Nikon Prostaff 550.
It can detect solid isolated targets well into the edges of 600yards. It DEFINITELY grabs accurate distances on good objects to 550+ yards. For softer, smaller targets, ideally you range a solid object close by.
Take a coyote for instance: I can range a dog at 150yards on flat open ground. Beyond that, I need to hit a tree, rock, hill to get a read. But a deer, I can ping a deer at 250yds, even 300 if the animal is still and in the open. (Denser, heavier body, elevated off the ground, and shorter fur to reflect the signal.) I can range a cow or a horse at a full blown 500+ yards.
While I have used rangefinders of 1000yd when shooting, and 10,000yds in the past, they are just not real practical for hunting and target shooting, for a couple reasons: 1. A deer, elk, moose is a maybe for a hit out to 1000 yards. A moose, you can read that. But smaller animals are not dense enough to give a good reading. (Hogs, deer, and anything smaller.) 2. When target shooting, you generally know your range if you are looking into shooting anywhere near 1000 yards. You tend to set it up in advance. (For that purpose, the rangefinder IS the ideal way to do it.) But for saying "I'd like to shoot that rock way out there, wonder how far it is..." When you are looking into those kinds of distances, there are many more factors to accurate shooting, so the rangefinder becomes slightly less relevant.
An absolutely amazing tool, when hunting and working the 300-600yd range. The Nikon is well worth the price; affordable and works.
