This is the older version. I paid too much for it. Here it is for 202.00:http://www.packsandtents.com/product...52dWd-FOV.html
The diopter keeps moving and it doesn't focus as sharp as the Zen Ray.
I'm a tiny bit suspicious if Krueger really "engineered" this binocular when Adorama had/has an identical diopter design for quite a while. I already had one of these and it was defective and I returned it. I thought the diopter looked familiar..
Pic below is Adorama's Pro-Optic
However, I really like the focus dampening. There is a little play but it's very easy to move.
