MX Rocket Type Continuity Tester with Battery (MX-866)

Checking continuity shouldn't require pulling out a full multimeter every time - this standalone tester handles exactly that single job, with its own internal battery and a simple probe-and-indicator design built into a rocket-shaped body that sits comfortably in one hand during repeated testing. Touch the two probes to either end of a wire, a fuse, a switch, or a connector, and it tells you immediately whether current can flow through, which is the fastest way to track down a broken wire, a blown fuse, or a switch that's failed open. It's the tool to keep in a toolbox specifically for this one recurring diagnostic task, faster to reach for and simpler to use than digging out and setting up a full multimeter just to check if a circuit is complete.
