This popular green plastic sifter or classifier screen fits in the top of any common 14″ gold pan, separating rock from gravel for more efficient panning. The effort saved is immense and the chance of gold loss reduced – no person panning gold should be without this essential tool. The Garrett Classifier also fits in the top of any standard 5 gallon bucket, allowing you to remove the heavy oversize material when carrying buckets of gold bearing material to a sluice box. There is no use in hauling those rocks only to have to toss them out of a sluice later on. The screen even finds use when metal detecting for coins and relics, as the 7/16″ square holes will sift smaller trash while retaining dime size and larger items.
