Product details (archived)

The information below is retained for reference only. This item is discontinued and cannot be ordered.

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.
