Thank you, IdahoCTD & DrMike & others for your comments. I am always happy to learn about stuff, in this case, a lot of stuff about rangefinders. .
I realize now that I've been spending way too much time in the deep dark woods with little to no time in
flat open country. I'm going to dig out...
I got a Leica 400 yard one, some time ago, not sure if they still make them. The reason being was I wouldn't be taking 'the shot' past that range and that might have been the only one offered then. Never has failed, the eye piece is clear and sharp and it's small enough to fit in small pockets...
