The picture of the Voltage Detector is very misleading for anyone with limited knowledge...non-contact voltage detectors like the one pictured will NOT detect through metal, like the picture shows.
 
Voltage Detector

A voltage detector senses the presence of power inside cables and in some cases even inside walls. Before using it, test this battery-powered tool on a line you know to be live. If the end glows, the tester is functioning.

Continuity Tester

A continuity tester shows when there is a path for current flow. Use it to test a fuse, a switch, or the wiring in a lamp or light fixture. Use it only when the power is off. If the tester lights, there is a path for current flow.

Multitester

A multitester does the work of both a voltage tester and a continuity tester. Use it also to test low-voltage wiring such as a door chime. A tester with digital readout is easier to use than one with a meter.
