Here is the plot I made for our electric fencing. I measured all the distances with a 200' tape measure and marked trees that I could use as posts with orange tape as I went. Then, I overlaid this plan onto an existing map of the property that I have.
I forgot to put on the map that the size of the small field is 100'x50'. I sent this into Wellscroft and I'm waiting to hear back on a quote.
