These are a MUST for any prospecting operation! These stainless steel classifiers have rugged plastic bodies with stainless steel screens. They are 13 Inches wide at the top and are tapered to fit in the top of a 5 gallon bucket. The overall height is 3 1/2" and designed to allow for 4 of the classifiers to be nested with an overall height of only 8 1/2". They are easy to use and a must for proper fine gold recovery.
