It's not really that impressive. It can't image anything. Here are the demo videos.[1] This is a much simpler technology than millimeter wave imaging. It's one step up from metal detectors, but way down from Z-backscatter. Think of it as a metal detector with enough smarts to ignore coins, keys, and cell phones. It's probably going to detect a pair of pliers, but if you're bringing tools into a casino, the management is very interested.
