I have a Section A houdini that keeps trashing everything.
I am currently installing Hotecote which is by horse rail - they have a website which shows the product.
I have one paddock done and it is not yet electrified and the section A has not yet gone through it.
They recommend a mains unit for it because you can electrify all 4/5 strands
As I said I am installing it (by myself) and it is easy enough to do and handle.
If you PM me your email address I can send some photos if you want - obviously its not been up for long but so far so good - section A would have been through the usual tape/rope even with it electrified by battery unit at least three times a day so its promising as its not even electrified yet
