The Zeiss PRF im using is working very well for me... it ranges animals, trees, grass, dirt and rocks out to 1400yds in midday sun very reliably. The only things it wont range this far are black objects and black animals.... it just doesnt like black things at all...
I love the Zeiss range finder bino....I tested the smaller one and the larger one. The larger one seamed to range very well out to about 1,450 yards. And the optics,,,holy cow,,,I plan to sell my swaro EL so I can buy this unit. It has HD lenses and you talk about sweet on the eyes. This unit is oh so easy on the eyes.
When I test range finders, I will not spend the time on any metallic objects, buildings, water towers etc. It's a waste of time for me. I only range trees and dirt hill sides. This is what counts in the field.
