Again, this (the original post) is NOT an AC tester, nor is it a proximity tester. It is a 12vdc tester that utilizes your body as a ground path rather than a wire with an alligator clip. The V trough is simply an added piece to easily center the wire so that the metal tip can more easily pierce the insulation; it can be removed.
