I have an elite 1500 and have had good luck with it. I had a nikon 600 before it. The elite 1500 is 3 times more powerful. I have picked up horse trailers at over 1600 yards, moving cars at 1400. The farthest I have picked up game is elk at around 930. Antelope seem to be the hardest on any rangefinder, I have picked them up over seven hundred yards away. I have also not been able to pick up antelope that I though were under 500 yards.
I really got no complaints at all with my 1500. I have ranged and killed 3 elk, 2 deer, and 2 antelope from 228-450 yards since i started using it two years ago. It is a little bulky but I don't mind as the case has been used as a rear rest for my longer shots in the field.
I may want to upgrade when my custom rifle
is done and my range extends. But mine works consistently enough for game out to 800 yards or so. Which is farther than I am comfortable shooting consistently in any wind.
