Factors to consider when buying a hunting binocular
Before buying your own hunting binocular, you have to take a look at some factors. Consider these factors as a basis in choosing the best equipment for your hunting activity.
This has to be associated with the objective lens diameter measured in millimeters. It is fine to use a 7x – 10x magnification because it is ideal for any type of hunting.
Objective Size of the Lenses
You normally see numbers, such as 7×40. The second number, which is 40 is your objective measured in millimeter. If you have a higher objective size, then you can see more details. But, if your lens is bigger, then the hunting binocular is also heavier.
Field of View
The Field of View or the FOV in measured in yards. This refers to your distance from the object that you are viewing.
The exit pupil is determined by the magnification and objective sizes. This the light allowed to pass through the eyes of the viewer. If you have a higher exit pupil, then you can visualize a bigger amount of light.
Relative Brightness Index
A Relative Brightness Index or RBI is equal to the square of the exit pupil. If you are hunting in a low light, then a 25 or higher RBI is needed.
Type of Prism
Hunting binoculars have roof prisms or porro prisms. A Roof Prism is reflecting light 5x, lighter, slimmer and directly lined with the binocular’s eyepiece.
