How to Choose Binoculars – Buying Binoculars
1. Binocular Magnification
The number, which is followed with “x,” is the magnification of the binoculars. You will see its written as 6x, 8x or even 10x. That means your binoculars will magnify the object six, eight or ten times respectively.
For example, if the hunt is 1000 meters away, it will appear as if it was a distance of 100 meters away as seen using naked eyes. For regular use, you should opt for, magnification between 7x and 12x.
That’s because anything beyond these figures will be hard to manage without using a tripod. In this image, we see a magnification of 7x.

You will find the objective lens on the opposite side of the eyepiece. Its size is important since it will determine the amount of light, which will enter your binoculars.
Larger diameter objective lens is best if you’ll be operating in low light conditions and want better images.
The lens size, which is in mm comes after the x. In relation to the magnification, a ratio of 5 is ideal. Between 8×25 and 8×40 lenses, the latter will provide you with a better and brighter image using its bigger diameter.

5. Binoculars Field of View/Exit Pupil
Field of View (FOV) refers to the diameter of the area, which is viewed through the binocular’s lenses and is expressed in millimeters, when image is at 1000 yards.
In this image, the FOV is given as 50, which means a diameter of 50mm when you look into this binoculars.
A larger field of view enables you to see a larger area. On the other hand, the exit pupil is the image, which is formed on the binocular’s eyepiece for your pupil to view.
The lens diameter divided by magnification offers you the exit pupil. a 7mm exit pupil gives you maximum light to your dilated eye and is best for dark and twilight conditions. If you use spectacles, look for a higher eyepoint.
6. Lens Quality, Coating
Lens coating is crucial since it reduces the amount of light, which is reflected and enables maximum light to enter. The lens quality, on the other hand, gives you a better contrast and ensures the image is aberration free.
The best quality lens will work well in low light conditions since they transmit more light. They also make sure that colors aren’t distorted or washed out.
