Got my hands on this unit just 2 weeks ago, I would like to comment beside all of the regular Kahles features (light transmission, illumination adjustment) the unbelievable field of view @6x magnification. I would personally use this scope as driven hunt scope, since I am not in any correlation with the tactical/spec ops field.
The only thing is for the same price you can get a fragile Swarovski Z6i, but I personally would choose a tactical version from this Austrian manufacturer.
And the red illumination element in the SI-1 reticle is perfect for hunting purposes.
Pros: filed of view, lens coating, illumination color
Cons: no auto on/off illumination, price level
