Don't get it!
Target is already in the ground, makes no sense to draw a vertical line through the target and onto the ground... I must really be getting old...

    Could it be so simple as this would eliminate the false reads of the BIG FAT Divergence #s (ie. BEAM SIZE) when they sometimes pick a limb or a rock in front of or behind the target? He could be going vertical to the nearest clean absolute earth?????? Just a thought.

    Divergence #s (ie. BEAM SIZE)
    Swarovski Laser Guide 8x30.............................2.5H x 2.5W millirads

    Zeiss Victory 8x26 T* PRF ...............................2.0H X 4.0W.Millirads

    Leica CRF 1600 ..............................................0.5H * 2.5Wmillirads

The only way I could know, was the Lieca hit them several times. Swaro would not touch them. But the Swaro would range the road bank at 1250 yards behind them. Like mentioned before, watch that beam devergence!! It cost me a trophy deer last year. I think they both have merit, but on flat ground I like the Leica 1200 CRF. If you are ranging trees, rock walls, or into hillsides, the Swaro will range farther. If you are ranging game on flat ground, DON'T over look the Lieca 1200 CRF.

    After talking to Jeff, back in June I think, this caused me to go with the Lieca 1600 CRF, for my application!

    T3-OleMan: LRF's... What a topic. Leica'a PLRF ($10,000.00) is my first choice.

    I have been using Nightforce's ADI (angle degree indicator) every since purchasing Nightforce scopes. I don't know which is better as the Nightforce program uses either in computing where to set the scope. They are a valuable tool in long range shooting and I use them on two different rifles. My .22-.250 VZ 550 and 300RUM custom.
