i would keep that at 0 if youve set the tractor up correctly
that will give every implement and offset

there is seperate offsets for implements

OK tractor definitely not set up yet but mine had a figure in the box already and was almost doubling itself then missing the same amount. the antenna is mag mounted to a bolt on the roof which may not be central. Is that not a way of offsetting the antenna to centre iyswim? Seemed to keep the drill at the right width. Not auto steering yet of course.
Been struggling with connections till yesterday first field without loosing signal from end to end.

yes it works just watch that that offset doesnt transfer to each implement
to set up my antenna on tractor i set a stake or marker on a flatish field and set a AB line past the marker about a meter away
stop alongside marker and measure to wheel then go forward 40-50 meters and turn round and come back same AB line and measure to the wheel again(on opposite side )
adjust the antenna ,keep doing it until you get same measurement both ways
then get a sharpy and mark the roof so if a branch moves antenna you can put back easy

Is that 10-30cm error just on the ground or shown on the screen too?

Screen too, took a picture not that it shows much.

I’ll have a play when I go rolling as a missed bit isnt as much of an issue

Antenna higgt set riggt

That’s one thing I haven’t checked, will it affect the movement that much?

Yes
The more time you spend with a tape measure the better the results

WAS not centered correctly would be my first thought if it is consistently driving off to one side of the line.

If it was something like a an offset not right then it should at least appear to be driving to the line on the screen.

Set a friend up with an AgOpenGPS mapping system to map his field boundaries and accurately place SFI options.

Using a VRS RTK signal.

I want to do something like this with a hand held staff, so I can walk and map field drains.

Plug f9p into android phone or tablet and use a mobile app, also an option. I'd use aog tho
