This sluice box is a 16 foot by 40 foot, multi-stage step down gold sluice box was designed with our typical computer aided software and mathematical equations that we use for all gold recovery systems. We also incorporate any new proven scientific discoveries and work side-by-side with specialists, like Freddy Dodge, who has more fine gold recovery experience than most any one person in the world. This particular sluice box was built for the TV series Gold Rush and shown in season three episodes. When in its design stage, Freddy thought we should nickname it "Big Red" and the name stuck.
