The range finder I have now is rated for 600 yards. It's complete bullcrap. I can't get it to pickup my backstop (30'x8' dirt berm) past 400 yards. It works great for my archery hunting, but sucks for my rifle shooting. So I'm in the market for some new ones. What do you guys use. Here are the only musts I have...
Must read out past 1000 yards repetitively.
Under $1000
I have the older version of the Leica Rangemaster. It is supposed to read to 800 meters, however, I have had it read out to 1200 yards on reflective targets like road signs and billboards. The new version is supposed to read to 1600 yards.

I think that's the secret is what you are ranging and it's reflectivity. Trying to range a bush or tree at 1000 yds probably won't work to good.
My older Leica will range a leafy tree fairly consistently out to 750 yds or so, beyond that, it needs a little better reflectivity.
