I thought I'd developed cataracts! I am overdoing it a little.
But the glass is really pretty poor compared to Leica, Swaro,... I think worse than the Bushnell 1500 Arc also.
You won't want to use them for spotting like I do with my Swaros. I commonly use my Swaros to spot game. They double as a very high quality monocular.
To be upfront, I never used the Newcons in the field. I looked at, and through, them inside a 10-acre size building at Shot Show 2007 in Orlando. That's when I decided I'd cough up the extra dough for the Swaros. I already owned a pair of Leica 1200 Scans at that time.
Be sure to read this recent Thread. There's some mention of the Newcon Rangefinders (not positive) that will be of interest to you.

Good shopping and good luck.
