I am looking at purchasing a RF binocular. I currently have a Swaro RF and it works great, but I want a binocular that does both range finding/glassing. I am looking at the Leica Geovid 10x42 RF and the Zeiss 10x45 RF. My Swaro will go out to 1500 yards, do either, Leica or Zeiss RF bino's compare? Does any on have experience with either of the two RF bino's mentioned and is one any better than the other?
