The device is intended that fixed it for the purpose of fast orientation somewhere on backpack or anywhere else. The carbine is obviously made of metal (usually the 24 g weight would not be explainable), and not just any plastic part that breaks up under stress. Carbine have the opening always on the larger side, this reversed. Thus it can also be enjoyable even in a buttonhole or the perforated slide of Zippverschlüssen einhängen.Das whole is also designed so that you can place the device on a flat surface, and not blocked despite the difficulties, the compass disc.
The compass is of course not for precise operation Suitable: It is indeed just that you know about so where north is when the sun is not visible, it was in a strange city, under an overcast sky, or at night. And one can thus also about eg define a line of approach.
The scale is not divided into degrees, grads, or nautical lines, but in 64 times 100 Artillery per mil. For my purposes, that's ideal: A white bar (400 Artillery per mil) is about 400 m deviation from the target is 1 km away. With such a simple device other subdivisions would mE no sense.
The three star deduction's with a heavy heart for the thermometer: This is fantasy values. I initially thought it would just slow to react, but I've just taken out of the freezer and cooled down to 17 ° shown, and now it is 25 °, although it has 21 °. In the office the device, however, has shown the afternoon very carefully the 27 ° ... Something as apparently screwed up mechanically.
I am not a control freak, and I do not really care if it now has 25 ° or 21 °. While camping but for me the interesting rule of thumb (if the weather remains fairly constant) that the dew point in the evening the minimum temperature quite well foretells at night (ground frost? Campfire?). Measuring dew point is not a problem: Thermometer dive into the water, the water evaporates and cools the thermometer off to the dew point. This is all, of course, very roughly, but with the thing ...
