Our orchards and vineyards have fences like that or 10 foot deer fencing around them around here. It's the only way.Yeah, I kinda figured that electric fence in your pictures would not keep out the deer we have. I know a guy who was growing grapes, and the deer would come and eat everything. Long story short, he ended up installing an 8-foot-high fence and added that angled wire top before he finally beat the deer. HIs little vineyard looks like a prison yard, but at least he now grows grapes and is able to harvest them.
His fencing looks something like this Google picture...
