General Technologies Corp GTC CT8002 Cordless Circuit Tester, Black

I really like this tester but it doesnt replace a traditional test light. It is extremely sensitive and will alert even if there is only slight voltage present in the system. I like having this in my pocket for times when I need to do a quick test to see if there is power. It also helps that this is safe for computer circuits. I also love the Camco 63928 Quickee Circuit Tester because it uses an incandescent bulb (traditional test light). Sometimes it is necessary to place a small draw on your circuit and observe what happens next.

it worked like it should! this is what i needed for work! worked like a charm! would use it again! thanx

Very good

This tester I good for me when im bieng lazzy and dont feel like looking for a ground to conect my other end of my test light. As a professional car audio installer I love this test light when I test hids as I can check both power and ground when I touch the ground lead and test the power of the hid harness

This tester is a cheap and affordable way to check for voltage. You just have to make sure you use your body as a good ground and remember that. Doesnt take the place of the good multimeter but I use it daily for quickly checking fuses

very easy to use and has some nice features. id recomend this product to anyone looking for a nice hands or cord free unit for checking 12 volt utomotive

Very Hard to Find This Brand, But worth it

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.

Makes my job easier when checking fuses. Works great no problems yet

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.
