This complete kit has everything you need to make a 40m fence around your pond. The fence gives animals a harmless but deterrent shock when they touch it, which should keep them away from your pond and fish.
10 insulated poles
80m total of fence (40 with 2 strands)
If you would like a longer fence then an extension kit is available. The set increases the fence length to 80m of two strands, just choose what you need from the drop-down menu.
