Magnification
Also called: power, zoom, 8x, 10x
How many times closer an object looks. An 8x binocular makes something 800 yards away look like it is 100 yards away.

What it is good for
- Picking binoculars you can hold steady.
- Choosing a scope power for your range.
- Matching optics to the job.
Where it falls short
- More is not always better.
- Above about 10x, most people need a rest or tripod.
- Heat shimmer limits high power on hot days.
Tips
- 8x is easier to hold steady and gives a brighter, wider view than 10x.
- Try before you buy, and look at a far object for a minute.
Works well with
- Field of View: shrinks as power rises.
- Exit Pupil: gets smaller as power rises.
Field notes
Power magnifies the image and your hand shake equally. A steady 8x is often easier to use than a shaky 12x.

Specs here are typical, not guarantees; models differ, so check the maker's published numbers. Never look at the Sun through any optic without a certified solar filter, and zero or mount a scope with the firearm unloaded and pointed in a safe direction. Rules on optics, such as scopes on certain hunts or lasers and electronics, differ by state; our state resources directory links to each state's official regulations. Want a buying guide?
