It fits both my standard walls (5/8 drywall instead of 2x4) and deep scans to my very thick walls (1/2" fiberboard + 5/8 drywall + 2x1/2" " Drywall. If you read the instructions and understand how the device works (detects the change in density behind the wall), then you probably can't go wrong, which generally gets the best reviews.
