1500 yrd range finders
"After being able to use the Leica CRF, Saro Laser Guide and the Zeiss Monocular side by side last weekend I was pretty excited to try the zeiss more in the field. A friend sent me this handy calculator to figure the size of a beam at a given distance.
Here is the link.
pseudonomen137's JScript Diameter Calculator
Using this I computed the size of the beams of all 3 units at 1000 yards in to feet.
Leica 1200 CRF ........1 1/2' tall by 7 1/2' wide
Swarovski Laser guide........... 6' circle
Zeiss monocular.............. 6' tall by 12' wide
Looking at this it is easy to see why some will report longer distances more readily. Also how some may be giving you a range on something other than your quarry. Imagine how much stuff a 6' x12' beam will cast upon on flat ground. Getting those big numbers back is nice to look at. But,,, if you miss and don't know why maybe it was because you had a range on the bush 20 yards in front of the target instead of the actual target.
I am thinking if we are aiming small with the rifle,, we also need a rangefinder that will aim small too.
Just food for thought.

The 2 mils looks like a match from the info sent from Swarovski 2 mil =72 inches at 1000 yds The Zeiss beam at that distance is quite large but it sure ranges well! 30-338

I thought this was posted at one time, but didn't find it.
