FEATURES |
| |
 Telescopic, compact, light-weight. |
| Light weight easy to sue and handy. |
| High-voltage detectable. The equipment, whether in stretched state is available for voltage detection in high-tension. |
| Easy to recognize indication. Intermittent lighting in red of a high intensity light emitting diode and intermittent audible sound of an electronic buzzer are easy recognizable at a full daylight, noisy location. |
| Water proof. The detecting head, being tightly enclosed, is free from any trouble due to dust, water. |

|
| The detector detects high and extra high voltage in AC lines. An elongate insulation rod permits checking of high tension circuits at a safe distance for voltage. Also it is telescopic compact, light-weight, easy to sue and handy. |
