A great app and I think may still be free is iGIS. It allows you to import shapefiles (this is the file format that is used when someone gps's your course) into the program and displays them on google maps. It also allows you to add to and edit these files.
The iPad's gps is not accurate enough to map sprinkler and valve locations, but is very good for making IPM maps and location based notes.
