The Garrett classifier is funnel-shaped; this causes the material to feed quickly to the bottom, wet or dry. The round design accelerates material flow through when we use a twisting motion, rather than the tiring side-to-side shaking motion. The legs extend below the bottom so that when a small gold pan which is 10½ -inches or even smaller is used, the classifier can be located on the top and the legs will lock around the outside part of the small pan. The two vessels subsequently remain firmly together as you grasp them with both hands to use the twisting motion that rapidly separates the large and small pieces of material.
The Garrett Classifier is in the same manner, quite exceptionally easy to use with gold pans which are larger than 10½ --inches in diameter. The peripheral 1egs have a pronounced slope which makes it possible for the classifier to be positioned on top of any large gold pan. What you must do is to set the classifier on top of the pan, you must grasp it and the gold pan together with both your hands, and after that use a twisting motion to cause flow through of wet or dry material. If you see that water is available, make sure to keep the classifier and the pan under the surface.
The classifier also fits perfectly over the commonly used five-gallon plastic buckets in which a lot of products are now marketed. These buckets, while we're on the subject, have become a roll-over prize for both, the prospector and the gem hunter. Dredge operators use them to carry dredge concentrations home for later panning; gem hunters classify the material into them for later examination; dry wash or dry panners dump the heavy concentrates into them for later wet panning. This everyday, plastic bucket is in all probability one of the most used, though apparently non-prospector related, tools in the industry. The material is shoveled or dumped into the classifier; the classifier is held over the top of the bucket and worked with the twisting motion. You save carting home all the oversized material. The Garrett classifier will also fit into the mouth of larger plastic buckets.
Dredge operators pour out their sluice box into the classifier, they hold it under the water to put the material in suspension directly over the large gold pan or plastic bucket, and give it a few speedy twists. They then remove the classifier from the water to examine the large rocks visually for the presence of nuggets; they also discard the remaining material, and take the smaller concentrates for later panning home. It is important at this point to note that the classifiers which contain an irregular hole size, possibly even stretched out, allow a great deal of the excess, unnecessary material to flow through, creating added labor on the final clean-up.
