Cons: Flashlight is almost worthless(but who really is buying this for the flashlight?)
Use at work to trace wires, spot check for voltage(yes i double check with a meter), and to differentiate quickly between different voltages in large runs of wire all ran together. This tool can be very effective at "sniffing out" different voltages if you learn how to use it correctly. It is very sensitive so sometimes covering the end with your finger will help you get more accurate results. Also isolating the wires your testing best you can helps a lot. I use this to troubleshoot lighting/ballast problems at work and it saves me quite a bit of time. The wire terminations for the ballasts and the lights are very hard to get to in some cases and being able to locate/differentiate voltages in wires going from the ballast to the light cuts a lot of troubleshooting time out.
When i say differentiate between voltages i mean in a general sense. For instance 1bar= 24v-48v, 2bars= 120v, 3-4bars= 220v-277v, 5bars= anything above 300v. This is scale is an average indication based on how i use the tool and is not indicative of what you should expect. You should always verify with a multi meter and isolate power before performing work.
This is perfect for what I need. It's very sensitive. It detects the presence of voltage very easily and it can do so from a decent distance. This is something that I can rely my life on to double check if there's current flowing through on AC CIRCUITS ONLY. No NCVT will work on DC current. In short, this is a great tool for homeowners and DIY'ers who only need to know if it's hot or not.
I had a klein NCVT-1 that I bought from the homeless despot and it works and it does what it's supposed to however it is useless to me. It only detects voltage when it is actually in contact with the circuit or it is right next to the hot side of a cable. It must be on the hot side which is a deal breaker for me. I cannot depend my life on that when it only detects the voltage 50 percent of the time in actual use. As a homeowner and DIY'er, the NCVT-1 is almost useless however to a professional, they will likely find great utility in being able to know which side of the wire is hot or not.
As I shopped for the right tester the biggest selling model was a fraction of the price of this one from Klein Tools and I’m sure it would have worked just fine. But working with electricity isn’t the time nor the place to go low budget. I was attracted to this one primarily by the five LED’s that not only show you the presence of voltage but gives you an idea of proximity and strength, that plus it has a warning beeper for good measure. It is a non-contact type, which seems to be what the majority of them are. I wasn’t sure why that was important until I realized that it will work through wiring insulation, cable caps and with those switches where the wire is pushed into a hole in the back of the switch rather than attached to an exposed terminal. It makes a lot of sense you need a tester that doesn’t actually have to touch a bare wire to warn you of the presence of voltage.
This model includes a built-in LED flashlight, partially contributing to its higher cost. The very last thing I need in my house is another flashlight and that almost turned me off to paying extra for it. Then I got to thinking about those real-life scenarios in which I’m working deep inside a terminal box and guess what, I had to turn the circuit breaker off which means none of the room lights around me work. Of course I need a flashlight and I only have two hands, so having the flashlight built into the end of the same tool I’m using to check for voltage isn’t just a convenience, it’s an important design feature.
I’ve never owned anything from Klein Tools but I’ve always heard that they are one of the best brands. Did you know they were founded in 1857? That’s 22 years before Edison invented the light bulb.
I'm surprise and disappointed that a company with such a highly regarded reputation is so lacking in a how-to-use owner’s manual. They show an illustration of the switch locations and how to replace the batteries but that's about it. I guess they assume someone buying this knows all about using it but they're wrong. They need to include a detailed tutorial on the proper use of what to do and what not to do in typical DYI use of a non-contact voltage detector.
The tester, which combines the best features of the Klein NCVT-1 and NCVT-2 and adds more is surprisingly rugged feeling, it may be the first one I’ve owned but I’ve got a feeling it’s going to be the last one as well.

Al no requerir contacto directo con el cobre, no es necesario pelar el conductor, pues es suficiente con ponerlo cerca del mismo por encima del aislante termoplástico.
Basta con acercar el probador de voltaje al conductor y si éste es fase, entonces se prenden los leds rojos y emite sonido. Si se trata de neutro, entonces prenden nada más los leds amarillos, indicando que no hay tensión.
Incluso, si lo que quieres es probar un contacto, no necesitas desmontar la placa, sino que lo pegas del lado de la ranura pequeña (donde se conecta la fase) y se deben prender los leds y debe sonar; en cambio, cuando lo pegas del lado de la ranura grande (donde se conecta el neutro) sólo se prenden los leds amarillos. Evidentemente, si lo acercas al contacto y no sucede algo de lo anterior, entonces significa que no está bien conectado.
Su tamaño es el de una pluma relativamente gruesa, a mi parecer es cómodo y poco estorboso. La pequeña luz led que trae integrada es de mucho apoyo, pero no esperen que alumbre un cuarto, más bien es para alumbrar directamente una conexión dentro de la caja, centro de carga, etc.
Aunque el NCVT-3 me parece mejor opción que el probador de voltaje convencional (el que es un desarmador y cuando toca el conductor prende una mini luz) y se supone que lo sustituye, yo lo uso en conjunto con éste, pues siempre me parece mejor tener dos opciones distintas para corroborar si un conductor tiene voltaje o no.
Aunque es cuestión de gustos y de forma de trabajar de cada quien, sólo recuerden que los probadores de voltaje que no requieren contacto tienen 99% de efectividad, es decir, pueden fallar en algunas ocasiones. Hay muchos vídeos en YouTube en donde hacen pruebas y algunos conductores de fase no los reconocen, aunque francamente son muy pocos casos.
Tip: si no les urge, esperan a comprarlo en las ofertas de Prime Day, porque sale más barato hasta que en las ferreterías del Centro de la CDMX.
En general es un probador de voltaje fácil de utilizar y que detecta rápidamente los cables con electricidad, lo único negativo que le puedo encontrar es que lo considero caro para sus funciones, y aunque cuenta con una lampara potente y un indicador de electricidad en forma de rayitas que se iluminan más y más conforme se acerca a un cable con electricidad, me hubiese gustado que también diera una lectura de voltaje como los voltimetros por medio de una pantalla, esto lo menciono porque vi un modelo de la misma marca pero con medidor de temperatura (tiene una pantalla), y veo más razonable el precio del otro modelo de la misma marca por las funciones que presenta al de este.
