I have the Newcon 3000 and have ranged consistant in all conditions to 1800 yds. on trees, rocks, cows, shrubs, etc. Over 2000yds on small targets in cloudy conditions is common, almost 100% on a tripod. Best in cloudy, good conditions was a sign at 4061 yds, 2 days in a row. Antelope on the flats at 1700 are tough, need a shrub or tree, but that's better than many RF's. Again, you pay for what you get.
