A practical tool, Born out of necessity... The inventor, Bob Alvarez, a Sea Captain and gold miner who was based in Alaska, saw a need for a faster, more effective classification method. After all, everyone was using five gallon buckets because they are handy, portable and easy to work with. The GoldSlinger, unlike similar home made bucket classifiers, has patented technologies with hydraulic jets, quick change screens, optional Snappy Grip handles and smooth glide fit buckets.
The classifiers for gold prospecting and gem hunting come in several shapes and sizes. We have the typical 14 classifier that is used atop a 5 gallon bucket.
