50-1000 VOLT DETECTOR

testing electricty

Seems to be almost the same as what I thought except these two new ones I bought was not exactly like the old one I had which was presented when I ordered it except these do look heavy duty and does have a light that goes on which is a big plus so yes, I do recommend these electrical power testers

This is my second GT-12 so far. I used to use the GT-11s and always hated the twist top to turn the tester on, which would eventually fall off. The addition of the push button makes this a much nicer tester. the only complaint i have about these is that the battery cover feels flimsy, you can push on it and feel it slide sideways. My previous GT-12 never lost the cover but it feels like a potential issue for those of us who use these often. The self check is nice however please remember too always test on a known live circuit first to make sure it works.

I needed to determine which of my black wires was line vs load and this made it fast and easy. It also kept me from a good jolt when I thought I had all the electricity turned off but forgot one of the three switches in this box was a three-way and apparently on two different breakers. With a gazillion wires in this box it was still easy to figure out which of my lines was load vs line. Very straightforward and exactly what I needed. It'll get a lot of use.

True and good product.

Works perfectly. Discovered "live" lines I thought was dead. Saves me a lot of up and downs from the attic to the circuit breaker. I use "face time on the iphone" to communicate with my helper to see what circuit breaker to turn off.

I am an electrician so I use this item every day. I do not like that it must be turned on to work. And it turns itself off, so I must be very careful when using it to determine if there is no voltage, or if the unit is just turned off. I previously used a fluke which is much more sensitive and a much better detector.Added:After using this item for a few months, I no longer trust it. Even when I make sure it is turned on, I can't depend on a reliable reading. It works sometimes and refuses to work 80 percent of the time. I am very sorry I bought two of these units because I just threw both of them into the trash. I won't even give them away because I am afraid someone will get injured or worse relying on them. They are worthless junk.I purchased another fluke.

I love this little tester. Its audible/silent and bright red color.I don't really use the silent feature but its nice to have it in certain situations. its got alot of features for a little tester. If it had the flashlight like the ideal brand, it would of gave it 5 out of 5. but its definetly something to have in your tool pouch.
