Stake out function Stake out equal or two different recurring distances
Triangle function Determine the area of a many-cornered room efficiently

Smart Horizontal Mode™
Thanks to the combination of distance and tilt measurements you can determine the horizontal distance precisely and simply. If you take a measurement at an inclination of ± 45°, the Leica DISTO™ D3a always calculates the shortest distance. So you can measure quickly and easily, even over the top of objects and people.

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
