This device, commonly known as a "wiggy," is a coil / solenoid device, old technology, which uses electrical current to move the red bar indicating about how many volts, whether DC or AC current. It also indicates whether a lead/electrode/wire has voltage by the use of the positive/red lead, a red led comes on if voltage is present. It also indicates continuity with the use of the two leads, which is very useful. This may sound like what many other multi-meters and devices do, but the difference is, this old technology is absolutely dependable. I also have many of the currently made high tech multi-meters and use them a lot, but the wiggy always comes out first for dependable trustworthy "life-depends-on-it" information quickly. When this is connected to wires with sufficient voltage, the red bar moves to indicate about how many volts are present, and it makes a sound, and vibrates, all of which instantly tell you the whether the lead is hot, and about how much voltage is present. When I am trouble shooting, this is the instrument I use. It quickly and accurately lets me know which circuit breaker is on/functioning and whether it has the full voltage AND current. This is where it shines up against the high tech modern devices. The latest multi-meters will give false voltage readings, showing voltage where there is none. This is due to impedance and capistance induced voltage which new solid state devices will show but the old tech solonoid wiggy does not. It can be very frustrating trying to correct a problem which does not exist, which will show to exist on new high impedance multimeter devices. I own and use multimeters made by Fluke, unitech, Klein and others which just are not as dependable and will show false voltages. This device is the one I reach for every time doing a troubleshooting job. They are rugged and dependable. But they are not loss nor theft proof, and thus the reason I just purchased this one, my 4th. J WRead full review

This device is the first thing used in almost every job I do when working with live wires, and I work almost all of mine hot as I am a trouble shooter. One precautionary note on this device. The leads of this wiggy are connected togather where they plug into the top of the device. This is not made well and they come unplugged easily which is an incovenience plus have to be watched out for or I will not get a reading when it should read if I do not notice the leads have came out of the device. Plus this is a possible electrical hazard if working with high voltage DC as if it is not in very tight it could be possible to get an arc there. In high voltage DC this could cause the device to explode. I will not use it on high voltage DC at all because of this. But as to the main function of this device, to determine whether there is voltage and approximately how much. Crucial to trouble shooting working with hot wires, it is critical to know whether there really is voltage or or not. Unfortunately, most of the modern multi-testers use very little electricity to run there fore not placing any additional load on the lines. This is very useful for electronic devices but in the relm of 120VAC to 600vac and DC they give false readings saying there is voltage where there is none. This wiggy is absolutely correct on whether the voltage is real or false/ghost voltage avoiding that error. I must know whether the voltage is present or not. This device uses a simple solenoid with a spring attached to the sliding marker showing close to the amount of voltage present and whether it is ac or dc. It buzzes when it is connected to voltage and shows approximately how much. If it is necessary to know exactly how much voltage I use a multitester after using the wiggy to determine if it is real voltage for that quantity. But for most testing in residential and commercial use I do not need to know the exact amount. This can be read to within a few volts of the amount of power which is usually all I need. Another very useful function of this device is showing continuity. Touch each end of the probes to where you need the information and it will make a low buzz to led you know that there is continuity. If none it does not buzz. I have owned several of these and will never be without one. J WRead full review

I've had one of the old '076 wiggies for ages. The continuity tester is handy if for no other reason than to test the leads before you go for the hot stuff. But the years have caught up with mine. The leads are iffy, the batteries are just about dead. So I went looking for some new leads and found this newer model for about the same money. With new leads. And fresh batteries. Hot deal. Just a fresher version of my old unit. And really, one "false-cold" mistake can be embarrassing. What a deal. Factory-sealed package, shipped in a protective envelope, arriving quite quickly.

This tool is a good tool to verify voltage or lack thereof on any circuit under 600 volts before touching any possibly energized parts. It also reads continuity for tasting fuses, switches, etc. One would use this tester with a digital meter to measure actual values on the circuit under test. The Ideal tester will eliminate stray voltage readings while using it to verify presence of voltage.

• very nice, solidly constructed unit, excellent deal at the reduced price • safety shrouds on the test leads are spring loaded and will 'twist lock open' leaving approximately ⅛" exposed when desired • if you haven't had any experience with one like this it may initially come across as a bit confusing, however, the instruction manual is very well laid out; - at the lowest level to medium voltage range only the LED's at very bottom will respond; - as the voltage approaches 120v (but less than) the middle neon also responds; once you reach 120v and above then you also have the solenoid portion (this applies to both AC & DC), in conjunction with vibration and audible; - Cautionary note - the continuity LED also serves as low voltage DC notification - in order to differentiate and verify between continuity or DC simply reverse the leads, if the DC negative LED lights then you indeed have a DC voltage, if it does not then there is simple continuity.Read full review
