Now with Bluetooth, a fully integrated intelligent endpiece, a bright white display and an ISO certified measuring engine that drives 1/16 accuracy and 330 foot measuring range. The Leica DISTO, D2 is a 7 measurement mode LDM accurate to 1/16 of an inch. It features an intuitive back-lit LCD display in a 4oz package that is small enough to fit in your pocket. Use Bluetooth to send measurements into apps running on mobile devices. The D2 measures from its base by default and can be configured to measure from the front. Flip out the intelligent endpiece to 90° to hook onto outside corners or extend the endpiece fully for inside corners. The D2 will automatically measure from the end of its flip-out endpiece when fully extended. Combined with the Min/Max function, the endpiece allows you to get the tool all the way into corners for accurate diagonal measurements as shown in this Intelligent Endpiece video. The D2 calculates area and volume, and remembers the last 10 measurements taken. Use the Add/Subtract capability to combine measurements to get a precise reading of the total wall area of a room aka the painter function. The D2 includes a Pythagoras function for indirect height or width measurements. However, in a tool this size that cannot be mounted to a tripod we recommend using the Pythagoras for estimates or rough measurements. If you need precise indirect measurements, an LDM with a tilt sensor is your best bet.
