It is very easy to use and the non-contact feature gives me peace of mind when working around outlets. The sensitivity is great and it feels like a very safe, accurate tool to have around the house. Highly recommend! Review: Exactly what you are looking for - Saved my butt, and it works really well. Why it saved my butt? I changed two smoke/CO detectors without this and it went well. Decided for the following six I planned on changing that I should get this device. Sure enough, halfway through while using it one of the black cords was live even though the light next to it turned off when I flipped the breaker. Went back and flipped a few more and the reading was at zero. Game changer! Additionally, it’s easy to use, has a useful light, and can clip on your belt loop. ## Features - 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 and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected - NON-CONTACT: With NCV inductive probe for AC voltage; Just place the 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 Test. Handy circuit tester for electricians, homeowners - DUAL RANGE: Detects standard and low 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, and the percentage value can display the voltage signal intensity more intuitively - SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines - COMPACT DESIGN: Bright LED flashlight for work in dim ares; Low-Power-Indicator when battery voltage is below 2.5V; Automatic Power Off after 5 minutes without operation or signal detection; Pocket-sized, 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 ### ⭐⭐⭐⭐⭐ Highly recommend *by C***N on August 5, 2026* This voltage tester works exactly as expected.
