You need to look into the Newcon Optic 1200 Range Finder at Midway. I used one this weekend shooting Prairie Dogs and it was spot on and very clear.
Easy to use.
I have a 400 yd Bushnell that will only pick up PDogs out to about 200 and deer to 250yds.
If it is a tree or building it will range to 400+. The Newcon is just a little bigger than the Bushnells but it sure is nice for the price. I will have one by next month.
