5 reasons to choose a Leica DISTO D3a instead of a Leica Disto D2

  1. The Leica Disto D3a has twice the power of the laser with a range of  100 Metres
  2. The Leica Disto D3a is also small, but has the added tilt sensor for accurate hand held measurements
  3. The Leica Disto D3a has a greater level of accuracy  ± 1mm
  4. The display on the Leica Disto D3a is larger, clearer and has additional added information available such as perimeter areas and indirect height measurements.
  5. Both are designed for indoor use, however the Leica Disto D3a has a greate power of laser. So if you can see the laser, you have a greater chance of obtaining an external measurement.
