I have electrical projects coming up, where I need to cut into an existing circuit. I can turn off the circuit breaker, but in the attic, there's no way to know for sure if the power is off on the cable I need to cut. My search for a reliable non-contact voltage detector brought me here.

I must have looked over all the different brands here on Amazon. Many reviewers, unhappy with their present purchase, referred to the Amprobe brand as what they went to, or were going to buy. This was what made me decide to buy this specific non-contact voltage probe.

The Pros:
+ The shipping is free.
+ Comes with 2 AAA alkaline batteries installed.
+ Nothing to turn on, since it's always on.
+ Very sensitive, even detecting which side of the cable is HOT!

The Cons:
- Not the lowest cost non-contact voltage probe, but sometimes it's better to pay more for quality.
- No audible, just a red flashing light when a voltage is detected. Having an audible wasn't important to me, but some may want an audible with the light.
- As with most non-contact voltage probes, this probe can't detect voltage presence if the cable is shielded.

Notes:
▪ When I first tried the probe, it didn't work! I checked the batteries & they were good? The problem was with the battery compartment top, which wasn't screwed on tight enough. Once I tightened it securely, the probe worked perfectly.

► Update - January 19, 2013
I used this nifty tool today to verify the cable I was going to cut was the correct one & to verify the power was turned off.

I'm upgrading my rating from 4 to 5, as this tool saved me time & works perfectly!

I've been a licensed electrician for over thirty years and love this tool. I use it just about everyday when checking for live circuits. With that said, never fully trust any tester and make sure you test it on a live circuit first. This tester will only read the live side of a romex cable, if you have it on the neutral side (white side) you will not get a reading and you might think the circuit is dead. This tester will not work on bx or amored cable. It is also wonderful for checking hot sides of switches or receptacles when troubleshooting a circuit. Be careful on three wire cables or exterior wire, you will get false readings...this tester blows away the klein tick tracer or the gb brand tick tracer. Although the amprobe does not make noise, (more battery life!) it is far more reliable then these other brand names.

I prefer a tester with light only, no audible and no switch. Always on does not seem to have adverse effect on battery life. Simple, and very dependable. A rapid, light swipe of the tip against my clothing will produce a brief flash from the static charge. That tells me both the diode and battery are good. And I want a less sensitive higher range. It's better, and here is why.
The voltage range is the sensitivity and that determines its application. The lower range (40/50v) is too sensitive and more limited. They will light when close to a group of wires and cannot discriminate among them even if just one is hot and they have been physically separated. I have a 40/600 volt that will light if it is placed against the plastic trim plate of a wall switch and that makes it almost useless beyond testing outlets. e.g.: 3 circuits in a box. You shut one off (you think). The tester can't tell you, it glows because its near the other 2 that are still hot.
It gets worse when you have 2 and 3 wire spliced circuit conductors increasing the field significantly.
This is where the Amprobe excels when you need more. It has a highest range of any N/C tester that I know of and can discriminate among wires that are just millimeters apart. You have to get close and that helps eliminate the error factor of a response from nearby conductors.
Now, there are 2 strong notes here.
First is that the spec listed on Amazon is 50/1000 volts because the individual package shows that. This is incorrect. The Mfg website lists this tester twice, under features it is 100/1000 and under specs its 110/1000.
I can tell you with certainty that in use this tester functions at the higher range and I have used them for many years. Fluke contacted and cannot explain the 3 discrepancies (????).
Final note.

Sometime times simple tools are the best. This tool travels in your pocket, is always ready, can be used in the noise, dirt and lack of good lighting in an industrial setting. Even the mechanics know how to use it! You can't get much better than that. Beats the daylights out of those new fangled ones that beep and blink and basically confuse the user. I highly recommend this detector for anybody who has to know if that 120-600 vac is lurking out there ready to bite 'em.

Probe is not extreamly sensitive nor is it low sensitive. It quite rugged as long as you don't break the tip. They last a couple years before the battery needs replacing. I'm a electrician for 25 years and this is my prefered volt probe. Like any tool, you need to now where it works good and it's limitations.

I love this hot stick. No on/off switch, no audible, high quality and durable. Doesn't start acting funny when batteries start getting low like all the other hot stick's I have used.
