XP Metal Detectors 15" Classifier #10mm for Gold Prospecting

The XP 10mm classifier removes rocks and debris larger than 10 millimeters in diameter, trapping oversize material on the mesh while allowing finer concentrate to pass through into your pan or bucket. This mesh size is effective for initial classification when you're working stream gravels with a mix of pebbles and sand, it strips out the bulk of non-gold-bearing rock so you can focus on processing the fraction that actually holds fine gold. Prospectors often follow a 10mm classification pass with a finer mesh screen to further grade material before final panning. For guidance on building a multi-stage classification system, see our gold panning guide.

The XP classifier is designed to stack directly with XP gold pans and other XP classifiers, creating a nested sifting system without separate frames. The rim design nests with XP pans while you shake material through the mesh, and you can stack multiple classifiers with different mesh sizes to build a multi-stage grading setup. This stackable design is compact for transport, the classifier, pans, and additional screens nest together in a backpack or prospecting kit. The ultra-compact design makes the entire system lightweight and easy to store, with all components fitting together efficiently for field use.

The 15-inch diameter handles high-volume material efficiently, making it well-suited for solo prospectors working productive pay streaks where you need to process bucket loads quickly. The wide opening reduces the number of sifting passes compared to smaller classifiers, which speeds up your workflow when you're moving a lot of gravel. The frame is lightweight enough for one person to shake comfortably during extended sessions, though the larger diameter does require more space in your pack than a compact 10-inch classifier. If you're hiking long distances to remote sites, consider if the size advantage justifies the extra bulk.

The XP classifier is constructed from lightweight prospecting-grade plastic with a mesh screen tensioned across the frame. The material choice keeps the classifier light for transport and comfortable to use during field sessions. XP does not specify the exact plastic formulation, but the frame is designed to integrate with the XP gold pan system for prospecting use. The lightweight construction makes the classifier easy to handle during extended classification sessions while maintaining the structural integrity needed for sifting gravel and rocks in the field.

Rinse the XP classifier with clean water after each prospecting session to remove clay, silt, and fine particles trapped in the mesh. Shake the frame while rinsing to dislodge material stuck in the openings, and use a soft brush if clay has dried onto the mesh. Avoid using metal tools or abrasive scrubbers that could damage the mesh or widen the openings. Let the classifier air-dry completely before stacking it with pans for storage, moisture trapped between nested screens can promote mildew in warm conditions. Periodic inspection of the mesh for tears or stretched openings ensures consistent classification performance over time.

The XP classifier works as a pre-classification tool before feeding material into a sluice box, removing oversize rocks that would clog the riffles or displace fine gold. Set the classifier over a bucket, sift your raw gravel, then run the classified material through the sluice. The 10mm mesh removes oversize material before sluicing, and prospectors working very fine gold sometimes follow with a second finer classifier to reduce the load on the sluice. The classifier is a standalone sifting screen designed to integrate with XP pans or sit over a collection bucket, allowing you to process material efficiently before running it through your sluice system.
