Now, I want to make it clear that the range finder is not like one for golf with a red dot and gives you the distance, its more like a scale that is inside the lens and you have to figure out the size and range of the object. So basically, The range-finder feature is not a laser, but requires you to do some math — you will need to know the size of the item you are looking at.

Thanks for the reviews. In assessing binoculars for low light use, the jet is a 7mm exit pupil, which corresponds to the average human pupil when it is at full dilation in the dark. This, allows the ey to observe all light that is transmitted by the lenses. So
10×70… Etc
I’m certain that you know to divide the objective lens power by that of the Dia of exit pupil.
