Here's the deal with the Leica Geovid-B
in my eyes:
1. Minimun distance is such that a bow hunter can use it.
2. Uses the same ballistic technology that the 1600b uses in the fact that you can use 12 pre-programed ballistic curves to give you a shooting solution (1/4 moa or mils)
3. mini sd card that can be placed in the unit to work off of specific ballistics.
I use the Swarovski EL range
myself. It's a great unit. I've been pleased with its performance both optically and in it's range finding capability. Honestly I don't care if it's not HD because I can't really tell the difference between it and the EL's with swarovision.....even in twilight.
IMHO they are again setting a benchmark in the market place. Superb optics coupled together with intuitive design.
