I had never seen a Newcon rangefinder before, but I currently run the Burris B-1500 and after looking at the pics from the previous thread that was posted, I am 100% positive Newcon is building this unit for Burris. If I were to lay mine side-by-side with the Newcon, the only difference is the logo!!!! I have had good luck with mine, and have ranged good objects clear out to between 1600-1700 yds.
Take a look at the pic on Burris' website
I'm sure the Newcon LRB 3000 would be awesome.
