2. Check its flexibility. The flexibility of the binoculars can be tested if you move its barrels. This is very important so you won't have difficulties in holding it the way you want to. Make sure that the barrels are not tight so you don’t have to worry that it will break easily.

3. Test its focus. Most binoculars will not focus clearly when you test it inside the store because the environment tends to be dim. If you want to make sure that the binocular can focus clearly, try focusing it on a bright side of the room. If it has good focus, it will easily focus on the subject in sight. While checking the focus, you should also check if there are distortions in the image. If there is, don’t buy it because it is of poor quality.

4. Pay attention to its exit pupil. This should also be a major consideration because this will determine if you will see things clearly. The exit pupil refers to the diameter seen on the image once it leaves the lens' eyepiece. The exit pupil should always be bigger that the eyes of your pupil because the image will appear dark. The basic exit pupil should at least be 4 mm or higher to get the brightest image possible.
