Wow! I just got my Disto D3 and it is nice! We will be using it in-cave in mid January but here are some pics.
Also note that it measures +/- 50 degrees not the 45 degrees it states in the manual. It also is very easy to steady the inclo and get a good solid read with the touch of a button for distance and inclination.
The bottom 2 pictures also show the bracket that pops out. When this is extended the Disto automatically senses that and adjust the measurement accordingly.
Just one word......FANTASTIC!
They are in stock now at http://www.laserstreet.com/leica-disto-d3.htm and remember to put in the code "cavers" for a caver special price.
