Here's a few shots of my "Pencel" tester with NCV tester.
The probe retracts or comes out of the tip by twisting the collar, the extra Common lead has a gator clip that connects on the end. Everything is pretty well made and insulated really well. This model has been discontinued not sure if they make them anymore.
The tip lights green when voltage over 80 volts is absent, a Red led flashes in the presence of voltage over 80 volts, and it beeps to alert two ways that voltage is presant.
Rather handy devise and although it doesn't have a lighted display, it is easy to read, easy to handle nice to have one probe in each hand and still have a display to see in your hand.
The black on the screen bottom right is a shadow.
