Yeah going thru a bit of a learning curve with spraying with low volume lawn applications. I have relearn how to apply lawn application with these types of nozzles. I picked up some flood and flat fan nozzles at the tractor supply store, but they didn't have any AI nozzles. I get to play with them tomorrow. I have to start thinking like a boom sprayer nice even height very little movement type of technique. At some point I will be acquiring a gas motor and roller pump maybe even a diaphragm especially if I am not won over with these electric motors.. for lawn applications.
