I couldn't see them either. If they are the AKA, been there. The Signum is one heck to a detector. They use a metering system that is second to none called a hodograph. Kind of beyond my price range, but some consider them the deepest detectors with the fastest recovery rate.http://akadetectors.com/products.php?page=aka-signum-mft-7272mAll the video's are at the bottom of the left menu.
