Layout mortises, mark shoulders, scribe circles—the Digital 3-in-1 Marking
and Mortising Gauge does everything a traditional gauge does and more. But
that's not all. As a digital gauge, it does it all with an accuracy of 1/1000th of an
inch. Versatile 3-pin design allows you to set up the gauge in several different
configurations, depending on the operation. Solid stainless steel construction.
