Voltage Testers

Proximity testers, voltage indicators and fault finders are the three general types of electric fences voltage testers. A proximity tester is a small audible device used to warn when a fence is live, it often takes the form of a key fob, sometimes carried by ramblers as a safety precaution.
Voltage indicator lights clip on an electric fence wire, when the fence system is not running at the correct voltage they change colour or flash. Fault finders are used to diagnose where a power problem is occurring in a fence system.
