Good Range Finder for bow hunting type distances

[Brad34340]

As the title suggests I'm looking for opinions / suggestions / experience with a range finder for bow hunting.

Something small, accurate and functional in wooded areas where primairily I'll just be looking to range my surroundings 20, 30, 40 yards -- that kind of thing.

I absolutely don't need the unit to be capable of ranging targets hundreds of yards away ... or even a hundred.

Thanks
