Southwire Tester NCVD - Detects AC Voltage with Audible & Visual Alerts - Auto Power Off - Dual Flashlights - CAT IV 600V Safety Rating

It's a tic tracer and works. No problems, good price, good quality.

I looked at several and watched a lot of reviews. This is the best bang for your buck and works great. Fits inside the front of a GFCI too. Very happy with this hot stick.

Great unit. 5 stars. Very sensitive. It can give some short false postives but I am totally fine with that. I would rather have little short beeps than a false negative. (A false negative means there is no beep when there is voltage) If given the choice between really sensitive and not sensitive enough, I want really sensitive every time. The false postives are short little chirps and the real positives are a long string of beeps and lights flashing red. If you tap the tip on certain things you can force a very short false positive. (just like my beloved old unit) With this Southwire tester I can touch it to light switches and get an alarm. (with the cover on) Of course be careful and always test the wire before you work but I like the ability to sense from a distance too. Also test the unit to make sure it is working each time you use it. Before I bought this, I bought another brand, which I perceived as a top brand, and I paid more money but it was nowhere near sensitive enough. This Southwire unit is perfect. The price is amazing. I have a large DC adapter with a flat 3 wire AC wire feeding it. It does not beep on one side but does in the middle or the other side. I can't even say it is overly sensitive. It is just about perfect. If I had a potentiometer to set the sensitivity, I would lock it in place right where it is at. I lost my old unit that I had for many years. After buying another product that didn't work for me, I found some YouTube videos with reviews and decided this was a good choice. The light is just ok. It is powered by 2xAA batteries and has an LED. It is bright enough that you don't want it in your eyes. (you will see spots, don't ask me how I know this) The light is adequate for looking at wires in a box. That is just a bonus for me though. I have lots of bright flashlights. To power on the light, hold the red button on the end. To power on the unit for detecting voltage, hold the red button near the tip for a second or so. The tip will glow green while it is on. It flashes red and beeps when voltage is detected. (fairly loud) It can be turned off by single pressing the power button or you can let it time out. (a few minutes) It makes a different beeping sound when it turns off either way. So far I only wish that I had bought two of these. (keep one in a known safe place and use the other one) I believe I like it better than the one I lost.

As a new construction/industrial electrician, I have a Klein Tools non-contact voltage tester that detects low and high voltage and use it for most of my work. I bought the South Wire non-contact voltage tester which only detects high voltage (anything 120 volts and up to 600 volts) for a back up. But it's simplicity makes it my "go to" voltage detector most of the time. And for the price, you can't beat it honestly. It is pretty well made too and easier to change the batteries as well. Very good product over all. Safe and simple to use.

I like it a lot better than the one I had already. It's simple and clear. Just an on/off switch; the tip lights green when it's on/red when it senses voltage. None of the 47 bells and whistles I don't need or want. It could be better in 2 ways, for my money. I wish it was bright orange or yellow; brown and black is practically camouflaged. And the flashlight should have an on/off switch instead of a momentary switch.

While this is an Electricians friend, it should be yours too. This detects voltage (power) in a wire without you having to use a volt meter. You can easily find if your extension cord is damaged internally by following the outside of the cord until the light goes off. Check plugs easily to detect if they are working or wired correctly (the smaller line is always the hot side). Electricity is dangerous and if you're not sure about something, be smart and call a qualified Electrician.

Es perfecto y no se corre ningún riesgo de ser alcanzado por la electricidad. Como usuario uno queda protegido y aislado de la corriente alterna.

I feel safe having this handy tool. That is what its all about. No guess work if you have a hot wire. This tester is what electricians use and if its good for them then its good for me. It works on A/C wire 110v and 240v. I think it can handle up to 600 volts. When you use this tool, it beeps letting you know the circuit is hot. If there is no beeping then it is not energized. Be sure to move the voltage detector all the way around the wire because you might miss detecting the hots.

Lo compré para el trabajo de mi esposo y me dice que lo lleva a todos lados. Él es ingeniero de Servicio y le da un buen uso, siempre lo carga y dice que es de los mejores.

Seems to do the job..no issues..changed a two and a 3 pole smart switch. Definitely helped to have it..!!!

Excelente sensibilidad para detectar voltaje y muy facil de usar, en adición la lampara que posee es de gran utilidad. excelente producto, presenta un apariencia muy ruda y ya teniendola en las manos, efectivamente esta muy bien construida.

I can't believe how long I have gone without have one of these in my toolkit. This was the cheapest I could find and that how I like them. Clear loud beeps and LEDs make it easy not to get electrocuted.

Hasta el momento, no hay ningún inconveniente en cuestión de su desempeño, ya con más de 2 meses de uso continuo y algunas caídas, (no más de 2mts) sigue en buenas condiciones de funcionamiento. Recomendable, buena relación calidad - precio.
