I don’t have any experience with the OnTrak products.
When I first started using GPS, I used a 500 on waas. This was many years ago, and waas may be more reliable now. Back then, I would still use the marker to make sure rows were straight. My 500 would say I was 0-1” offline of my A-B line. But A-B line would move 1’, then 2’ left, then eventually back to line up with marker, then wander to the right for a while.
I had trouble with RTK 2 years ago and ended up running waas on a field. I had trouble with row clutches starting and stopping either 3’ early or late, when I came to endrows. Made me a believer in RTK. Like they say, correction is addictive!
