The Extech DV23 Non-Contact Voltage detector is a new device for me. I have done a lot of electrical work in both new construction and rewiring of my house. I have always used a traditional tester, two wire ends into the outlet or one side of the tester on one wire and one on the other. With the Extech, it is possible to put the tester into one side of the outlet (one side of the two openings that you put a plug into) and determine which side is the hot wire and which is not. This can be particularly helpful when trying to rewire an area of the house which has older wiring which did not use black, red and white wiring.

Part of the trick to these types of testers, and being safe with them, is understanding how they work and how to use them. It also can give "false" readings if it's picking up a nearby wire, or even if there's some static electricity. Although it's listed as AC only, it will go off via static electricity from rubbing on your clothes, and it also went signaled when I brought it near a wire fed from a AD/DC wall wart. I think this is good from a "better safe than sorry" aspect. But, there's also situations where it won't go off but electricity is live.For instance, you can stick this into a wall socket, but it you put it in the neutral leg, it won't light up. You need to make sure you're putting it into the hot leg.

If you run (and you should run this along a wire, not just hold it up to it, as the wires can be twisted inside of a power cord) this along a live wire (or within a couple mm), or insert the end into the LIVE portion of a socket it both gives an audible continuous beep and lights up red. Works ONLY on AC current (like in your house) not on DC (battery run).This is very useful for when working with wiring as you can quickly determine what is live. Be aware when testing sockets however, to insert the end in EACH portion of the outlet. I have encountered outlets which were wired backwards so that if I had only tested the ground I would have been unaware that the outlet was live.This is so sensitive that it picks up static electricity as well.

A little more substantial in your hand than other detectors of the same type, the Extech is a super -sensitive voltage detector. So sensitive is it to induction voltage that sweeping your fingers across the tip during high static periods can cause the detector to chirp. Does this mean it gives a false-positive (or negative)? Not necessarily but it is something to be aware of when you put it to use. Follow the instructors to ‘calibrate’ your usage by touching a known-hot circuit before testing your target circuit.This tool will last a long time in your tool box as heavily built as it is. The only concern I have is that there is no on/off switch to isolate the AAA batteries.

This voltage detector is sensitive, but still useful.. Another reviewer reported theirs goes off when they touch the end of the detector, but mine does not. In my testing around the house, I mostly had to get the detector pretty close for it trigger. The only thing that seemed to set off the detector from a distance is one of our hanging ceiling lamps. The detector did not go off for any 5V USB cables, but it was triggered by my Macbook Pro laptop and the Magsafe charger, which should be outputting far less than 50V.The orange cap at the end twists off to reveal the battery compartment. The cap feels like it can be knocked loose pretty easy.This is a nice little tool to have around the house for electrical work,

I am remodeling and thought I could use this Extech DV23 voltage detector. This device works very well, indicating voltage without needing to actually touch a meter to a wire by emitting a buzzing sound. However, it also buzzed in short sounds when I was just sitting at my kitchen table. I do not know what it was detecting while I was just sitting at my kitchen table. I plan to use it to locate a wire behind the drywall that became lost during my last remodel a long time ago.

It works. Hold it close to a live wire and it lights up and beeps.It is very sensitive and seems to detect a static chargein the package it came with... very strange but I supposethis is a good reason to remove the batteries whenit isn't being used. The package has a battery storagearea and the unit comes with batteries so in this caseholding onto the plastic clamshell package might bea good idea.

Extech's DV23 Non-Contact Voltage Detector is easy to use and is something you should have in your home when doing any electrical work. It's important to note that it can detect nearby voltage, so just use caution and be sure to check carefully. It lights up and has an audible tone. Easy to see and hear. It does appear to be fairly sensitive, which is great, because you can never be too safe.
