Klein’s NCVT-3 combines a non-contact voltage tester and an LED flashlight. The tool registers high and low voltage (12 to 100V AC) with a 5-LED bar graph and an audible indicating power level. Sealed buttons and an O-ring on the battery cap make it dustproof and waterproof, and the durable casing can handle a drop of up to 6 1/2 feet, according to the maker. The tool has a CAT IV 1000V safety rating, an auto-power off, and a pocket clip.Price: $25 / COO: China /kleintools.com
