The Snap-on Cord‐Free Pocket Circuit Tester, No. EECT200, quickly detects DC voltage on automobiles, trucks and motorcycles ranging 3 to 24V DC. Users probe the wire or terminal and touch metal ground on the vehicle with their free hand, providing convenience and efficiency, according to the company. The EECT200 features an audible beep and bright white LED alert when any DC voltage is detected in the circuit. A pocket clip keeps the EECT200 secure and available with no power cord interference. The short stainless steel shank has an attached tip protector and a patented handle.
