Free? GPS spray tracker. https://play.google.com/store/apps/details?id=lt.noframe.farmisfieldnavigator.free might suit you.... I’m looking for a reasonable priced unit with good accuracy.
I’m using an Agricision OnTrak with my iPad and it works very well. It’s about cheapest system I could find that paints a picture of ground covered.Does anyone use a gps that not only shows speed but also shows ground covered when spraying fields and pastures? I’m looking for a reasonable priced unit with good accuracy.
That looks very cool. Far more advanced and cheaper than some stuff we use in airplanes for surveying! (Mind you we aren’t looking for 20cm accuracy in those specific applications!)
