at the cost of more masking in tight patches.

Keep discrimination light, because heavy notch settings hide good targets along with bad ones. Swing low and level, slow down, and check a signal from 90 degrees, since a keeper next to iron often sounds cleaner from one direction. Target ID jumps around near rust, so trust repeatable audio first and use the number to confirm.

How to narrow it down

If you are choosing between these five, start with the places you actually hunt most often.

• Mixed parks, beaches, and fields: go with the Equinox 900
• Budget-friendly and easy to learn: go with the ACE 400
• Old lots and city parks with lots of junk: go with the AT Pro
• First detector for everyday trash hunting: go with the Simplex Lite
• Backyard and picnic-area use only: go with the Tracker IV

That is the cleanest way to shop this list. The wrong detector can still work, but it wastes more time in trashy ground.

Our Garrett ACE 400 review (published under the 400i name) covers the budget pick on this list in more detail.

Best pick for most people

The Minelab Equinox 900 is the best metal detector for nails and bottle caps for most buyers because it covers the broadest range of trashy sites. If you move between parks, beaches, and fields, it is the most complete option here.

If you want a lower-cost start, the Garrett ACE 400 is the easier value buy. If your hunting is mostly in old, junk-filled city sites, the Garrett AT Pro is the most focused choice. If you want a beginner-friendly detector that still feels like a real upgrade, the Nokta Simplex Lite is the easiest entry point. If you only need something simple for casual outings, the Bounty Hunter Tracker IV is enough. If you want to stay with Minelab’s Equinox line below the 900, the current Equinox 700 replaces the discontinued Equinox 800 as the step-down option.

Recovery Gear for Iron-Heavy Sites

Iron-heavy ground means more holes. A quick pinpointer, a digger that cuts roots and a pouch with a separate place for trash are the first extras to add.
