Gold Classifiers & Sifters

Gold Classifiers & Sifters for Every Mesh Size

A gold classifier is the most underrated tool in prospecting. Gold stratifies cleanly when everything in the pan is the same size; throw cobbles and flour into the same swirl and the fine gold rides out on the turbulence. Run material through a classifier first and the same pan recovers noticeably more gold in less time. Our gold classifiers and sifters run from 1/2-inch bucket screens for breaking down raw bank material to 1/100 mesh for the flour-gold range, in single screens, stackable sets, and full-width hand sifters, all field-tested by the prospectors on staff.

Gold Classifier Screen Sizes Explained

Classifier mesh is named by holes per linear inch: a 1/2" screen passes material under half an inch, a #8 (1/8") screen passes material under an eighth, and a #100 passes only what fits through a hundredth. The working rule: classify to roughly the size of the gold you expect, one or two steps down from your raw material. For most creek and bank ground, 1/2" knocks out the cobbles, 1/8" preps material for panning, and #20 through #100 walk concentrate down for cleanup. Fine gold country (beach sands, flood layers, clay seams) earns the #30 to #100 range, where a classifier saves gold a bare pan loses. If you only buy one screen, buy a 1/2"; if you buy a set, get a spread like 1/2", 1/8", and 1/30.

5-Gallon Bucket Classifiers

The bucket classifier is the standard field setup: the screen nests on the rim of any 5-gallon bucket, you shovel pay dirt on top, shake, and the bucket catches classified material ready for the pan. The Garrett 14" sifter and Minelab PRO-GOLD 1/2" hex classifier are the proven names here, and TerraX builds a complete bucket kit with the classifier, pan, and snifter bottle included. A bucket classifier also doubles as your transport: classify at the dig, haul home only material worth working, and leave the cobbles where they came from.

Stackable Gold Classifier Sets

A gold classifier set stacks multiple mesh sizes into one column, so a single shake sorts material into ready-to-work fractions. The Camel Mining 5-piece set and our 8.5-inch 6-piece set cover the panning range, TerraX 6-inch screens (10 to 60 mesh) stack for sampling and concentrate work, and Gold Cube Golden Rule 4-screen and 16-screen packs walk concentrate down for cleanup. For volume work, the Raytech 16-inch set of 5 nests from coarse to fine. Sets cost less per screen than buying individually, and the graduated sizing is what makes cleanup systematic instead of guesswork: each fraction pans at its own speed, and the gold in each is the same size as everything around it.

16-Inch Hand Sifters & Large Screens

When you're processing volume (testing a bench, feeding a highbanker, working a club dig), a full-width hand sifter moves more material per shake than any bucket-top screen. Raytech's 16-inch classifiers come in sizes from 1" down to 1/4" and nest as a set, and the XP 15" classifiers (10mm and 5mm) lock onto XP's pan system for a clean two-person workflow: one digs and classifies, one pans. Big screens earn their pack weight anywhere the dirt is faster than the panning.

Fine Mesh Classifiers for Concentrate & Cleanup

Below #20 mesh, a classifier stops being a digging tool and becomes a cleanup tool. Screening concentrate to a uniform fine fraction is what lets a spiral wheel, Blue Bowl, or Gold Cube run at full recovery. Every one of those machines specifies a maximum feed size, and the screens in this collection are how you hit it. Blue Bowl #100 screens and Gold Cube's Golden Rule screens exist for exactly this job. If your black sand cleanup loses flour gold, the fix is almost always classification, not a new machine.

How to Choose the Right Classifier

Match the screen to the job, not the other way around:

• Digging & panning: A 1/2" bucket classifier plus a 1/8" screen covers most creek work. Add a pan and you have the complete starter loop.
• Sampling & fine gold: A stackable set with a spread of mesh sizes shows you what sizes your ground actually carries before you commit to bigger gear.
• Volume processing: A 16-inch hand sifter feeds a sluice or highbanker faster than any bucket-top screen.
• Cleanup: #30–#100 fine mesh ahead of your Blue Bowl, wheel, or final pan.

Why Buy Gold Classifiers from Serious Detecting

Serious Detecting is an authorized US dealer for every brand we carry, including Garrett, XP, Minelab, and TerraX, which means factory warranties and real support, not gray-market guesswork. Orders of $99 or more ship free out of Michigan, and local pickup is open if you want to stack screens in person. The staff prospects: we know which mesh spread fits creek ground versus beach sand because we've shaken these exact screens over our own buckets. Tell us what you're digging and we'll tell you what to stack.
