The ideal binocular is a 7X50. This is what the military uses.
Its a 7X binocular. They will always give you the magnification followed by the diameter of the lens, so a 7X50 is 7X with a 50mm lens.
This is very important, because when you divide 50 by the 7X, to get the exit pupil of the binoculars, you come up with 7.1mm as the answer. The exit pupil is essentially the diameter of the channel through which light, or the image you see through your binoculars, travels through.
The pupil of the human eyeball, when it dilates in darkness, can open up to about 7mm. Thus the 7X50 has an exit pupil that is equal to your pupil diameter in darkness. This greatly aids you when you use your binoculars at dawn or dusk, or in darkness.
Can you give me a few Mfg suggestions to help my decision? I'm not sure what all you just said but I'm convenced you know what you are talking about.
