Tavool Stud Finder - 4 in 1 Electronic Wall Scanner Detector Wooden Metal Stud Sensor Locator Beam Finders Edge Center Finding with LCD Display for Wood AC Wire Metal Studs Detection

I read and listened to a lot of reviews while choosing stud finder. That's how I chose this one. It works great, is lightweight, and easy to use.

Used it and not working. Ended up damaging the electrical wire I side the wall.

Handy to have

Arrived quickly. Seems like a solid unit. Supply your own 9V battery. Works as a basic studfinder for drywall just fine. Gives you a nice 5 second countdown for the calibration time. Gives you the right or left edge, and the center of the stud nicely. The electrical wire presence seems to work pretty accurately, but I would be careful with trusting any tool for that. It detects changes in density so pipe location might work sometimes, again I'd be careful trusting any tool for that vs an actual visual look. As a locator in tile for stud or wire or pipe, not the right tool. Overall, a nice spare studfinder to have for me.

I'm very happy with this tool so far. It has a good heft, bright back-light display and gives accurate results.Note that the AC-wire detect mode has a range of 2" this means that a wire at the back of a standard stud cavity of 3.5" would likely not be detected. Similarly the metal detect mode is advertised at 2.36", so again a pipe at the back of a wall cavity might not be detected.

Instructions are fairly clear, although I have to point out that they read as if they were written in another language and translated to English. Not a huge deal, but some words/phrases are not used correctly or don't 'read' the way they should. No points docked for this, it's a stud finder. They've been made the same for decades and they operate the same.So far, this studfinder is doing well for me for some around-the-house projects. I really like how the display alerts me to the left, right, and center points of a stud. I also like how there's different "modes" such as "deep" (for thick drywall), metal (for studs), and AC (can detect if there's wiring behind the drywall). So far I have no complaints.I will say the "calibration" part is a con. It's not that it takes that long or is overly difficult, but before using EVERY TIME, you have to "calibrate" by putting the studfinder on a part of the wall where there are no studs, hold a button for 5 second and wait for a beep. This is to let you know it's done and it's ready to search for studs.It's a 'con' because I can imagine a lot of people don't know how to locate studs WITHOUT a studfinder, and they're probably going to think it's broken/not working if they just use it straight out the box without calibrating first.

overall it worked good, just a few times after calibrating it was giving false readings for studs that was not there.
