For most beginners, the best first sluice is the one you can carry to legal water and set up correctly. A short backpack sluice suits small creeks and long walks. A full-size hand sluice moves more gravel where you can work closer to the car. A pump-fed concentrator is for cleaning up concentrates at home or camp, not for working a creek.
This list is desk research from maker product pages, catalogs, FAQs and instructions, checked October 5, 2026. Nobody at Backyard Prospectors has run these sluices, and no recovery rates are claimed. The rules section uses the federal and state agency pages linked below. Rules vary by state and land manager and change, so confirm them for the exact stream before you go.

Dream Mat 6x24 Trek: best backpack sluice
Prospector’s Dream calls the 6" x 24" Trek a backpack sluice designed to “fit into or attach to your pack.” The box is .05-inch-thick aluminum, 23.75 inches long, and comes with a 6" x 16" Dream Mat that the maker says cleans out into a gold pan or a 5-gallon bucket. The maker sells the Trek with several mats; the Amazon listing linked here is the Combo version.
The maker’s FAQ recommends its smaller Adventure sluice kit as the starting setup, and names the 6x24 Trek with a Combo Mat as the next choice if you want to move more material. The same FAQ says Micro and Combo mats work well with black beach sand.
Trade-offs: A 6-inch-wide box takes less gravel per shovel than a 10-inch one. Dream Mat’s FAQ says clay soil should go through a trommel, high banker or screen first so the gold is freed before it reaches the mat.
Keene A52: best full-size hand sluice
Keene describes the A52 as “the standard in the industry for decades.” Its 2022 catalog lists a 10-inch-wide, 4.5-inch-deep box of .063-inch aluminum with a removable 18-inch flare, a double-ribbed carpet under expanded zinc-plated steel, and a 25-inch riffle board with several riffle designs for high and low water flows. The catalog gives the length as 50 1/2 inches and the weight as 11 pounds; Keene’s store page lists 10" x 51" x 4.5".
It is also the pick to grow with. Keene says the A52 converts into a power sluice, a dredge or a double-length unit with parts sold separately. Dream Mat’s FAQ says any of its 10x36 mats fit the A52.
Trade-offs: It is the largest stream sluice here, so it suits sites with a short carry. An Amazon lookup did not find an exact A52 listing when checked, so the link is a search.
VEVOR 50" Folding Sluice Box: best long run that folds
VEVOR’s VV-JH-TJC50 is an aluminum alloy box that measures 50 inches long, 9 inches wide and 2.6 inches high, with 0.059-inch walls, a 13.7-inch flared opening and a listed weight of 10.14 pounds. VEVOR says the 18-gauge zinc-plated steel riffles are built in and the woven vinyl miner’s moss comes pre-installed, so setup is mostly fitting the flare.
Trade-offs: The length helps when you want more riffle area without a rigid 4-foot box, but it is still about 10 pounds to carry. VEVOR sells it in several bundle versions; the link goes to the 50-inch sluice listing.
Sluice Fox 12" Pocket Sluice: best for sampling and home cleanup
Sluice Fox says its pocket sluice is 12 inches long and meant for testing remote tributaries and hard-to-reach ground “where larger sluices are impractical,” and for “quick cleanups at home after a day on the river.” The metal version has expanded metal riffles over your choice of Miner’s Moss or V-Trap matting, and both mats are included.
Trade-offs: A 12-inch sluice is a sampling and cleanup tool, not a production sluice. Sluice Fox also sells a TPR version made of flexible rubberized plastic; the Amazon link here is the metal version.
Gold Cube 3 Stack Deluxe: best for concentrates
The Gold Cube is not a creek sluice. Gold Cube lists the 3 Stack Deluxe with one water tray, two vortex trays, an adjustable zinc-plated stand, and an 1100 GPH 12-volt pump with hose and fitting. The maker’s how-it-works page describes feeding it classified (1/8th) concentrates and says “90% (or more) gold will be caught in the first tray.” Gold Cube says you can add a tray later.
Trade-offs: It needs a pump, a water supply and pre-classified material. It makes most sense after you are already bringing home buckets of concentrates from a sluice.
How to choose a sluice box
- Start with the carry. If the walk is long, a short box like the Trek or the pocket sluice is easier to bring every time. Full-size boxes pay off where the carry is short.
- Match the width to the stream. In Washington, WDFW’s Gold and Fish rules cap a sluice’s widest point, including attachments, at 25% of the wetted width where you place it. Small creeks favor narrow boxes.
- Decide how you will classify. Keene’s high-banker instructions aim for material of about 1/2 inch “for best recovery,” and Washington allows only classified aggregate in a sluice within the wetted perimeter. Plan on a classifier screen either way.
- Think about cleanup. Every sluice ends with concentrates to pan. Dream Mat suggests running concentrates over a clean-up sluice, which is the job the pocket sluice and Gold Cube do best.
- Buy for the gear you will add. The A52 converts to a power sluice or dredge with Keene parts; the Gold Cube takes extra trays.
How to set up and clean out a sluice
- Find moving water over a firm base. Washington’s rules limit sluicing to areas within the wetted perimeter “composed primarily of boulders and bedrock,” and other states have their own limits.
- Set the angle, then watch it. Keene’s instructions say to start at about 10 degrees and adjust toward level “without allowing the gravel to build up over the riffles,” because “if the sluice box is tilted too much the material will flow over the riffle section.” Dream Mat gives 7 to 12 degrees for its mats and says to watch for material “dancing” in the cells: it should stay in the cells without blowing clear.
- Feed classified material slowly. A steady feed lets the riffles keep up.
- Clean out over a tub. Keene’s cleanup steps are to place a pan or bucket at the end, lift out the riffle tray, lift the screen, roll the carpet into the bucket, and wash out the gravel left in the box, which Keene says “may be where the majority of all values have collected.” Then pan the concentrates.
Sluicing rules vary by state and land manager
The federal baseline is permissive, but states and individual units add limits. These examples come straight from the agencies; none of them guarantees a particular stream is open.
| Agency | What it says about non-motorized sluices |
|---|---|
| BLM, 43 CFR 3809.5 | Casual use “generally includes … non-motorized sluicing” |
| BLM Nevada (undated brochure) | Hand tools and pans are fine; “sluicing, dredging and commercial mining require permits” |
| Forest Service, 36 CFR 228.4 | No notice of intent for “non-motorized hand sluicing” |
| White Mountain NF (NH) | Free panning permit; sluice boxes are prohibited |
| Washington | Agency documents differ (see below); ask WDFW |
| Oregon DEQ | No application for in-water non-motorized equipment; carry a permit copy |
| Idaho IDWR | Letter Permit for non-powered sluices moving over 1/4 cubic yard per hour |
Washington’s two agency documents describe sluice rules differently. The Washington Department of Fish and Wildlife (WDFW) says its 2021 Gold and Fish pamphlet serves as the Hydraulic Project Approval (HPA) for the activities it describes, and the pamphlet allows non-motorized sluices with riffle areas totaling 3 square feet or less, under width and site limits. The state geology division’s older panning sheet (revised 2010) says no formal HPA is needed for a “non-motorized, small sluice box,” but “You must have a formal HPA for sluicing and dredging,” without saying where one ends and the other begins. WDFW administers HPAs, so confirm with WDFW before you sluice in Washington.
Mining claims are a separate question from these rules. BLM’s 2026 claims packet for Montana and the Dakotas says that to prospect on an existing unpatented claim, “you must have permission from the current claimant.” For the wider access picture, start with the public land access checks .
Where a sluice fits with other gear
A sluice concentrates gravel; a pan finishes the job. If you still need the pan, the Garrett Gold Pan Kit review covers a kit that includes pans, a classifier and a recovery bottle. If you are weighing a pump-driven setup instead, read metal detecting vs gold dredging and the state rules for gold dredging first.
FAQ
What angle should a sluice box be set at?
There is no single number. Dream Mat gives 7 to 12 degrees for its mats, and Keene’s instructions say to start at about 10 degrees, then get as close to level as possible without gravel building up over the riffles.
Do I need a permit to use a sluice box?
It depends on the state and the land manager. Federal rules treat non-motorized sluicing as casual use on BLM land and need no notice on National Forest land, but some states and individual forests restrict or prohibit sluices, so check the agency for the exact stream.
Should I classify material before sluicing?
Usually yes. Keene’s instructions aim for material of about 1/2 inch, and Washington’s Gold and Fish rules allow only classified aggregate in a sluice within the wetted perimeter.
