This was on the monitor, havent checked it with a tape yet. But when we were doing the calibrations, the one where you mark the center of the drawbar then turn around, it was dead on.

RTX is not RTK, Ill agree on that, but it doesnt have the cost either. I may upgrade someday, my system is unlocked to RTK, but for right now, the price and the accuracy Ive seen so far, Im not sure its really worth it for what I do.
