Re: leoupould rx4
Mine works great out to 600, even in bright sunlight. I have had mine for about 2 months now and have used it side by side with the Swarovski. It will not range as far as the Swaro and it's optics are not as good, but if you are looking for 600 yards or under and would like an inclinometer to boot- you will be happy.
I have ranged high reflective targets beyond 1k several times.
