gold prospecting classifier
A classifier is a device that is used to screen out large and usually worthless rock into more manageable and hopefully more profitable gravels. Classifiers usually come as standard within gold panning kits. Larger rocks rarely contain gold (although it can be stuck to them), most of the gold will be found embedded within the smaller gravels.
