Review: Safe, easy to use and reliable - Get one. if you are an amateur, sorting out sockets and ceiling roses and switches in your house.. or even checking continuity in a broken electronic device to rule out if its a connection issue. many of us, myself included.. are NOT electricians who are looking to buy one of these. if you are then chances are you have one or two sets of the very expensive ones. they would be more durable and trade rated or whatever. even though this is more than capable for trade use. for the average diy person the price is considerably more expensive than one of those little screwdrivers that light up, but that is probably what you have been using before looking at one of these right? bin them. they are fine for messing about with 12v circuits or whatever. but not 240v!! this martindale device ensures that its made out of the right materials so that you cant get zapped through the plastic housing. it beeps and shows the right led when touching the probes together. you know its working then and the batteries are good. you can buy an additional proving device to ensure its reading the correct voltage before attempting to mess with any connections, get it if you are in doubt and value your life! but for an average diy person. who has the power shut off and nobody will accidentally turn it back on, this device is perfect. i tested it on a live socket. it gives this angry beep sound. a bit different to the standard beep for continuity testing. and showed the right voltage (240v). all you do is connect the yellow device end to live and itl read the voltage to tell you its live. its a real time and life saver. just stick it in your back of electrical stuff, and whenever you are going to change some switches or sockets or whatever.. use this device on it. turn off the power. use this device again. and if you want.. use it again! just to be sure! its a protective shield between you and a nasty shock or instant death! a great thing to pair with this is a socket tester. its a little plug that will show you if the live and neutral are correct. if the socket works and is live and also has an rcd function to trip the circuit. they arent expensive but go well with this. i plug it in, if it lights up... socket is live. so i test with the probes then to see if the probes really are working. i also check then when all installed. sockets are easy peasy for an electrician. they install so many. for a diy person u probably only change a socket once or twice and mostly for cosmetic reasons! but get this to be safe. and also to enjoy working on things at home. if you have no idea what im talking about with continuity or 240v and 12v etc.. then best to not buy this and to call an electrician haha that being said. still buy one of those socket tester plugs. check all of ur sockets at home and check that the trip switch activates. thats a good one to get for anyone
Review: Must have product if you're near electric - Perfect, never get an electric shock again. Very easily used

## Questions & Answers

**Q: Hello, can the vt12 be used for proving a circuit dead ? 
if not why not ? thanks**
A: The VT12 can be used for proving dead, as long as it's being used with the correct proving unit that tests the entire range. The Martindale PD690S is the recommended companion unit.

A dedicated voltage indicator for proving dead (such as the Martindale VI-13800) will offer a higher level of safety & confidence as they're designed with minimal failure points.

**Q: How long is the lead?**
A: About a metre

**Q: Can this do single lead voltage detection?**
A: Hello and thank you for the interest. Yes, the VT12 (as well as the VT25 and VT28) does single-pole voltage detection.  This feature is designed to detect the presence of a voltage but it's not meant for proving a circuit dead.

**Q: can I use this to check if my Earthing bed-sheet is actually receiving electrons from my connection!?**
A: Hello and thank you for the question. The Martindale VT12 is a tool that indicates the presence of voltage or circuit continuity, but hasn't been tested for your specific application in particular.
