Yesterday I bought a Leica D3. This model of the Disto includes an electronic inclinometer. At the same time as the distance is measured, the inclination is also measured, displayed and stored. Also, the inclination is continuously displayed as you alter the instrument’s position while aiming.
I’ll provide a report on this feature, and the whole instrument, after a little experience with it.
I suppose it is only a matter of time until Leica finally release a model that takes the compass bearing too. That would make it equivalent to the Disto-X add-in and the Shetland Attack Pony.
