XP Gold Classifier #5, 15 in (37 cm), 5 mm Mesh, Stackable

The primary advantage of the 5mm (1/4-inch) XP Classifier is its ability to rapidly sort out mid-sized gravel and debris, leaving you with a highly concentrated mix of fine sand and paydirt. By running your material through a sieve before it hits your primary gold panning gear, you eliminate the bulky rocks that cause fine gold particles to wash out of your pan. This smaller mesh size is ideal for processing fine creek gravels and concentrate cleanups where small flakes and flour gold are easily lost among larger stones.

Yes, this sifter is specifically engineered with an ultra-compact, nested design that interlocks flawlessly with the XP 15-inch #10mm classifier, the 15-inch XP Metal Detectors pan, and the specialized XP Batea. When nested together, you can perform a double-sieving action in a single motion. For example, stacking the 10mm classifier directly over this 5mm unit allows you to clear out large rocks and medium gravels simultaneously, leaving perfectly classified material ready for optimal gold extraction in a fraction of the time.

The XP 15-inch classifier is made from lightweight molded plastic, making it easy to carry in a backpack or prospecting kit. The stackable design means you can nest the 5mm classifier inside the 10mm classifier and the XP Batea pan, and the entire set takes up minimal space. Prospectors working remote claims or hiking into backcountry spots appreciate the compact carry, the XP system fits alongside sample vials, a magnifier, and a snuffer bottle without adding significant weight. The dual handles are molded into the rim, so there are no separate parts to lose on the trail.

You can use the XP 5mm classifier as a standalone sieve if your source material is already relatively fine or if you're reworking concentrates from a previous session. Set the 5mm classifier over a bucket and shake your gravel through it to remove rocks and debris before panning. However, most prospectors find that running the 10mm classifier first speeds up the process when working raw creek gravels or bench deposits, because the larger screen strips out fist-sized cobbles and reduces the load on the 5mm mesh. The two-stage setup is faster overall, but the 5mm classifier works fine on its own for smaller batches or pre-classified material. Explore more gold prospecting equipment to build your field kit.

The XP 15-inch classifier has a 37cm diameter and works over standard prospecting buckets. The rim rests on the bucket edge, and the dual handles keep the classifier stable while you shake gravel through the mesh. If you're using a smaller bucket, the classifier will overhang the rim, but you can still use it by supporting the pan with one hand while sieving. The large diameter is an advantage when processing high volumes of material, because you can load more gravel per shake and move through your sample faster.

The XP 5mm classifier works with both wet and dry material, though wet classification is generally faster because water helps break apart clay and wash fine particles through the mesh. When working dry desert gravels or bench deposits, shake the classifier vigorously to move the fines through the screen, and consider adding a small amount of water if clay balls are clogging the mesh. Wet classification at creekside is the most common workflow, scoop gravel into the classifier, submerge it in the stream to saturate the material, then shake it to let the fine gold and black sand pass through while retaining larger rocks.

Clay and decomposed rock can clog the 5mm mesh when working certain bench deposits or creek gravels with high clay content. To clear the screen, submerge the classifier in water and agitate it to break apart the clay balls, or use a small brush to scrub the mesh from the underside. Some prospectors carry a spray bottle to wet down dry material before classification, which helps prevent clay from binding to the screen in the first place. After a session, rinse the classifier thoroughly and let it dry before stacking it with your other pans to prevent residual clay from hardening on the mesh.

The molded plastic construction is designed for field use, including rocky desert washes and creek gravels. The XP classifier withstands typical prospecting conditions and can be packed in a vehicle with other gear. However, avoid stepping on the classifier or placing heavy objects on top of it when it's not stacked with other pans, as this can deform the rim or crack the mesh. The dual handles are molded into the pan body rather than attached separately, so there are no weak points where a handle might snap off under load.

The XP 5mm classifier will work over any bucket or container, so you can use it with a non-XP gold pan if you prefer a different brand for your final panning step. The classifier's job is to remove rocks and debris before the material reaches your pan, and it doesn't require a specific pan model to function. However, the stacking feature only works with other XP pans and classifiers, because the XP pans are designed to stack together. If you're using a different brand's pan, you'll need to transfer the classified material from the bucket into your pan rather than stacking the classifier directly on top of it.
