With the integrated digital Pointfinder with 4X Zoom, the Leica DISTO D510 easily and accurately takes measurements in unfavorable light conditions. Ask anyone who has tried to measure outdoors on a sunny day – this function is priceless. Even when laser point is no longer visible to the naked eye, the target can be seen perfectly in the crosshairs in the Leica DISTO D510 display.

You can take a measurement and the Leica DISTO D510 will then automatically calculate the shortest horizontal distance allowing you to measure quickly and easily, even over the top of objects and people.
