Redman is in NZ, where electrical fencing is used widely and in very long fences. Their experience with the fencing is excellent as is the equipment, which was first used extensively there and in Australia, if I recall correctly.
He's right, a good electrical connection is founded with a GREAT grounding technique (earthing). Given that, and a modern, high impedance fence charger and a great fence tester as we are discussing, you are all set.
TomSeller, when yours arrives, let us know if you think it is worth it...wait until you have a REAL problem with your fence...did you find it faster than your present method? I'm betting you will become a believer!
