Where to detect
Metal Detecting on the Beach: Zones, Tides and the Right Scoop
Quick answer
Work a beach in zones: the dry towel line for recently dropped jewellery, the wet sand and the low tide line for older heavy targets that have worked downslope, and the cuts and scours after a storm for anything that has been uncovered. Use a scoop rather than a digger, and hunt the falling tide.
A beach is not one site, it is three or four sites layered on top of each other, and they produce different things. The dry sand above the towel line holds what people dropped this season, mostly light and shallow. The wet sand and the slope below it hold heavier targets that have migrated downwards over years. The cuts and scours that appear after rough weather expose whatever the sand had been protecting, which is why experienced beach hunters watch the surf forecast rather than the calendar.
Beaches also carry the winter for a great many detectorists, because sand does not freeze solid and does not hold a plug scar the way turf does. What it does have is salt, which is a genuine technical problem covered in the saltwater guide, and a legal position that is often more complicated than people assume.
Top pick
CKG 304 Stainless Sand Scoop
A 304 stainless scoop sifts sand instead of fighting it, at about half the price of the flagship scoops, which makes it the sensible first one.

How should you divide up a beach?
Hunt the zones deliberately rather than wandering. Each one answers a different question, and knowing which you are working tells you what a good signal should sound like.
The dry towel line holds recent light losses, the wet sand and low tide line hold older heavy targets that have worked downslope, and post storm cuts expose material that has been buried for years.
| Zone | Typical finds | Conditions | Tool and approach |
|---|---|---|---|
| Dry sand, towel line | Recent coins, light jewellery, sunglasses, keys | Shallow, loose, easy digging | Long handled dry scoop, quick grid over sunbathing areas |
| Dry sand, access paths | Dropped change and keys in concentration | Compacted, high traffic | Slow passes along the natural walking lines |
| Damp sand above the tide line | Mixed ages, heavier items starting to appear | Firmer, holds a hole briefly | Stainless or titanium scoop, work the contour |
| Wet sand below the tide line | Older coins, rings, heavy lead and iron | Salt response, hole fills with water | Scoop with drainage, multi-frequency or beach mode |
| The slope and low tide line | The heaviest and often the oldest targets | Only accessible on a low tide | Plan the session around the tide table |
| Storm cuts and scours | Whatever the sand had been covering | Temporary, and worth dropping everything for | Work the exposed face and the base of the cut |
| Shallow water and surf | Rings lost while swimming, heavy modern loss | Moving water, cold, poor footing | Long handled water scoop and a waterproof machine |
Which zones are legally accessible varies enormously, and dry sand and foreshore frequently have different owners. Check locally before you plan a session around any of them.
Why does the tide decide the session?
Because the productive ground is only available for part of the cycle. The slope and low tide line are where heavy targets accumulate, and you can only work them around low water. The practical routine is to arrive as the tide is falling, follow it down, work the newly exposed sand, and leave yourself a clear margin before it turns. A rising tide on a beach with cliffs or groynes behind you is how people get cut off, which is a safety point rather than a hunting one.
Rough weather matters more than the calendar. Storms strip sand and open cuts that expose layers which have been sealed for years, and those cuts are temporary. Detectorists who do well on beaches are the ones who go immediately after the weather rather than at a convenient time. Check the forecast and the tide table together, and plan the grid before you arrive using the search grid planner.
What gear does a beach actually demand?
A scoop, first and above everything. A digger in sand is slow and futile: you need something that lifts a volume of sand and lets it drain while the target stays behind. The CKG 304 Stainless Sand Scoop is the sensible entry point, the RTG 33 inch Beach Sand Scoop is a long handled dry sand scoop from a maker that has specialised in them for years, and the RTG Pro Aluminum 47 inch Mini Water Scoop is the long aluminium version for wading at arm length. The GADFISH Stainless Sand Scoop is the cheapest way to find out whether beach hunting suits you at all.
After that, drainage. A Mesh Bottom Beach Finds Pouch with pinpointer holster has a mesh bottom so sand and water fall through instead of turning the pouch into a bag of wet grit, and the Waterproof Mesh Waist Pouch does the same job for less. A carbon handle such as the CKG Carbon Fiber Sand Scoop Handle is the upgrade that makes a heavy scoop usable for a full tide. For salt water specifically, the titanium argument in the saltwater guide is worth reading before you spend.
Which machine settings suit sand?
Use the beach mode your machine publishes, because it exists for the salt problem rather than for marketing. Dry sand is usually undemanding and most machines handle it in a general purpose mode. Wet salt sand is the hard case, since salt water is conductive and a single frequency machine struggles to separate the salt response from a target response. Simultaneous multi-frequency machines such as the Minelab Equinox 900 and the Minelab Vanquish 540 Pro-Pack were built for exactly that, and Garrett publishes a dedicated Multi-Salt mode on the Garrett ACE Apex and the Garrett Vortex VX7.
Black sand is the other complication. Heavy mineral concentrations show up as dark streaks and produce the same chatter as mineralised inland soil, which is a ground balance question covered in the ground balance guide. Expect to run lower sensitivity across those streaks rather than fighting them, and expect your depth to drop while you are on them, much as the depth chart describes for mineralised ground generally.
How do you work a beach efficiently?
In lanes, parallel to the water, overlapping each sweep. Beaches look featureless and it is remarkably easy to cover the same strip three times and miss the one beside it, which is why a grid discipline pays for itself. Work the contour rather than up and down the slope, because targets sort themselves by weight along contours rather than across them.
Keep the coil flat on the sand and move slowly. The temptation on an open beach is to cover ground quickly because there is so much of it, and that is precisely how the deep heavy targets get missed. If you want an honest figure for how long a stretch takes, the coil coverage and sweep time calculator converts coil width and sweep speed into hours, and a large coil such as the Minelab EQX 15 Coil (15 inch) genuinely helps here, for the reasons the coil size chart sets out.

Frequently asked questions
What is the best time to detect a beach?
Follow a falling tide down and work the newly exposed sand, then leave a clear margin before it turns. Immediately after rough weather is better still, because storms strip sand and open cuts that expose material buried for years. Those cuts are temporary, so the people who do well on beaches go when the weather says to rather than when the diary allows.
Do I need a special detector for the beach?
For dry sand, no. For wet salt sand, it matters a great deal, because salt water is conductive and single frequency machines struggle to separate the salt response from a target. Simultaneous multi-frequency machines and dedicated salt modes exist for that problem. If your machine has a beach mode, use it, and expect to lose some depth regardless.
Why do I need a scoop instead of a digger?
Because sand collapses. A blade cuts nothing useful and you end up scraping a widening crater while the target sinks further into the spoil. A scoop lifts a volume of sand and lets it drain through the holes, leaving the target in the basket. In wet sand and surf it is the only practical tool, and on dry sand a long handled scoop saves your back.
Is the dry sand or the wet sand better?
They answer different questions. Dry sand around the towel line holds recent, light, shallow losses, so it is quick and productive for modern jewellery. Wet sand and the low tide line hold older, heavier targets that have worked downslope over years, so the finds tend to be better but the ground is harder to work and the salt makes the machine work harder too.
Do I need permission to detect on a beach?
Usually yes, and often from more than one body. The dry sand above the high water mark is frequently controlled separately from the foreshore below it, which may belong to a coastal or crown authority. Many beaches also carry seasonal restrictions around dunes and nesting areas. Check who controls each zone locally before you plan a session, because the answer varies enormously.
