Leica LRF?????\'s I have a Leica LRF 800 non-scan model. I took it out this morning and I could not get it to read in some instances. Other times it would give me different readings on the same target. Variance was between 8-24 yards difference. I was ranging a 12" steel gong that is painted white and a fullsize steel IPSC target painted white.On the 12" gong I got readings from 382-399 yards. It is aupposed to be at 400 yards. I could not get a reading on the IPSC target. It is at 600 yards. Both the targets were in the shade. Does this adversely affect the rangefinders abilities? I put a new battery in the rangefinder less than 2 weeks ago. If I do need to send it in to be checked, does anyone have that contact info?
