Anyone got one or used one?
Looking at getting one for use on potato planter for mainly mapping out the boundary and giving an internal boundary line to see when to lift out/drop in.
Any comments appreciated , thanks

It would be running on EGNOS with decent pass-to-pass accuracy but poor absolute accuracy. Meaning a big error at the headland (long time between mapping the headland/internal boundary and the actual work). How accurate should it be?

Ive no idea on the accuracy. I was just wanting to use it for the field acreage and to mark an internal boundary. In some cases we could be in the same field for a couple of days more if the weather holds things up, will this effect the internal boundary line? I wouldn't want it drifting by a huge amount or it becomes pointless.

I'm not sure about the correct figure, certainly depends on the quoted confidence level but here is an example answer from google:

If the device supports a (2D) reference point, you could calibrate the receiver every 15 minutes or so to reach the pass-to-pass accuracy (of the order of 30 cm).
