1. WIDE MEASURING RANGE. Designed for low impedance and standard duty fence controllers. 6 neon lights indicate voltage from 2kV to 12kV. Higher measuring range compared to standard models. Does not require batteries and functions without external power.2. VERSATILE APPLICATION. Measures voltage on metal wires, ropes, tapes, and fencing lines. Tests fence lines, ground systems, hookup wires, and fence components. Suitable for use in farms, gardens, and livestock enclosures for sheep, pets, horses, and other animals.3. EASY TO USE. Simply hold the top probe to the fence and insert the ground probe into the soil to obtain a voltage reading.Color: Blue & Black Material: Plastic Package Contents: 1 x Fence Voltage Testing Tool Note: Other items not included. Due to lighting effects and monitor settings, the actual color may vary slightly from the image. Measurement error allowance is +/- 1-3 cm.
