Binocular is a device that helps to observe remote objects with both eyes at once with the help of two telescopes. Due to it a person can get a full stereo image, in contrast to the use of a telescope, which performs, generally speaking, the same functions.
You can choose waterproof binoculars with a 10x zoom and image stabilizer in your inventory. This object can hardly be overestimated, thanks to it you can watch border guards. If you see their silhouettes, then you still have a chance to escape. In addition, they will not notice you, because the lenses do not flare.
Using a binocular you can search for a place to sleep.
In addition, a binocular can be used simply for aesthetic pleasure, for example, to look at the extending landscapes from the mountain top.
