I started out with solar chargers, but they seem to wear out, They where not putting out the charge (after a year or two) that they did when we bought them.
We bought ours and put them up 2 years ago, we have already switched one pasture to the electric charger. and will be switching out the other pasture this year.
But I have an escape artist, that i am trying to keep in. He HATES being confined in fencing. Even our 2 acre pastures, he will try to escape out of. He will walk the fence line testing the charge with his nose and if there is a spot where the charge is weak, due to frayed fencing, he will just scoot under the rail......
