Had a really great conversation with Dave today at the harrisburg show. I also got to see the "thing" in action... way to cool!!! This is definitly the slickest thing for a long range shooter. Basically if you don't have it you don't have all the toys and gadgets that go with this sport. I would say within 2 - 3 min ( time taken for data imput ) you have your clicks ( or mils ) as well as windage adjustments you need to aim and shoot Dave if ya get a min. shoot me an e-mail on how and where I can get one. Also gimme an e-mail address for your buddy that was along with ya. Great talking to ya.
