Not sure if anyone interested but I bought a Amazone Profis Hydro spreader that came with an Amatron 3 control box, I took a punt and bought an off the shelf (Amazon for £200) GPS Garmin receiver which seems extremely accurate (20 to 30cm?) using SBAS for DGPS which is good enough gor spreading, cultivating etc and can take advantage of the spreader auto on/off function and area worked etc. now it’s got a GPS source.Not sure what others are using but this is a cheap and simple solution.
