Best Metal Detectors for Beaches: Which One to Buy

For saltwater beaches, a waterproof multi-frequency detector such as the Minelab Equinox 900 or the XP Deus II is the strongest choice, a Minelab Equinox 700 or Vanquish model is the sensible step down for newer hunters, and a single-frequency waterproof machine such as the Garrett AT Pro is better suited to dry sand, freshwater and inland sites than to wet salt sand.

Beaches are among the hardest places to detect. Wet salt sand is conductive and makes many detectors chatter, targets can sit under a layer of moving sand, and the best finds are often in the surf zone where the detector must be fully waterproof. This guide explains what to look for, compares the machines reviewers name most often for beach use, and gives a decision table and answers to the questions beginners ask. Specs come from the makers where available, and reviewer opinions are labelled as such.

What makes a good beach detector

Multi-frequency technology

Salt water behaves like a conductor, which fools single-frequency machines into producing false signals. Multi-frequency detectors transmit several frequencies at once and process the returns together, which tends to give smoother, more stable performance on wet sand. Reviewers at Serious Detecting and Modern Metal Detectors both identify multi-frequency designs, especially the Equinox line, the Manticore and the XP Deus II, as the consensus picks for salt beaches.

Waterproof rating

Many hunters work the wet sand and shallow surf, so the whole detector and coil should tolerate immersion. Minelab lists the Equinox 900 as waterproof to 5 m and IP68. XP lists the Deus II as IP68 and submersible to 20 m, with a grey plug for land use and shallow water to 1 m and a red plug for full underwater use. Check what is actually waterproof on the machine you choose: on some detectors only the coil is submersible while the control box is splash-proof. Rinse everything in fresh water after each salt-water session.

Weight and balance

Beach sessions run for hours and sand is tiring to walk on. The Deus II is notably light, with a typical equipped weight starting around 750 g, according to the maker’s published figures and reviewers, though weights vary with coil and headphones. Minelab lists the Equinox 900 at about 1.27 kg. A lighter machine reduces fatigue, but balance and armrest comfort matter as much as the number.

Wireless audio

Cables get in the way near water. Both the Equinox 900 and the Deus II support wireless audio. Minelab supplies ML 85 low-latency wireless headphones with the 900, and XP uses a digital radio link between coil, remote and headphones on the Deus II. Waterproof headphones matter if you plan to wade.

Coils

Larger coils reach deeper and cover more ground, while smaller coils separate targets better in trashy areas such as popular tourist beaches with lots of bottle caps and foil. The Equinox 900 ships with an 11-inch and a 6-inch double-D coil, which gives you both options out of the box. Many hunters keep a small coil for crowded sand and a large coil for open stretches.

Detector-by-detector notes

Minelab Equinox 900

Serious Detecting’s 2026 beach guide names the Equinox 900 as the best beach detector for most hunters. The maker lists dedicated Beach modes alongside Park, Field and Gold, 119 target discrimination segments, and a rechargeable 5,100 mAh battery. It is a versatile choice because the same machine can be used on parks and fields as well as beaches. Reviewers repeatedly call the Equinox line the benchmark for saltwater performance.

XP Deus II

Serious Detecting rates the Deus II as best overall for beaches. It has a fully wireless design, a five-year warranty and a very light build. XP lists both fast multi-frequency programs and 49 single frequencies, which gives experienced users more control. The trade-off is a menu system that rewards study, so new users should plan time to learn it.

Equinox 700 and 800

These earlier or lower-tier Equinox models remain popular in roundups. Reviewers describe the 800 as a gold standard for salt-water performance, and the 700 as a more modest mid-range alternative. If you can find either at a mid-range tier, they offer most of the multi-frequency benefits of the line.

Minelab Vanquish 560 and Nokta Legend

For beginners, reviewers point to the Vanquish 560 as a budget option and the Nokta Legend as a good-value pick. Both are worth consideration if the premium machines are out of reach, but read the maker’s specifications on waterproofing before taking one near the surf, because water ratings vary between versions and between the control box and the coil.

Garrett AT Pro

The AT Pro is a popular all-terrain machine with a single frequency near 15 kHz, and reviewers state it is waterproof to 10 ft. Opinions on beach use differ. One guide lists ground noise as a problem on saltwater beaches and marks it as not saltwater ready, while another recommends it for wading and the surf line. It is a good fit for dry sand, freshwater beaches, lakes and general inland detecting.

Pulse induction machines

Pulse induction detectors ignore salt mineralization, which is why they are used by hunters targeting deeper items in the wash zone. The trade-off is that they offer little or no discrimination, so you dig everything metallic. They suit experienced hunters who accept the extra digging.

Practical beach tips

• Go at low tide, and after storms that strip sand to reveal older layers.
• Use a sand scoop rather than a spade, and fill holes you dig.
• Rinse the coil, shaft and control box with fresh water after every salt-water session.
• Learn local rules: many beaches, parks and protected areas restrict or prohibit detecting, and some require a permit. Do not dig in dunes or protected habitats.
• Watch tides and waves when wading, and never work alone in rough surf.
• If you find anything that looks like an artifact or an unexploded military item, stop and contact local authorities rather than handling it.

Budget tiers

• Budget: Entry detectors such as the Vanquish 560, or the Nokta Legend if it fits your needs. Good for learning on dry and damp sand.
• Mid-range: Equinox 700 or 800 style multi-frequency machines.
• Premium: Equinox 900, Deus II or Manticore for hunters working salt water often.

Pick X if you…

Alternatives

• Minelab Manticore: A flagship multi-frequency machine that reviewers praise for target ID on trashy beaches.
• Previous-generation Equinox models: A mid-range route into multi-frequency performance.
• A good pinpointer: A waterproof pinpointer speeds up recovery in loose sand and is often a better first accessory than a second coil.

Frequently Asked Questions

What type of metal detector works best on saltwater beaches?

Multi-frequency detectors are the consensus. They handle the conductivity of wet salt sand better than single-frequency machines. Pulse induction models also ignore salt but offer little discrimination.

Does the detector need to be fully waterproof?

If you plan to wade or hunt the surf, yes, at least the coil, and ideally the whole unit. Check the maker’s stated depth rating and which parts are submersible. Rinse with fresh water afterward.

Can I use a land detector on a beach?

You can use some on dry sand, but wet salt sand causes false signals and many land machines will chatter. Single-frequency units such as the AT Pro are better on dry sand and freshwater. Dedicated beach modes help considerably.

What size coil should I choose?

A medium coil of about 10 to 11 inches is a good balance of depth and target separation. A smaller coil helps on trashy beaches. A larger coil helps on open sand.

Is it legal to metal detect on beaches?

Rules vary by location. Many public beaches allow it, while parks, protected areas and some local jurisdictions restrict it or require permission. Always check with the local authority before you dig.

How do I look after a detector used in salt water?

Rinse the coil, shaft and any submersible parts in fresh water, dry the unit, and store it away from heat. Follow the maker’s manual about connectors and plugs. Keep batteries charged and sealed compartments clean.
