It works !
Well it worked great I had a feeling a gas pipe in the wall exactly where i thought it said yep. So in one use it paid for itself I’d say. Played with it all over the walls found old pictures pin nails and stuff. Very sensitive. It picks up metal / wood at about 100mm away then using the three lights you then can narrow it to a pin point ? It’s good worth the purchase. Worthwhile purchase

Working better than expected whilst testing it out
Used to test it works and at initial testing it did. I put it against my internal stud wall and it was able to pick that up. Also tested it near some socket cabling I knew was located in that area from installation and it picked this up. Cannot complain thus far but have not had to use it for a project yet.

Don't bother, the video doesn't the reality if using this
Not particularly good and poor at finding studs. Buy a proper tool Ryobi or another premium product

Excellent 👌👍!
Very handy tool! The stud finder is accurate for detecting wood, metal, and live wires. The depth tracker works well and the display is clear. Compact and easy to use, perfect for DIY jobs around the house. Helps avoid drilling into cables or pipes. Great value for the price!

Dangerous and unless. Safer in landfill than your home.
Aparently a piece of 2x4 has power running through it and so does my door..... Most useless piece of kit i have ever bought. Beeps at its own shadow. Detects electric where there is none and doesn't detect where there is cables. Bought to replace an aging detector which was on its last legs and its actually scary how bad it is. Ended up in the bin before it caused an accident with its false readings. Avoid unless you want to randomly drill holes in your wall chasing false readings or want to experience the thrill of screwing through a power line with your drill. HANMATEK definitely a brand to add to the avoid at all costs list.

Reliable Stud Finder with Room for Improvement
The HANMATEK Stud Finder SF1 Wall Scanner is a 4-in-1 electronic stud sensor that promises accurate stud detection. While it performs adequately in most situations, I did encounter some issues when using it on the ceiling. The stud finder features multiple scanning modes, including stud detection, metal detection, AC wire detection, and deep scanning. In most cases, it accurately located studs within walls, making it a useful tool for various projects. However, when attempting to locate studs in the ceiling, I found that the accuracy was inconsistent. The stud finder missed a few studs, which led to frustration and additional time spent trying to find them manually. This limitation may be due to the angle of the scan or the density of materials in the ceiling. On the positive side, the stud finder is compact, lightweight, and easy to handle. The LCD screen provides clear and intuitive readouts, making it user-friendly. The built-in marking feature allows you to note the detected stud locations for convenience during the project. The battery life is decent, providing sufficient power for extended use. The device also includes a handy auto-shutoff feature to preserve battery when not in use, which is a nice touch. Overall, while the HANMATEK Stud Finder SF1 Wall Scanner performs well for most stud detection tasks, it falls short when it comes to accurately detecting studs in the ceiling. For wall applications, it is a reliable tool. However, if you primarily need to locate ceiling studs, you may want to consider alternative options or rely on manual methods for greater accuracy. Pros: Multiple scanning modes for versatility Compact, lightweight, and easy to handle Clear LCD screen for easy readouts Built-in marking feature for convenience Cons: Inconsistent accuracy in locating ceiling studs

Product is not same as per advertisement image or specifications shown on Amazon portal. The function is also not same. Your money and time both will be waste.

Este detector de pared es una herramienta muy práctica para hacer arreglos en casa. Sirve para encontrar cables, metales y vigas de madera escondidas dentro de paredes, techos o suelos, y es bastante fácil de usar. Tiene una pantalla donde ves todo (posición, profundidad, batería, etc.), se calibra con solo pulsar un botón y te avisa con sonido y luz cuando detecta algo. En cuanto a lo importante: detecta bien metales y madera, pero los cables eléctricos solo los encuentra si tienen corriente. También puede fallar un poco si la pared tiene humedad, así que conviene comprobar bien antes de taladrar. Como extra, también detecta tuberías, lo cual viene genial para no liarla al hacer agujeros. Trae una funda protectora para protegerlo al ser almacenado. En resumen, es una herramienta muy útil y fiable para bricolaje en casa .
