The Martindale VT4 is a dual-sensitivity voltage indicator that alerts the user to the presence of voltage.
Suitable for all electrical tool kits, this low-cost detector detects AC voltage from 50V to 1000V or an alternate mode can be selected which has range of 12V to 50V. When voltage is found, the VT4 will alert the user by shining a bright LED indicator and will emit a buzzing tone.
A useful torch is also integrated into the tester to aid with seeing what you're doing in poor lighting conditions.
