Solid, very fast, versatile

The device is incredibly simple. The two laser points for sighting are very helpful. Almost immediately you get surprising results. For example, the place was a telephone system to locate unique tailgate doors alone on the small temperature difference on the door. Here is the absolute accuracy Weinger interesting than the high resolution. The temperature difference at a double glazing is good to identify from outside and inside .... No measurement has disappointed me.
Unlike other reviews, the current consumption with me 0.005 mA when switched off. This keeps the battery several years. That's OK.
