Welcome fellow prospectors! This site is dedicated to our hobby and finding more GOLD! This classifier was designed to SAVE YOUR BACK and move more material. Never stoop, squat or SHAKE A BUCKET AGAIN!  Enjoy the site and videos.   We know you'll FIND MORE GOLD using the "Earthquake".
The "Earthquake" vibrating  bucket classifier is extremely effective for screening both desert and river material.  The classifier is built with a UV and water resistant coating. 
As your back well knows, the secret is to MOVE MATERIAL.  The "Earthquake" will classify a 5 gal. bucket of dry or wet material in 3 to 5 minutes,  and no stooping, bending or bucket shakin'! 

Even the kids get involved!

This is the "Earthquake" in action.  These are all un-edited videos.  We are prospectors, not movie producers!
In these videos, we are stacking 2 Keene classifiers.  A #2 (1/2") on top and a #4 (1/4") below. 
We even found a dime!!

The EARTHQUAKE is THE machine for fine gold recovery.  Easily classify all the way to -100 mesh.  If the particles aren't the same size, they won't separate.  Look how easy it is.
