My Leica rangefinder finally arrived yesterday by UPS. What a precision instrument! So small! This morning I took it out to a panoramic area on a causeway overlooking a reservoir. The speed of the calculation is incredible. Literally everything I ranged, reflective or not, was instantaneous out to about 1,400 yd. Beyond that, reflective bridge, abutments and trees already turned bright yellow got me out to almost 1800 yds. And it was a hazy suny day. Tomorrow I will test EHr component at a windmill farm. Being that the rifle I am using on my hunt in Utah this year( 300 Weatherby mag) outfitted with a Swarovski Z5 3.5-18-44P gets me out to 830, I could not be happier. When placed to side my old Nikon rangefinder, there is no comparison. Thanks again for all the reviews.
