XP Metal Detectors 15" Classifier Set with #10mm and #5mm Mesh for Gold Prospecting

The XP #10mm classifier is the coarse first stage that strips out rocks larger than 10 millimeters, while the #5mm classifier is the fine second stage that refines the concentrate before panning. Prospectors run material through the #10mm mesh first to remove fist-sized rocks and large gravel, then sift the remaining material through the #5mm mesh to catch pebbles and coarse sand. This two-stage workflow isolates gold-bearing material faster than a single-mesh system. The dual-mesh approach is standard in high-volume prospecting, and our gold panning guide walks through the full classification process.

Yes, both XP 15-inch classifiers stack inside XP's 15-inch gold pan for compact storage and transport. The nested design lets you carry the full sifting and panning kit in a single unit that fits in a backpack side pocket. XP's totally stackable design means the classifiers nest inside the pan when you're packing up, making the system very easy to transport and store together. This stackable system is one reason prospectors choose XP's prospecting line over competitors that require separate storage for each piece.

The XP 15-inch classifier's large diameter handles more volume per cycle than smaller 10-inch or 12-inch classifiers, so you spend less time shaking and more time recovering concentrate. Prospectors working high-volume creek deposits or dry washes prefer the 15-inch size because it cuts processing time on heavy gravel loads. The 37-centimeter diameter provides substantial capacity for field applications, letting you process material efficiently without constant reloading. The trade-off is slightly more weight and bulk compared to compact 10-inch classifiers, but the speed gain justifies the size for most prospecting operations.

Yes, the XP classifiers work with any standard sluice box as a pre-classification step. Prospectors sift material through the classifiers before feeding it into the sluice to remove oversized rocks that would clog the riffles or bounce gold out of the box. You can classify into a bucket and then shovel the sifted material into the sluice feed. This pre-sifting step improves gold recovery rates in sluice operations by ensuring only appropriately sized material reaches the riffles. The 15-inch diameter provides ample capacity for processing material before sluicing.

XP's polymer classifiers are lightweight and comfortable to use, making them easy to transport on long hikes to remote claims. The weight savings matters when every pound in your pack adds up over miles of trail. Polymer classifiers also resist rust and corrosion in wet storage, so you don't need to dry them completely between trips. Steel classifiers are more durable under extreme abuse, but for most recreational and small-scale prospectors, the XP polymer build offers the better balance of weight, durability, and corrosion resistance. You can explore other sifting options in our classifiers collection.

XP's polymer construction is designed for durability in field conditions. The classifiers are lightweight yet built to withstand the demands of prospecting work. The polymer's impact resistance protects against drops on rocks, which is a common failure point for brittle plastic classifiers. The mesh is securely bonded to the frame to maintain integrity during regular use. While specific cold-weather performance data is not provided, the durable polymer construction is engineered to handle typical prospecting environments. Prospectors should handle all equipment with reasonable care in extreme temperature conditions.
