Just walked back inside with my 10x42mm Leica Geovids, glassed clearly for deer in the North pasture up to the tree line at 600 yards, would need a small flashlight to spin the turrets in light that low.
This. My geovids are dang near night vision. I can often see deer with them that I can't see with the naked eye because it is too dark. They are expensive but you get what you pay for.
They're an amazing glass, and yes on the get what you pay for, but, mine we're free, won em on a bet.
Bud that lost the bet bought and had em shipped to himself first, looked em over, then left me a nice FU-!!!!! note in the box when he shipped them to me ;]
