Wide Application: Can quantify voltage on various metals, polyethylene wires, ropes and polyethylene tapes as well as fence wires, power supplies, grounding systems, connecting wires and fence components. Helps to find fence wire faults Measuring Range: The electric fence wire tester measures voltages in the range of 2kv -12kv, neon display, and the service life of the ordinary strobe light is up to 20,000 times. No need to add batteries 8 Indicator Lights: The fence voltage tester has 8 neon indicator lights corresponding to the detected voltage, which are easy to observe and use to find faults in the fence wire. You can keep 1 for regular fence wire maintenance because it is designed for low impedance and standard working fence controllers Simple to Use: Just embed the copper probe into the ground and let the top hook touch the wire or tape. It will display the reading range of the voltage. The reading is different from the LED. The small design allows you to put it in your pants and it will not take up much space Humanized Design: The wave pattern on the side is comfortable to hold. The frosted shell is smooth and comfortable and will not hurt your fingers. Matte finish creates no glare. Rugged ABS shell can withstand cold climates but is not waterproof
