Im very interested in what a monocular is, Im wondering whether I should buy it or not, what is its function?

 

Look, the binoculars have two eyes, but the monocular only has one, that’s all great. I personally find it more convenient to carry a monocular https://www.atneu.com/thermal-monoculars. I use it when hunting and detecting prey. You can attach it to your helmet and it will be comfortable to wear. It's small and modern!
