Disto Laser Distance Measuring Meter 325' (a3) by Leica GeoSystems

Model #: a3

The Leica DISTO™ a3 is the smallest (5½" long) handheld laser distance measurer available to reach such measurement ranges.

Minimal size and simple operation are the defining characteristics of the basic model. Shortcut keys for addition, subtraction, area and volume mean that measuring could not be simpler. Minimum and maximum functions have also now been incorporated. You could even say that this compact unit is a joy to use.
