Device

Leica Disto d810 Touch is a laser distance meter with up to 200m range and full inclination. The build-in compass cannot be used for surveying as Leica put it:

The compass is useful for answering questions like, "Wait. Is this the north elevation or the west elevation?" or "Which way am I facing?"
