Electric fence revisited

This is what I’m trying to protect this year. Nobel and Black Beauty Muscadine remain. Plus I want to figure it out this year because next year I will have a much larger crop.

I’ve added another wire and more post to make sure the distance between the wires are closer no gaps. First wire is 3″ from the ground. Second wire is about 4-5″ above that. Third wire 4-5″ above the second and the top wire is about the same 4-5″ above the third. I’m hoping this stops them.
