Review on 🔍 Stud Finder Wall Scanner: Upgraded Smart 5-in-1 Multi-function Sensor for Metal, Studs, AC Wire, and Pipe Locator in Walls by Gene Evans

The product itself works well or probably better than most similar products, but I really hate the user manual. The English language is a bit strange, but not that bad, so it's ok (I'm used to it). The manual is divided into six main sections, namely: 0. Multifunction wall scanner (features or product specifications)1. Inserting the battery (Once I inserted the included battery, the device showed a low battery warning, so I used mine instead)2. Operating Tips3. Look for a hairpin4. AC cable warning5. Warning. Oddly enough, the User Tips section is the longest section of the guide and first covers calibrating the device without going into too much detail. But this section is the longest. one has to wonder how to calibrate the device while reading. This greatly upsets the reader. Then, when you get to the Finding Studs section, you can "sort of" get an idea of how to calibrate the device. You can start scanning the wall after the indicator bars on the display disappear (calibration complete) as the manual says, but the manual forgot to mention pressing the scan button to make the decreasing bar appear and the Calibration starts. So the correct calibration procedure is: 1. Press the mode switch and select the desired mode2. Place the device on the wall3. Press the scan button (but don't move and try to scan at this point) and wait for the zoom bar to disappear from the screen4. Start scanning. I think the management also forgot to mention two other things. First, scanning the wall requires the user to constantly press the scan button, as other scanners (perhaps older?) require. With this device, once the calibration is complete, you do NOT need to hold down the scan button while scanning. Another thing the manual forgot to mention is the scanning direction. It doesn't matter if you move the block to the right or left. Sometimes you will see a left or right arrow on the screen. These arrows mean that you must move the device in the direction of the arrow because you have passed an edge of the ledge (the direction the ledge is actually located). Thus, the device attempts to accurately determine the center of the tip. Since this device shows you the "center of the stud", the arrows do not mean that you have to move the device to find the other side of the edge in order to see the center of the stud as the center of your freehand markings. . When the arrow appears, simply move the device in the direction indicated by the arrow (this may happen left or right a few times or more in a row) and let the device find the center. Another thing to mention in the guide. is that, as indicated in the Operating Tips section, in AC (AC) scan mode you must put the instrument in the air to calibrate it. Please do not calibrate the instrument on the wall, otherwise it may not recognize the wire. The language is a bit strange, but understandable, so everything is fine here. The problem is in the warnings section of the manual (although most of the information is not descending). There it says to press the tool against the wall and then press the scan button. Wait for a beep to confirm calibration is complete before moving the instrument. Since I don't use AC mode I don't care, but how should I calibrate in AC mode, in air or against a wall? I like the product itself. Since many things exist behind the wall, there is no such thing as a perfect spike finder that can be trusted 100%, but this product is pretty accurate. But as I mentioned above, this very disorganized user manual leaves you frustrated when you're wasting your time with these kinds of supposedly simple tools.
