The D2 offers multiple modes of measurement that are useful for many different kinds of projects: distance, min/max, permanent, stake-out, add/subtract, area, and volume, and it includes painter and Pythagoras functions. An intelligent endpiece enables you to measure accurately from outside or inside corners, including diagonal measurements. The D2 calculates area and volume, and remembers the last 10 measurements taken. And a back-lit LCD screen makes it easy to read while you're on the job. The D2 measures from its base by default and can be configured to measure from the front. You can also flip out the intelligent endpiece to 90º to hook onto outside corners or extend the endpiece fully for inside corners, and it will automatically measure from the endpiece when extended. Combined with the Min/Max function, the endpiece allows you to get the tool all the way into corners for accurate diagonal measurements.
