Anyone use GPS app for spraying/planting/spreading?

[Doc G]

I use a Field Navigator app with a Garmin Glo antennae for better accuracy.
Works well enough to spray preplant on fields and spread course fertilizer.

This is super helpful thanks. I was pulling the fertilizer buggy this morning and thinking that that is one application where +/- 3 to 4 feet is really no big deal when the spread is 20 ft and there's overlap anyway. Really hard to see previous tracks that far apart.
