Triplett ET350 Non-Contact AC Voltage and Magnetic Field Detector

Perfect for finding that one dead bulb in your Christmas lights. I set it to minimum sensitivity and it didnt constantly go off.

The tester gives too many false positives but it never gives (so far) a false negative.

Well made unit but lights up before it gets near outlet and because of this it can not be trusted

is super sensitive, so you do not know which is the one that has power.

Im not sure I trust it. Others Ive seen electricians use dont have battery power or buttons to push. So its not as useful as Id hoped. Maybe with usage, Ill grow to trust it.

Easy to use

Does what it is supposed to do, detect magnetic field and current. On/off button will hopefully save battery as this isnt something you use everyday unless youre an electrician. Lets you know power is present. Really beats getting bit.

I like this tool but it is a little to sensitive for me it beeps when your 1 foot from hot wires so it sometimes is hard to tell if the wires your checking are hot. Also you have to hold the button Down the entire time you are using it. My old greenlee could be turned on and stuck in a receptacle and you could go turn the breaker off and listen for it to stop beeping.
