The new Leica DISTO™ D3a with Smart Horizontal Mode™ for precise measurements is the newly uprgraded multi-functional instrument combining accuracy and reliablity with software enhancements developed for more expensive instruments

Replacing the older Leica DISTO™ D3 the new unit offers even more features inside an updated ruggedized body able to withstand even the toughest conditions.

With a measuring accuracy of ± 1.0 mm, the Leica DISTO™ D3a offers high precision at the touch of a button and with the large, illuminated display the measurement results and supplementary information are clearly and legibly displayed.

Multiple functions
The Leica DISTO™ D3a can calculate rectangular and triangular areas, volumes, room dimensions and various types of Pythagoras functions. A time delay release and enough memory for up to 20 measurements round off the instrument’s wide range of functions – a concept designed to make your work life easier.

Multifunctional endpiece
Aim the instrument straight at the target point, whether measuring out of corners, slots or from edges: with this endpiece you are prepared for all measuring situations. The instrument detects the endpiece automatically, which helps you avoid expensive measuring errors.

Power Range Technology™
The integrated Power Range Technology™ makes measuring long distances very easy. You can measure up to 80 m without a target plate and even up 100 m with a target plate, without having to take single step.

Brilliant and clearly arranged display
The results are displayed on the large (2”), clearly arranged and high contrast display. At the touch of a button, the display makes supplementary information available about the measurements, e.g. indirect height, room dimensions, angle information or room angles.
