been wanting a gold cube for a long time, found one for sale at a price i could not pass up. all the material i had sitting on my back porch was already screened down to below 1/8 then i broke that down into separate mesh groups, this was before i got the gold cube, so i started clearing out the separate mesh batches (wont have to do that anymore with the gold cube) first gold i found was 50+, found a couple pieces in 30+, just ran some 20+ tonight found one nice little picker. not complaining, every piece of a gold i find is more than i had before. tried a lot of different sluices and machines to get the gold from my material but only the gold cube has found gold straight out of the box as it were.
