Best Sluice Box for Gold: Compared by Type & Recovery

Best sluice box for recreational gold mining: the short answer

For most hobby prospectors, the best sluice box for recreational gold mining is a 10-inch-wide aluminum hand sluice about 4 to 5 feet long, with expanded metal riffles over unbacked loop matting. Expanded metal riffles over loop matting are the layout that the Yukon pilot tests and the BGS field trials describe as a good gold trap, and it costs well under US$200 from a major US maker (Keene’s A52 hand sluice listed at US$174.95 on its 9 February 2026 price list). Pay more only when your site needs it: a folding box for long hikes, a highbanker for ground away from the water, or a powered sluice where the rules allow motors.

This guide compares sluice boxes by type rather than by star rating, because the type decides how much gravel you can move, how fine a gold you keep and where you are allowed to run it. You will find a comparison table, ranked picks by use case with honest drawbacks, dated maker prices, set-up numbers from geological surveys, a calculator for slope, water and value, and the permit rules that apply in several US states and in Scotland.

A few terms first. A sluice box is a sloped trough that water runs through; heavy gold drops behind small bars called riffles while lighter sand washes out the end. Placer gold is loose gold in river sand and gravel, as opposed to lode gold still locked in rock. Concentrate is the heavy black sand and gold left in the box after a run. Classifying means screening gravel to a smaller size before it goes into the box.

How we chose and compared the sluice types

We compared sluice designs against what public research says matters for recovery, not against marketing claims. The main references are the British Geological Survey handbook on sluice box design (BGS, Good practice in the design and use of large sluice boxes, CR/02/029N), the Washington State Department of Natural Resources guide to placer gold mining, and the Yukon Geological Survey pilot-scale riffle tests. Prices come from the dated retail price lists of Keene Engineering, a California maker that publishes its full list, so readers can see real numbers with a date attached.

Each type was judged on five points:

• Fine gold recovery: does the riffle and mat layout hold gold finer than about 0.5 mm, where most recreational losses happen?
• Throughput: how much gravel one person can push through in a day.
• Portability: weight and whether it folds for a hike.
• Water needs: whether it needs a flowing stream or can run from a pump and tub.
• Permit fit: whether the type is a non-motorized hand tool or motorized equipment, since many rules treat the two very differently.

We do not score individual brands on recovery percentages, because no independent body tests retail sluices against each other. Where a model is named, it is an example of the type with a published maker price or specification, not a paid placement.

Best sluice box by use case

These picks are ranked for a typical weekend prospector who works a stream on foot and wants to keep fine gold. If your site or rules differ, jump to the pick that matches them.

1. Standard aluminum hand sluice: best overall for recreational use

Best for: first-time and regular stream sluicing where a creek has steady flow a few inches deep.

A fixed aluminum hand sluice about 10 inches wide and roughly 4 feet long is the type most guides start beginners on. Keene’s A52 is one example, listed at US$174.95 in February 2026, up from US$169.96 in May 2025. The width matters: the Yukon pilot tests used a sluice run just 6 inches wide, and the BGS handbook stresses that a box that is too wide for the flow spreads water thin and lets gold settle unevenly.

Pros: low cost, no moving parts, quick clean-up, works with replaceable expanded metal riffles and mats. Cons: needs a natural current of the right speed; you shovel every load by hand.

2. Folding backpack sluice: best portable sluice box

Best for: creeks you can only reach on a long walk.

Folding boxes give up some rigidity and riffle length to pack small. Keene describes its A52F folding model as having a 40-inch recovery riffle area, 63 inches overall and a weight of 9 pounds (Keene Engineering, A52F product note). That is a useful benchmark when you compare other folding sluices: check the length of the riffle section itself, not only the overall length with the flare.

Pros: light, straps to a pack, often uses rubber riffles that clean fast. Cons: hinges and thin sides can flex if the box is not seated well; less capacity than a full-size box.

3. Multi-stage sluice with classifier: best sluice box for fine gold

Best for: rivers and beaches where most gold is flour-sized or fine flakes.

The BGS handbook found that recovery in a typical sluice drops off fast for gold finer than about 100 microns (0.1 mm). Two things help: screening the feed so particles are of similar size, and running a slower, wider or longer section with mats for the fine fraction. A multi-stage box such as Keene’s A52S (US$495.95 in February 2026) comes with options such as a classifier screen system and add-on riffle screens, and can be converted into a pumped unit later.

Pros: better control of flow for fine gold, modular. Cons: more parts, heavier, and the extra set-up only pays off if your gravel really carries fine gold.

4. Mini sluice: best for sampling a new creek

Best for: testing several spots in a day before you commit to one.

A mini sluice is cheap and light (Keene’s A51 Mini Super Sluice listed at US$139.95 in February 2026), so it is handy for checking which bars carry colour. The trade-off is a short riffle area. The Washington guide notes that with a short sluice box it is time to clean up as soon as black sand starts going over the second and third riffles, so you will stop to clean more often.

Pros: fits in a day pack, ideal for sampling. Cons: low capacity; fills and needs cleaning quickly.

5. Highbanker: best for gravel away from the water

Best for: old benches and bars above the stream, or sites without a usable current.

A highbanker is a sluice on a stand fed by a pump, with a hopper on top. Washington’s rules define it as a sluice box, hopper and water supply, with the gravel brought to it by means other than suction dredging (Washington Department of Fish and Wildlife, Gold and Fish rules, 2021). Keene’s double-pump highbanker listed at US$1,349.95 in February 2026.

Pros: lets you work ground the creek cannot reach; can recirculate water from a pond or tub. Cons: pump, fuel and hoses add weight; motorized pumps bring permit conditions in many states.

6. Power sluice: best for volume where motors are allowed

Best for: claim owners who process more gravel than a shovel crew can feed.

A power sluice pairs a sluice with an engine-driven pump, and many can take a dredge hose. Keene’s 4 hp power sluice listed at US$3,039.95 in February 2026. This is where recreational sluicing starts to look like small-scale mining, and where the strictest water rules apply.

Pros: much higher throughput. Cons: highest cost, heaviest, and banned or tightly permitted on many waters.

Sluice box prices from a US maker

No government or trade body tracks retail sluice prices, so the most reliable dated figures are a maker’s own list. Keene publishes its master price list, and comparing the May 2025 and February 2026 lists shows prices rising by roughly 3% to 5% for the sluices shown below. The maker attributes changing prices to the cost of raw materials. Expect similar movement from other aluminum-box makers, and budget for extras: a replacement expanded metal riffle sheet listed at US$35.00, and a rubber mat for the folding sluice at US$47.95 (February 2026).

A practical starter kit for a stream is a hand sluice, a classifier screen, two buckets, a shovel and a gold pan for the final clean-up. That keeps the total close to the price of the sluice itself plus a few small tools. Spend on a highbanker or power sluice only after sampling shows the ground is worth it and you have confirmed that motorized equipment is allowed at the site.

How to set up a sluice box for fine gold

A well-chosen box loses gold if it is set up badly. The public research gives clear starting points.

Infographic

Setting up a stream sluice in 5 steps

1. 1ClassifyScreen out cobbles; about 25 mm suits most alluvial gravel.
2. 2Seat the boxBed it level side to side in a steady current.
3. 3Set the slopeStart at up to about 1 inch of drop per foot.
4. 4Feed steadilyKeep the slurry mostly water and about 20 to 30 mm deep.
5. 5Clean up earlyClean when black sand passes the first riffles.

Slope

The Washington DNR guide gives common grades for sluice boxes of up to about 1 inch of drop per foot of box (Washington DNR, Placer gold mining in Washington). It adds that the right grade depends on the gravel, the gold, the riffles and the water available. For large commercial boxes, the BGS handbook says most are set at around 10 to 15 degrees, with the exact slope tuned together with width and feed rate. For a small hand sluice in a creek, start shallow and steepen only if gravel starts packing behind the riffles.

Water

Water does the work. The Washington guide says 7 to 13 times as much water as gravel is generally needed to move loose sand and gravel through a sluice box. The BGS handbook puts it the other way round: water makes up about 85% to 95% of the feed volume, so the mix should be about 5% to 15% ore by volume, and the slurry stream should be about 20 to 30 mm (3/4 to 1 1/4 inches) deep. Feed the box steadily; surges push concentrate out of the riffles.

Riffles and mats

A Yukon Geological Survey report describes a pilot-scale test rig at Yukon College in Whitehorse that cycled placer gravel under half an inch through an 8-foot by 6-inch sluice run to test riffle types, spacings, feed rates, water rates and slopes, then salted the feed with irradiated gold to check results (Yukon Geological Survey, An analysis of sluicebox riffle performance). The BGS handbook, which draws on that Clarkson research, describes expanded metal riffles over loop vinyl matting (sold under names such as Nomad) as a good trapping mechanism, and warns that carpet-type mats wear quickly and lose their ability to hold coarser gold.

Classifying the feed

Screening out cobbles keeps the flow even and stops big rocks from scouring gold out of the riffles. BGS suggests a screen around 25 mm (1 inch) for alluvial gravel, and finer where the gold is fine. Classifying also brings particle sizes closer together, which the handbook notes makes density separation work better.

Clean-up timing

Clean up before the riffles pack. Gold cannot settle into a riffle that is already full of black sand. In the BGS field trials, most of the recovered gold was found in the first two or three metres of the box, so watch the top section closely and clean when it starts to fill.

What size gold is in your gravel

Knowing the size of your gold tells you which sluice type to buy. The BGS team sieved gold from a test concentrate at Mahdia, Guyana, and found most of it by weight between 0.125 mm and 2 mm, with very little finer than 0.063 mm. In that sample the box should get very good recovery, because little of the gold was in the hardest-to-catch fine sizes. Your creek may be different: pan a few samples, dry the gold and look at it under a hand lens before you choose between a standard box and a multi-stage fine gold set-up.

Gold is far denser than quartz sand, which is why it sinks behind riffles while sand washes past. Very thin flakes are the exception: their shape slows their settling, so they need slower flow and good matting.

Hand sluice vs highbanker vs power sluice

The jump from hand tools to motorized gear changes both output and rules. Oregon’s Department of Environmental Quality, in its fact sheet for the 700-PM placer mining permit, estimates that a typical non-motorized hand sluice processes about 5 cubic yards of material a year, and lists maker specifications for motorized suction dredges from 1.4 to 20 cubic yards an hour depending on size and brand (Oregon DEQ, 700-PM permit renewal fact sheet). That gap is the reason regulators treat the two classes so differently.

The Washington guide gives a sense of hand-shovel output for a larger box: two people shovelling by hand can handle 10 to 15 cubic yards of loose sand and gravel in a 10-hour shift. Most recreational sessions move far less, because time goes into sampling, set-up and clean-up.

The Alaska Placer Mining 101 Guidebook (March 2026), produced with the Bureau of Land Management, says sluice boxes remain by far the most commonly used gold recovery equipment in Alaska, and describes them as efficient, relatively inexpensive and low maintenance because they have no moving parts (BLM Alaska, Placer Mining 101 Guidebook). The same guidebook sets out the design, permitting and reclamation steps for anyone scaling up to commercial placer work.

Where you can legally run a sluice box

The right box is useless at a site where you are not allowed to use it. Rules depend on who owns the land, who owns the minerals and which agency protects the water.

United States

• Washington: the Gold and Fish pamphlet acts as the permit (Hydraulic Project Approval) for the activities it covers. Pans, mini rocker boxes, non-motorized mini highbankers and sluices with riffle areas totalling three square feet or less have the widest set of allowed locations. If you use a sluice with more than three square feet of riffle area within the wetted perimeter or frequent scour zone, you must classify the gravel at the dig site before processing. The rules do not replace landowner permission.
• Oregon: under the 700-PM general permit, motorized suction dredges must register with DEQ, while other in-water non-motorized equipment such as a hand sluice does not need to register but must follow the permit terms.
• California: rules on panning, sluicing and motorized equipment are set out in our guide to gold panning laws in California, and claim rules in our California gold mining claims guide.
• Mining claims: on federal land a valid claim belongs to its owner, so sluicing on someone else’s claim without permission takes their minerals. Check BLM records before you dig.

Scotland and gold panning locations in the UK

In Scotland, naturally occurring gold belongs to the Crown under the Mines Royal Acts except where rights were granted away, as in Sutherland and parts of Argyll. Crown Estate Scotland’s policy is that it does not grant permission to remove gold through recreational panning, and it notes that panning is also subject to environmental regulation by SEPA and may need a permit (Crown Estate Scotland, statement on recreational gold panning, 2026). Ownership of the gold is separate from ownership of the land, so landowner access does not settle the question.

The best-known place to try gold panning in the UK is the Lowther Hills around Wanlockhead and Leadhills in southern Scotland. The Museum of Lead Mining in Wanlockhead runs taster sessions in panning tanks and longer courses with a local instructor, and says some visitors have gone on to pan in local burns after buying equipment and a licence from the museum (Museum of Lead Mining, gold panning in Scotland). Ask the museum what that licence covers before you set up a sluice in a burn. In England and Wales, get the landowner’s written permission and check whether the river is a protected site before you dig.

Cleaning up your concentrate without mercury

A sluice does not give you clean gold; it gives you a few cups of heavy black sand with gold in it. Pan the concentrate down, then pick or snuff out the gold, or use a small concentrating table or wheel. Do not use mercury. The US Environmental Protection Agency lists panning and sluicing among the gravity concentration methods that can eliminate or greatly reduce the need for mercury, relying on the high density of gold (US EPA, artisanal and small-scale gold mining without mercury). Washington’s guide also points out a useful check: if you recovered black sand, you should also have recovered any gold that was present, so black sand in your pan is a sign the box is working.

Finding ground worth sluicing

The best equipment only recovers gold that is in the gravel you feed it. Sampling with a pan and a mini sluice is the cheapest way to compare bars on one creek. For larger areas, claim owners and small mining companies often start with geological maps, old mining records and satellite imagery. Regional guides such as our page on gold prospecting in Colorado and the US mining map of active mines by state show where placer districts sit.

Farmonaut’s satellite-based mineral detection maps alteration and structure across a claim or licence area from a boundary file, so a team can choose which drainages to sample first. It points to targets for field checking; it does not replace sampling.

Frequently asked questions

What is the best sluice box for recreational gold mining?

For most people it is a standard aluminum hand sluice about 10 inches wide and 4 to 5 feet long with expanded metal riffles over loop matting. It is cheap, simple and suits most streams. Choose a folding box for long hikes and a multi-stage box if your gold is very fine.

What is the best sluice box for fine gold?

A box that lets you slow and spread the flow over good matting, ideally with a classifier screen on the feed. BGS research found recovery falls off fast for gold finer than about 0.1 mm, so screening the feed and cleaning up often matter as much as the box.

What is the best portable sluice box?

A folding aluminum sluice. As a benchmark, Keene’s A52F folds to a pack-sized bundle, weighs 9 pounds and has a 40-inch riffle area. Compare riffle length, not just overall length, when you shop.

What is the best sluice box for beginners?

A fixed hand sluice with removable riffles, plus a gold pan for the clean-up. It teaches you how slope and water depth change what the riffles hold, and costs under US$200 from major makers (Keene list prices, February 2026).

What angle should a sluice box be set at?

For a small stream sluice, start at up to about 1 inch of drop per foot, the common range in the Washington DNR guide, and adjust until gravel moves but black sand stays behind the top riffles. Large commercial boxes run steeper, around 10 to 15 degrees in the BGS handbook.

How much water does a sluice box need?

Far more than gravel. The Washington guide gives 7 to 13 times as much water as gravel, and BGS says water is about 85% to 95% of the feed volume. Aim for a stream about 20 to 30 mm deep over the riffles.

How often should I clean out my sluice box?

Whenever black sand starts building past the first few riffles. The Washington guide uses black sand reaching the second and third riffles of a short box as the signal to clean up.

How much does a good sluice box cost?

Keene’s February 2026 list shows a mini sluice at US$139.95, a standard hand sluice at US$174.95, a super sluice at US$495.95, a double-pump highbanker at US$1,349.95 and a 4 hp power sluice at US$3,039.95. Prices rose about 3% to 5% from the May 2025 list.

Do I need a permit to use a sluice box?

It depends on the place. In Washington, small non-motorized sluices are covered by the Gold and Fish rules with location limits; in Oregon, non-motorized in-water equipment does not register under the 700-PM permit but must follow its terms. You always need permission from whoever owns the land and the mineral rights.

Where are the best gold panning locations in the UK?

The Lowther Hills around Wanlockhead and Leadhills in southern Scotland are the best known, and the Museum of Lead Mining there runs courses. Crown Estate Scotland does not grant permission to remove gold through recreational panning, so check the rules before you go.
