Does anyone have any experience with these scopes? They combine a laser rangefinder with a rifle scope and it only weighs a couple ounces more than a comparable scope. Zeiss has a respectable name in the optics space so I'm guessing the quality is good. They have two models. The 3-12x56 looks interesting but I'm a traditionalist and I'm wondering if this is just a bunch of unnecessary bells and whistles or does this scope really deliver. Thanks in advance for your comments.
