The monocular has a large aperture and a large magnification, which is also a great advantage of the monocular, and it is also its most attractive place. Of course, some single tubes are very small, even smaller than the larger double tubes, which look light.

Binocular has a small magnification, but their field of view is large, and their visible range is much larger than that of monocular. Night vision thermal binoculars are portable and flexible, hold them in your hand to observe the world and the earth, and can quickly change the viewing target. Binoculars look with both eyes, and what two eyes see is faster than what one eye sees, and the brain can analyze and recognize it faster. Although holding hands with both hands is not stable, it is not difficult to solve the problem: crouch down or sit down with your elbows on your thighs or lean against the wall.
