Stud Finder Wall Scanner
Whether you are hanging pictures, putting up a new set of shelves or getting ready to start an addition, knowing where the studs are in a wall can be extremely handy! And A good stud finder can be the difference between a successful DIY home project and disaster. That is why a stud finder is important.
JAXWQ stud finder uses UPGRADED SMART SENSORS which can sense the change in density in the space behind the wall and locates the stud center with GREAT ACCURACY. You will not worry to drill many error holes on the wall while putting up a TV bracket, shelf unit, or even just a set of coat hooks on drywall.
How to use AC mode
Note: If in AC scan mode/Metal scan mode, you need to put the tool in the air to calibrate it.
Step 1: Put the tool in the air and press the ON/OFF button to turn on, then choose AC mode or Metal mode.
Step 2: Press Calibrate Button to start calibration, the decreasing bars will disappear the buzzer will beep one time and the calibration is completed. Then releases the scan button.
Step 3: Place the whole device against the wall, slowly slide the tool across the surface. Mark the location where you get the highest AC indication (the most Middle bars on the screen). (Figure A): If it is a strong target, the top indicated arrow will show, and a steady beep will sound. Continue in the same direction until display bars reduce. Reverse direction and mark the spot where the display bars peak from the reversed direction. The midpoint of the two marks is the location of the center of the live AC wiring. If the unit indicates live electricity over a large area, you can reduce the sensitivity of the tool to refine the scanning area and more accurately locate the live AC wiring by following steps 4 and 5 below.
Step 4: (Figure B) To further pinpoint the location of the live AC wiring, scan the area again. Release the Scan button and then turn the unit back on, this time starting on the wall over one of the previous marks. This will reset the tool to lower sensitivity and narrow the scan area.
Step 5: (Figure C) Scan in both directions as in Step 3. The area indicated should become smaller so you can more precisely identify the location of live AC wires.
For the Frames of Figure A B C, please kindly check the instruction in the package.
Stud Scan Detection
This stud locator has 3 stud scan modes. Deep Scan Mode scans through 2 layers of drywall up to 1.5 in. (38 mm) deep. DeepScan Mode is a higher sensitivity scanning mode that should be used when there are extra layers of wallboard or paneling. To minimize false positives and/or finding other objects further behind the wall that may not be a stud, always start your scan in the 0.5in. or 1 in. StudScan Mode first.
After you detect the center of an object, Please Use Metal Scan to determine if the reading in Stud scan mode was a wood stud, metal stud, or pipe.
Metal Scan Detection
JAXWQ wall detector can locate metal studs in StudScan mode, DeepScan mode, and Metal Scan Modes. Since JAXWQ stud finders are looking for a change in density behind drywall, not a particular material, in StudScan and DeepScan Modes the detector will react to metal studs the same as it would for wooden studs.
Wire Warning Detection
Wire Warning detection indicates the presence of live, unshielded electrical wiring up to 2 inches (51 mm) deep. For Safety, in all modes, this wall scanner always detects and indicates the Live AC Wire.
Note: WireWarning Detection works in both StudScan / DeepScan / MetalScan Modes. The WireWarning Detection Icon will flash when live, unshielded wires are detected.
Step 1: Calibrate the tool before every scan
Place the whole device against the wall, then press and hold the calibration button( on the side of the tool) to calibrate this tool. Wait for the reducing bars to disappear and beep to confirm calibration has been completed.
Note: In stud/deep mode, put it on the wall where you want to detect to calibrate it; In AC/Metal mode, put it in the air to calibrate it.
Step 2: Scan the wall
After finishing calibration, please release the calibration button. Then move the stud finder along the wall slowly, if you shake or lift the scanner accidentally, the device needs to be re-calibrated.
Step 3: Find the location of the stud
When the signal bar is full and the beep alarm is loudest, it means you have found the center of an object. Mark it with your pencil.
Then choose the Metal Scan mode to test whether it is a metal. After you confirm that it is not a metal, it means that you found the center of a stud. (More details refer to the above description of "Metal Scan Detection")Then you can drill it to hang the thing.

Very helpful. Just read the instructions so you understand what you are looking for.

I swear, I've had so many of these things throughout the years that don't work properly. So far every time this thing has told me that there was a stud behind it and I drilled in, it hit wood instead of empty space. Even my husband was acting very skeptical when I told him how well it worked. Lol

I bought to hang some picture and clocks on the wall. It did the job in finding the stud. Only reason for docking a star is that the center varies when finding the same stud. After going over the same stud the exact center location was close but never the same

I have been trying to make this product work for last few months. With a lot of effort with calibrating it at known stud positions etc… (which is ridiculous coz if I knew my stud positions why would I need it?) I was able to make it work a few times. Today, after calibrating it a few times at the studs where my tv is mounted, I went back and drilled where it told me to, and there was no stud there. Don’t buy. Go for a better product.

Purchased this for my husband as we've moved to a house that's over a hundred years old and has had lots of modifications over the years.He's found the instructions quite unclear (me too) . It works well, as in having the necessary beeps and graphs - but does require better, more informative instructions.We ended up putting it aside for now as we ran out of patience. But maybe it's just us?
