Last weekend I picked up a Nikon Monarch Pro 800 rangefinder. All I can say is WOW. What an awesome product. They promise capability to 800 yards and 1/2 yard accuracy to 400. I'm getting half yard accuracy well past 400 yards on black spruce trees and ranged a building at 1009 yards the other day. I thought something was wrong at first when I saw "1009" in the scope, because the last digit is smaller than the other three (generally this is the <1 yard decimap place). Then I noticed that there was no decimal point before the nine, and other objects between me and the building ranged accurately.
It seems rare these days to find a product that performs as well as the manufacturer claims, but in this case it looks like it actually exceeds the claims. I haven't nailed down the limit for a non-reflective target yet, but I know it's way out there. All this in a product that will fit in a shirt pocket.
