From the Manufacturer
The Gardner Bender Heavy-Duty Solenoid Voltage Detector is so tough and dependable that it's called the electrician's workhorse. The unit is designed to test polarity and 120-600 volts AC/DC. It features dual voltage indication through solenoid vibration sensing and electronic neon. The retractable, spring-loaded prod shrouds protect metal tips, yet lock back out of the way for easy use. The built-in sleeves in the case hold prods for one-hand operation and store them for handy carrying in a pocket or pouch. The detector comes with a one-year warranty to ensure your confidence in its effectiveness and dependability. Gardner Bender has 50 years of experience making professional electrical tools and supplies of consistently superior quality, so you can count on high-performance products at a fair price.
