I have a Nikon Monarch Laser 800. I do quite a bit of rifle long distant shooting. I really like this range finder. Works good in low light, fog, and rain. No problems with it at all. With unmatched 1/2 yrd accuracy. You might not need one that goes out to 800yds, but they do have one that is 400 or 440yds. (in black-under $200, Cammo model-just over $200). I think this would suit you better. Might be worth checking out!
my replies consist of my opinon, my $o.o2 worth, take it or leave it!
