Enter my latest purchase: this shiny new voltage tester, ready to save the day. After an unceremonious unboxing, I got down to business. I tested it on a few known live cables – to my delight, it beeped and blinked with the enthusiasm of a gadget that's doing exactly what it was made for. Now, let's be real – cutting into cables isn't exactly my idea of a fun time, but armed with my new voltage tester, I felt like an electrician superhero. I zapped around, testing here and snipping there, all with the grace of someone who was definitely, probably, hopefully doing it right. Long story short, I completed my job without becoming a human lightning bolt, which I consider a resounding success (and my house hasn't burned down either due to my wiring - calm down reader, the brother-in-law is a qualified electrician and signed it off afterwards). In conclusion, if you're in the market for a voltage tester that's reliable, easy to use, and a potential lifesaver (literally), this is the one for you. It did its job perfectly, and I lived to tell the tale – what more could you ask for? Review: Safe and simple to use. - Easy to read and a high accuracy of detection. With a built in torch to assist in dark areas during power outages. The unit comes with clear instructions and the build quality is excellent. A great tool that could save you from a nasty shock. ## Features - Non Contact: Just place the NCV tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Tests. Handy circuit tester for electricians, and homeowners. - Safety First: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green, red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected. - Dual Range: Only detects AC voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph. - Security Level: IEC-rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double-insulated. High Voltage Alert to warn you of voltage above 70V, the screen turn red, and the electric shock warning symbol is displayed on the screen. - Compact Size: Bright LED flashlight and backlit for work in dim areas; Auto Power Off after 5 minutes without operation or no signal detection; pen hook allows you to carry it in your shirt pocket.

The meter would register about "1 line high" near the wires BUT it would also cause the meter to blink the same on places on the wall where there was absolutely no elec wires! I did the test both using the regular setting and also the Supper Sensitive setting. So MAYBE it MIGHT give you some idea where the wires are, but doubtful since there are to many false readings to be sure. That said, this meter works great if you are taking readings without sheetrock blocking it. **Q: would you recommend this over other models and why? what do you NOT like about it? how accurate is it?** A: I like that it is louder than others, equally easy to use, and the price was good **Q: I believe a wire that goes from my speaker passenger side rear door is dead, would I be able to use this to test the wire to see if there's power?** A: You. Will need 12v tester **Q: Do i manually switch from "lo" to "hi"? pressing the green "sensitivity" button on mine does not switch to "hi".** A: Mine does not even turn on. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to use and I'm not dead! *by D***N on 22 January 2024* So, there I was, my old voltage tester probably living its best life under some floorboards somewhere after my last job, and me in dire need of a new one.

With a built in torch to assist in dark areas during power outages. The unit comes with clear instructions and the build quality is excellent. A great tool that could save you from a nasty shock. ### ⭐⭐⭐⭐ Same as a mains tester screw driver *by G***M on 17 January 2024* A little slow and difficult to activate but once set up identifies live wires BUT only if you touch them. Seems to do little more than a mains tester screw driver with a beep and red flashing light. The LED spot light is useful.
