HANMATEK Stud Finder SF1 Wall Scanner 4 in 1 Electronic Stud Sensor with Depth Tracker, Unit Change, for Wood, Metal, Cables, Circuits Detect in Walls

Great little unit, finds studs and metal with clear beep and lights. Good price, easy to use.

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 versatilityCompact, lightweight, and easy to handleClear LCD screen for easy readoutsBuilt-in marking feature for convenienceCons:Inconsistent accuracy in locating ceiling studs

Very easy to use and very accurate!A must-have tool for all DIYer!

Well constructed but a bit iffy on detection sometimes.

Cheep and easy to use. Works well at finding the studs in the wall. I have not had any issues with it

Most DIY forums say that there's nothing to detect studs reliably, so I wasn't expecting much from this. However, I took a punt and bought this to fit a ceiling clothes rack. It found 3 studs in my ceiling relatively accurately after a few passes of the device over the ceiling. Sometimes it didn't pick anything up but I kind of took an approximation of where the studs were from several attempts and then drilled tiny pilot holes to verify. It's best if you calibrate it first on a area where you know there's no studs (e.g. by tapping). It's quite expensive but it saved me a lot of worry and hopefully I can use it for other jobs.

This item was able to find the wooden stud that I needed to screw a hand rail to. Not perfect but found enough wood for me to use. Not used other capabilities of the item

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.
