I sold my leica and currently have a Zeiss. Both work well but there are differences. The glass is good enough for both to identify hunting targets in low light, not much difference. The Zeiss is easier to hold steady but bigger to carry. The current Zeiss PRF has longer ranging than the old 900 series Leica but probably not as good as the newest 1500 model, although I have not done a comparison to the 1500 series. The Zeiss PRF will range a light colored cow at 900 but a brown one only to about 600. It will range reflective targets to 1000. If you are hunting at lets say 1000 yards, do not get the Zeiss. Mine does not have the range. My estimation is that the new Lieca 1500 will range farther but I have had to return 2 Leicas for failing to work so I am not enamored with their reliablity. My dealer also indicates that Leica is not easy to work with in terms of warranty. If you need to range farther than 6-900 yards that my Zeiss works on soft targets consider the The Leica and hope it doesn't stop working, get a Swarovski? or consider the new g7 br2. If it does what its advertized to do it will be the best out there for around 1500 bucks. Not been out long and not many good reviews yet, but it also has ballistic table function that works compared to the one in the Leica or Zeiss which is not usable for real accuracy. I did not get the BR2 becuse it was not released prior to my hunting season but if it does what its advertized to do, that's what I will get next. Good luck.
