So many retarded takes in here.
I use binoculars for my job.
You wouldn't use monocular unless you wanted to save weight for camping or hunting, or get a real quick shot of something because you had it in your front pocket. I wouldn't recommend them besides that. Their field of view isn't great, and that is something you do want if you are zooming into what the fuck is that out there 300 yards.
Now here's the part people don't like to read because it tests their manhood. Most people can't stabilize 10x enough to get its full benefits. The higher the zoom, the worse the field of view. Some brands especially have a shit for. The average person buys 8x or 10x. You need to know what you are using it for. Are you trying to count the prongs on a buck and the health of your kill in Montana or looking 100 yards across a field to watch a bird. Can you stabilize against a tree, the arms of a chair, a fence, or against your chest. You can also get a monopod or tripod for like 12x+. You want much more if you are watching stars.
There's two binoculars designs: porro and roof prism. It is how the reflectors angle in the binoculars to get their zoom. The old style is porto as they are much wider. It's the type that gets wider at the tip. Refer to post 4. Roof is newer design, and more compact like pic 1.
Roof tends to be more expensive, more compact and portable, and needs more light for the same clarity.
Porro needs less light for same clarity (the 8x34 part can be lower), tends to have wider view in my experience, and tends to be cheaper.
There's also inverted porro that looks like something out of star wars in that hoth battle, but it's infrequently used.
