Looking at taking advantage of TAMS and upgrading sprayer here. Priced an amazone uf1501 with full gps control vs without gps and difference is small so will probably go the gps route. What are people’s opinion on going high tech. More things to go wrong would be a concern, but upgrading from a sprayer without rate controller I can see potential for a good bit of time saving being able to vary forward speed within a field. Like the amazone, but any other makes in particular I should compare and price? Has anyone experience of the Amatron 3 controller?
