VENLAB Voltage Tester, Non Contact Voltage Detector, Dual Range Voltage Sniffer, Tick Tracer 12V-1000V, Voltage Sniffer with Alarm and Flashlight, Live Wire Tester, Circuit Tester

What a lifesaver! I'd been searching for a 120V line voltage detector for ages, but they were all over $50, and some as much as $160. Then I saw this beauty! Inexpensive! Easy to use! Compact! And again, a lifesaver! I had a large bundle of 120V Romex in the attic space. Unfortunately, determining which one to use was the issue, and there was no way I was going to spend hours and hours cutting little notches in them and test with my multimeter. So the bundle stayed left alone for quite some time. That was until I purchased this gem. I was able to determine the correct line in under 20 minutes! Now theres a 2-gang outlet which now runs the attic fan and LED light! Next was tracing wires in the garage walls. The previous owner had a small shop and added an additional fuse to the panel. He also added an additional run of outlets, but they were at different heights. As a few were up high, I couldn't tell if the wiring ran along the upper area of the wall or back down? I'm glad I had this tester! He did run a few outlet wires along the upper interior wall! If I hadn't checked, I would most certainly have cut them! If you're in need of a user-friendly line voltage tester, this is the one to get! I LOVE this tool!

Excellent quality and good proce

Works great. I was able to detect a stray live wire causing problems in a matter of seconds. Definitely a must-have tool for any serious electrical work and diagnostic tests. Good value for money.

J’ai acheté ce produit parce que je fais des rénovations. Je change les vieilles prises de courant et interrupteurs ainsi que les luminaires qui datent de la construction de la maison. Ce testeur de tension m’aide dans cette tâche. Il est facile d’utilisation et fiable. Les batteries sont incluses. Un bip indique que l’appareil est fonctionnel lorsqu’on appuie sur le bouton power. L’appareil est muni d’un pointeur laser et d’une lampe torche pour les endroits peu éclairés. Un signal sonore et un voyant lumineux rouge indiquent la présence de courant. De plus, la forme de l’embout permet de le rentrer directement dans la prise avant de couper l’électricité et juste après. On n’est jamais trop prudent. Je le recommande.

This thing is so useful and you can change the sensitivity which is great. It's so strong it can read power coming from a wire or outlet a few inches away!
