There’s no doubt that you will be impressed with the Gold Cube and we love to hear it! If for any reason you have a problem please call.When deciding which Gold Cube to use (3 Stack or 4 Stack), there are several factors to consider: price; size (footprint); and the type of gold you may encounter. Many gold prospectors with the typical sluice box have witnessed that very flat gold (glitter gold) has the tendency to drift or “sail” over riffles. This is because flat gold lends itself to slight current manipulation and water surface tension that may allow it to float. The Gold Cube design eliminates surface tension in what we call the “G-Force Separator”, which forces everything below water under a gate. This breaks the surface tension and forces the gold to the bottom of an axial trough. The combination of gravity and hydraulic pressure makes it impossible for the gold to float or sail.To illustrate this — If you were to drop a flat washer and a steel bearing, both weighing the same, into a swimming pool at the same time, the steel bearing would hit bottom, first. In the same way, the flatter the gold; the more time it takes to settle. Location is not the only factor to be aware of, though we have found that there are areas where the gold is typically very flat. Keep in mind, it is all about the shape of the gold, and not where it is located. Many placer areas close to the source have gold that is chunky, roundish, and not flat. If you plan to limit your mining to this type of area, then a 3 Stack may be your machine. You can add a tray, later, if you decide to go to the beach or find a tailings pile with super-fine gold. The beauty of the Gold Cube is that you can always add a tray, trommel, or a Gold Banker when it becomes necessary.
