I have the first version on the Vortex HD range finding bino, very happy with it and it is fast, love the different modes and it is fast. Ranged rocks at 2000 yards, and game at over 1000. I want the new one now, it has built in ballistics, Not exactly what you asked, but I am all about eliminating a piece of gear, with one that does 2 jobs. They did just release new stand alone range finders this year also if that's the route you want to take. I will say they have awesome customer service and made here in the states. The replaced the bino case for free after I tore the side mesh pocket. I called to ask about buying the new ARCA head for my summit tripod and they told me to ship it in to them, they changed the head and sent it back for free (all their idea).
