This sluice box is the perfect size for working a small stream or tributary. Anything larger would be a pain to haul around. It folds up, so can easily be carried into back country locations with the carrying strap. I will tuck it into a dry sack, though, to make sure I don't lose anything out of the mats on the way back out. High quality construction and mats. Lowest price I have seen anywhere for a box this size. Much larger than expected, even though the dimensions are listed in the product description. Very happy with this purchase.
