Gold Sluice Boxes for Sale: Backpack to Production Size
A sluice box does the work of dozens of gold pans. You set it in moving water, shovel classified material into the head, and let the current carry the light gravel away while gold, which is roughly 19 times heavier than water, drops out and stays in the matting. Our gold sluice boxes run from a 4x16 that rides in a daypack to a 12x47 that eats a full shovel at a time, with dredge editions and clean-up sluices for the jobs a standard box does not cover. Sizes are width by length in inches, so a 10x35 is a 10-inch wide channel that is 35 inches long.
How a Sluice Box Works
Water flowing over the matting creates small eddies behind every ridge in the mat. Heavy particles fall into those low-pressure pockets and stay there, while sand and gravel keep moving. Traditional sluices used tall metal riffles to create those eddies. Prospectors Dream sluices use Dream Mat, a molded matting designed to trap fine and flour gold without riffles, which makes the box lighter, simpler to set up and faster to clean out. The job of the operator is simple: keep the water flow steady, feed material at a pace the box can clear, and never let the matting pack solid with sand. For the full walkthrough, from reading the water to choosing a highbanker, see our Sluice Box Guide.
What Size Sluice Box Should I Buy?
- 4x16 Adventure sluices: backpack size for sampling new creeks, hiking into remote ground, and testing before you commit to bigger gear.
- 6x24 Trek and 6-inch folding sluices: the all-round size for most hobby prospectors. Light enough to carry, big enough to run a real day of material.
- 8-inch sluices (8x35, 8x38, 8x47): the step up for claim work and club digs where you move volume every trip.
- 10 and 12-inch sluices (10x35 up to 12x47): production boxes for serious material. Wider channels need more water, so match them to a creek with steady flow or a pump-fed setup.
If you are buying your first sluice, a 6x24 is the size we recommend most. If you already sample with a pan and know your creek carries gold, go 8 or 10 inches wide.
Micro, Mini and Combo Dream Mat
Most sluices here come with a choice of matting. Micro mat is built for fine and flour gold, the size most creeks actually carry. Mini mat is tuned for coarser gold and pickers. Combo sluices run both in one box so you catch the full range without swapping mats. If you are unsure what your ground holds, combo is the safe choice. Classifying your material first with a classifier makes any mat recover more, because gold settles far better when everything in the flow is a similar size.
How to Set Up a Sluice Box
Place the box in a stretch of creek with steady current, head facing upstream, and bed it on rocks so it does not rock or shift. A good starting angle is about one inch of drop per foot of sluice length. Then adjust by watching the box: if material piles up and the matting fills with sand, add slope or water; if gravel races through and the mat stays bare, flatten the angle or slow the flow. Water should cover the matting and move material steadily down the box without boiling over the sides. Feed material in small, consistent shovelfuls rather than big dumps.
Dredge Editions and Clean-Up Sluices
Dredge edition sluices mount behind a mini or micro dredge, so you can pull material from the stream bottom and run it straight through the box. The Boss clean-up sluice kits solve the other end of the day: they run in a tub of recirculated water, so you can run your concentrate down at camp or at home instead of panning every cup by hand. For the final fine gold, finish in a gold pan or a concentrator like a Blue Bowl. Our guide to recovering flour gold walks through that last step.
Sluice Box vs Highbanker vs Power Sluice
A sluice box relies on the creek for its water, so it has to sit in the stream. A power sluice adds a pump and header box that feed water into the sluice, so you can set it on the bank and control the flow. A highbanker takes that further with a hopper and grizzly on top, so you can shovel unclassified material straight in and work gravel benches away from the water's edge. Start with a sluice; move to a power sluice or highbanker when your best gold is up on the bank instead of in the channel.
How Often to Clean Out a Sluice
Clean out whenever the matting starts to pack with black sand, and at the end of every session. Lift the mat over a bucket or tub, rinse it thoroughly, and pan or clean-up-sluice the concentrate. Dream Mat rinses clean far faster than riffle-and-carpet setups, which is a big part of why it has become the standard. Never leave concentrate in the box overnight: a rain-swollen creek will wash it out for you.
Is It Legal to Use a Sluice Box?
In most of the US, a hand sluice is allowed on public land that is open to recreational prospecting and on private land or claims where you have permission. Rules vary by state, by waterway and by season, and motorized equipment like pumps and dredges often needs a permit. Check your state and the land manager (BLM, Forest Service or state parks) before you set up. Our laws and code of ethics guide is a good place to start.
How to Choose Your First Sluice Box
- Where you will run it: hike-in creeks favor a 4x16 or 6x24; drive-up claims can handle 8 inches and wider.
- What gold your ground carries: fine gold country calls for micro or combo mat.
- How you will finish: pair the sluice with a classifier up front and a pan or clean-up sluice at the end.
