Compact laser rangefinder

It is very compact rangefinder: 10x 4.2x2.2 cm. Much smaller and lighter (less than 90 g) a model of another brand I have. It hardly takes place in a pocket. In addition it comes with its cover.
It offers all necessary functions such as continuous measurement, the sum or difference of distances, surfaces or volumes It can set start measuring from the back of the case or the beginning (laser side).
Few keys. A touch sweeps the different modes by pressing repeatedly. The screen indicates how well you are.
Its range is 30 meters outside but it's always the same problem to follow the beam. Yet a measure "blind" by targeting a barrier without being certain to reach him, gave an exact measurement.
Precision is at the rendezvous. A Bluetooth interface allows to do communicate with a smartphone or tablet either in or under iOs Android. Pairing is done only once. This allows measures to repatriate in the Bosch Application free download and start a project. In the first printing, the software does not seem very friendly although it can import photos. I still groping and I will need a good tutorial that I have not yet found.
But as I ordered it to take action, I am fulfilled. Too bad if paper, eraser and pencil will still be useful.
The price, almost 100 at Amazon, the place in the high-end features but saw its investment is interesting.
