The Leica DISTO™ E7100i is a 3 measurement mode LDM with a 200' range that is accurate to 1/16 of an inch. Its small, weighing in at 3 1/4 ounces with batteries, very easy to use, and the E7100i sends measurements via Bluetooth making it -- by far -- the least expensive Bluetooth LDM available.
The ability to send distance and area measurements to mobile apps as you take them makes the E7100i the ideal tool for generating estimates, or inputting accurate interior measurements into modeling software on-site.
