How accurate are your guess rows?
Can you repeat the lines?
Can you use them for spraying or side dressing?
Sure they are straight, You get relatively straight rows with any GPS signal. But WAAS WILL have drift and there are times when it will have significant jumps in a short period of time. I have been using GPS since 1996. I started with the old C-Band receivers. I have used Omnistar basic and then WAAS. I am now running RTK. There is a reason that the more accurate subscription services cost more. You get what you pay for. If they were no better than WAAS, no one would buy them. Yes, WAAS is accurate enough for many things, but row crop planting is not one of them. You can not plant with WAAS using a 12 row planter and follow it with an 8 row corn head. I have seen WAAS move 12 inches in less than 10 minutes. I have seen it make jumps as much as 30". You will see it also. What is the use of planting with auto steer if you can not use the lines later in the season.
