I went with the binocular style LRF because as one other reviewer stated: it's less straining on your eyes and for me, after having shoulder surgery, i can't seem to hold the monocular style LRF steady. I'm not sure if there is a problem with my particular unit, but after installing a new battery I ranged maybe 6 targets for maybe 30 seconds each and then stored the unit for about 1 month. When I went to use it again, the battery was dead! And this wasn't the only occasion, I've gone through 3 batteries with similar circumstances. It's not like it's retaining any info while it's off, just your preference settings. So maybe the laser is SOOOO powerful to get those distant readings that it loves to eat batteries. My EoTech EOLAD laser runs for over 5 hrs. continuous on AA batteries (much cheaper). I'll have to have Leupold check it out. The glass quality on these are MUCH better than those on the Golden Ring Tactical Spotting scope that I also reviewed (it was like looking through vaseline). And the filters really do help! The laser seems to have a field of about 6" @ 50 yds. I tried to range a pinecone on the top of a tree and got readings to about 3" to either side of it before hitting infinity in the sky. I compared the reading by milling it with my mildot scope and was within 3 yds! The bino is a little bulky and heavy, but after all you are combining 2 tools in one. If you just need an LRF, then get a monocular style like the Leica 1200. I was able to hit a white house easily out to 900+ yds. Definitely would benefit from the use of a stable tripod.
