Vortex vs. Micro vs. Dredge: Which Big Foot Sluice Mat Do You Need?
Share
Five mat patterns, one decision — and picking the wrong one either lets fine gold slip through or leaves you scraping a stubborn mat clean at the end of a long day. If you've stood in front of the Big Foot Series lineup wondering what "Vortex" or "Cape-D" actually means for your gold, this guide breaks down all five patterns we build mats in, plus the two combo mats that pair two patterns on one sheet. By the end you'll know which mat fits your setup, whether that's panning paydirt in the backyard, working a creek with a sluice box, or running a dredge on heavy gravel.
What Actually Changes Between Mat Patterns
Every Big Foot mat starts from the same rubber matting, sized to fit sluice boxes from 6" up to 24" wide. Match your mat width to your box width — a 10" box needs a 10" mat, not a 12". What changes between patterns is the cell design molded into the surface: how deep the pockets run, how tightly they're spaced, and how much turbulence they create as water moves through.
Deeper, tighter cells hold onto fine gold longer but slow your feed rate. Wider, more open cells let you shovel through material fast but let go of the smallest flakes. Every pattern below sits at a different point on that trade-off, and none of them is the "best" one — just the right one for what's coming through your sluice.
Vortex — The All-Around Pick
The Vortex is our most popular mat and the one we'd point you to if you're not sure which pattern to buy. Its patented vortex cells create a small hydro-cyclone in each pocket, catching fine gold that flatter mats let wash past. It handles a normal mixed feed of gravel and sand without clogging, which is why it works equally well behind a shovel on a creek or feeding paydirt at home.
Available in the flagship 12x24 Vortex Dream Mat ($109.95) and the more compact 10x24 Vortex Dream Mat ($88.95).
Micro — Built for Ultra-Fine Gold and Finishing
When your gold runs mostly flour and fine flakes instead of pickers, Micro is the finishing mat. It's a low-flow pattern — you'll run material through slower than you would on a Vortex — but that trade-off buys you recovery on gold a faster mat would spit right out the tail end.
Prospectors working black sand concentrates, or running a second pass on material they've already panned once, reach for the 10x24 Micro Dream Mat ($85.95). It isn't the mat for shoveling raw creek gravel fast; it's the mat for not losing the gold that's already hard to see.
Mini — Faster Flow for Chunkier Material
Mini solves the opposite problem: too much material, not enough time. Its cells favor speed of flow over maximum fine-gold holding power, so it's the pick when you're feeding sandier or chunkier material and need to move volume without clogging your sluice.
It's also the pattern most often paired with Cape-D in a two-stage combo mat, covered below. On its own, it's the 10x24 Mini Dream Mat ($86.95).
Cape-D and the Combo Mats — Heavy Black Sand, Two Stages
Cape-D is built for heavy black sand and slower water, and we rarely sell it on its own — we pair it with a second pattern so one mat does two jobs. The 10x24 Cape-D/Mini Combo Mat ($87.95–$96.95) runs fast-flow Mini up top to handle volume, then Cape-D below to grab what settles out in heavy sand.
The 10x24 Micro/Cape-D Combo Mat ($87.95–$96.95) makes the same pairing but swaps in Micro for a finer first pass. If your gravel runs heavy on black sand, a combo mat saves you from running material through your sluice twice.
Dredge — Heavy Loads, Fast Clean-Up
Dredge is built for one job: keeping up with a suction dredge or highbanker pushing a heavy, continuous load. Its vortex cells are tuned to cut clean-up time so you're not standing over the sluice for twenty minutes at the end of a run, while still holding fine gold under that volume.
It's sold as the 10x24 Dredge Dream Mat ($94.95). One honest note: the clamp that holds it in your sluice is sold separately, since dredge and highbanker setups vary in what they need to stay put.

How to Choose
If you're still not sure, work backward from your setup instead of the mat name:
- Panning paydirt at home or working a creek with a small sluice — Vortex, our default recommendation.
- Chasing flour gold or finishing a concentrate you've already panned once — Micro.
- Shoveling sandy or chunky material and want speed — Mini.
- Heavy black sand and slow water — a combo mat (Cape-D/Mini or Micro/Cape-D) so you're not double-processing.
- Running a dredge or highbanker — Dredge, and budget for a clamp if you don't already have one.

FAQ
What sluice mat catches the finest gold?
Micro is built specifically for ultra-fine gold and flour. The Vortex's patented cells also hold fine gold well in a general-purpose mat, so it's a solid all-around choice if you don't want a dedicated finishing mat.
Does the Big Foot mat fit my sluice box?
Match width first. Our mats come in 6", 8", 10", and 12" widths up to 24", sized to fit the same-width sluice box — a 10" box needs a 10" mat.
Can I combine two mat patterns in one sluice?
Yes. The Cape-D/Mini and Micro/Cape-D combo mats already do this, pairing a fast-flow or fine-gold stage with heavy-sand Cape-D on a single mat, so you don't have to run material through your sluice twice.
Which mat should a beginner buy?
Vortex. It's our most popular pattern and the default recommendation any time you're not sure which one you need yet.
