Anyone try one? I returned a Pentax Gameseeker due to not being able to get it to focus at max range and they sent me one of these in exchange. It is much heavier than the one I returned due to the battery and motor. My main complaint with the "switch" is the diameter of the tube. This one has a 30mm tube where the rifle I was using this scope on has one inch rings. Seriously thinking about trying to off load it and use the proceeds towards another Nikon but wanted to know if anyone has actually used one and what they think of it. Thanks in advance.
