DISTO E7500i with Bluetooth The Leica DISTO™ E7500i is a 14 measurement mode LDM that is accurate to 1/16th of an inch. It is IP65 rated against dust, dirt and rain and features a point finder, a bright LCD screen, a 360° tilt sensor, and blue tooth smart. The E7500i laser module can read a target at distances that exceed your ability to see the laser point. With the point finder -- a 4x zoom digital camera -- you find your target in the display, extending the usable range to the ~ 650 ft max. The farther you can shoot, the more potential there is for something to get in the way.
