About 30 mins into the detecting I noticed that the tractor kept coming very close, then stopping until we moved on a bit, then starting up again. I know most of the drivers, so I went over to have a chat when it came close and had stopped again.
The driver was all very apologetic and said that there was a problem with the GPS as it had gone all wonky. He asked me to switch the Deus off, so I did and the GPS then worked fine. We experimented a bit more with the Deus controls and it seems that within 20m the signal off the Deus scrambles the GPS signal! This resulted in the GPS wanting to get nearer to the Deus signal, the driver then had to manually steer away from us and that was a big problem to us!
We had to pack up and move to another field and all was ok but I thought I would mention this as the drivers tend to not have their hands on the steering wheels and leave it all to the GPS signal, but if it comes within 20m of a Deus it will go off track towards the Deus.
So, don't get squashed and beware of tractors with GPS, Liam
