Once scale pads are level this laser projects a wide beam to show you a simulated ground plane (top of scale pads). This makes it easy to accurately measure ground clearance of frame, bellhousing, spoiler, oil pan, etc. Just like having an expensive setup fixture but easier to use. Complete setup includes self-leveling laser, adjustable laser stand, pad target and 4 magnetic chassis height tabs.
Comes with silver carrying case. Works best indoors. Bright sunlight may interfere with laser beam visibility
