3/4 to 20 inches is not a good enough answer for me when I am strip tilling and I ask how accurate is your service. is it 3/4 or is it 20? when they say 1-30 minute convergence times, is it 1 or is it 30? I have been there and done that. fast convergence requires an rtk unlock anyhow. if your already there and want true rtk (sub inch accuracy and unnoticeable convergence) why not pay half the rtx subscription price to get it?
RTX used to claim 2 inch accuracy on the trimble website, not sure if it got better or not or they just reworded it because they thought .75 to 20 inches sounded better.
I am not knocking it. its a simple system for pretty good not repeatable accuracy. unfortunately the convenience is expensive but that's how it is.
