The Leica DISTO™ E7500i is a 14 measurement mode laser distance meter 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 Bluetooth 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 useable range to the ~650ft max.
The farther you can shoot, the more potential there is for something to get in the way. Smart Horizontal allows you to shoot over obstacles so you can measure the level horizontal distance to your target.
At distance, a small wobble in the tool bounces the laser point in wide arcs. This is sub-optimal for acquiring reflected laser energy. For best results when measuring long distances, keep your dot steady with a tripod.
