My Zeiss Victory 10 x 45 rangefinder binos gave me readings off trees at over 300 yards through my raindrop covered, curved, pickup windshield yesterday. They have been flawless during the several years (can't remember how many) that I have owned them, and they were pre-owned when I bought them. Two of my best bucks and countless coyotes have died, that definitely would not have otherwise, because I didn't have to switch from binos to rangefinder, and I have played the game both ways. Try switching from binos to rangefinder on a rutting buck at the outer limits of your firearm while lying prone using bipod and turning turrets. Once you've had both in one unit there's no going back, unless you want less taxidermy costs. LOL
