Used them, won't own one. The issue is that to get a range and make you feel awesome they use a beam deliverance that is the size of a simi which is great till you try to range a game animal in natural terrain and you start getting ranges that are different each time or you shoot to the range and you bullet falls way short or goes way over. They work well in bow range, that is all my buddy trust his, beyond that we use my Leica 1200 or 1600.
I own a pair and love them for their consistency and accuracy when compared to professional surveying rangefinders, as I had a chance to do.
I don't know what "Feenix" was ranging or why he did not get good results but mine do great on game. 770 to 805 meters was my furthest on Mule Deer and it worked very well on each animal in the herd. They displayed my hold over in Mils (for my Mil Dot reticle) for each animal based on my 180 gr. .300 Win. mag. cartridge. You can also set it to read in MOA. The herd was above me at maybe 20 deg. and if there was any needed hold-under I was confident the binos would subtract it to the calculated hold display.
For the money they are THE best binocular/LRF on the market. And they carry a lifetime guarantee.
