General Technologies Corp GTC CT8002 Cordless Circuit Tester, Black

This is certainly a nifty time saver, in that I dont have to hassle with a cord. Its affordable enough that everyone should have one in their tool box IMHO.

Just lik a normal test light that beeps. I suspect it uses your body for a ground connection. It is so weird and cool at the same time . You just poke poke beep beep instantly. Wireless amazing.

Useful tool, no need to clip on a ground wire just touch a bare body part or fastener. The point is a bit fat and clumsy, it could do with a real fine needle point or a proper wire gripper/piercer like a test probe to cleanly penetrate the wire insulation without damaging the wire.

looking good

This works great. No wires, just touch even painted metal in many cases for a ground. And is safe for computers.

Works fine. Not consistent. but it works. Actually Ive had it a year and it still work.

WHAT EVERY SPARKY NEEDS IN THEIR TOOLBOX.

GREAT product & price, works wonderful! Quality made.

Very Hard to Find This Brand, But worth it

I was skeptical about its ability to have a proper ground in order to work however this thing works fantastic. Id also recommend buying the adapters for checking the fuse panels.
