I got a puck and Ag Express harness last year, but never ran it.  The Precision guy at Heartland Ag told me that he had heard of Viper issues, when using FieldView drive.  I hooked it up to my Viper Pro and ran it over my preplant acres.  I always look at my coverage map before leaving the field and never saw any issues.  Maybe I am a lucky one.  Does the info get sent to a Cloud for mr to see on my Climate account?
