i have the 10 x 42 ATB monarchs. other than the screw-out eyecups, they are great glasses. the eyecups messed up shortly after purchase and i have spent 2 years trying to get replacements. nikon customer service sucks!!
I've got a pair and they are ok but if I were buying today I would look very seriously into vortex. The guys on archerytalk just rave about them and after looking through a few pairs I would definitely get a pair of those over the atb's.
I have the 10x42 Monrch ATB's for around 10 years. They are a good Binocular, but mine is not as clear as they once were. It may have something to do with being dropped out of a treestand twice. I have used them and used them hard.
