How it Works/Functionality
- How do I turn on my Franklin Sensors stud finder?
Just press and hold the button and begin scanning.
You can press the button before or after you place it on a wall.
In contrast, other stud finders have a specific set of steps that must be followed precisely for them to operate correctly.
- How do I calibrate my Franklin Sensors stud finder?
You don’t need to. Just press and hold the button and begin scanning to instantly detect studs.
- Why don’t I need to calibrate my Franklin Sensors stud finder?
Conventional stud finders can only see the wall in one location at a time – as a result the user must slide the finder back and forth across the wall to “learn” the wall. However, Franklin Sensors stud finders have multiple sensors that allow them to see the wall in several locations at once and learns the wall instantly for a more accurate reading.
- How do Franklin Sensors stud finders see into the walls?
Franklin Sensors stud finders charge and discharge its sensor pads thousands of times per second and senses how difficult it is to charge and discharge the sensor pads. Regions that are near a stud are harder to charge and discharge. Franklin Sensors stud finders have high precision circuitry that uses these readings to identify the precise location of studs.
- How do the electronics in the Franklin Sensors stud finders compare to the electronics in other stud finders?
Most electronic stud finders were designed several years ago using older electronics and/or older technology. The first Franklin Sensors stud finder was introduced into mass production in 2011 and uses the newest electronics. Additionally we are continually testing and researching new technologies to provide the cleanest most accurate readings.
Our patented Multi-Sense Technology has more sensors than conventional stud finders, resulting in a larger sensing area and deeper, more accurate stud detection.
- What makes Franklin Sensors stud finders accurate when conventional stud finders are not?
Conventional electronic stud finders rely on a reading from a single point on the wall to determine whether or not a stud is present. If there is an inconsistency in the wall at the point of the reading, the readings may be incorrect.
The Franklin Sensors Multi-Sense Technology reads multiple points on the wall resulting in a larger sensing area and deeper, more accurate stud detection. The wide horizontal LED display shows the stud edge and center simultaneously.

Detection Depth and Surfaces
- How deeply do Franklin Sensors stud finders read?
Franklin Sensors stud finders sense more deeply than conventional stud finders in both ideal and real-world conditions.
Walls are full of inconsistencies. They aren’t perfectly straight, sheetrock sometimes contains bubbles, paint is applied in different thicknesses and in many regions of the world, some form of texture is applied to the wall. Conventional stud finders can only be tuned to one type of condition and therefore are inconsistent in varying conditions. The Franklin Sensors Multi-Sense Technology allows our stud finders to read more deeply, not only in ideal conditions, but also in real-world conditions with inconsistencies and differing surface types and thicknesses.

- Do Franklin Sensors stud finders work through textures on walls and ceilings?
Yes, our Franklin Sensors stud finders have been tested on both light and very heavy textures and have consistently and successfully found studs through texturing.

- Do Franklin Sensors stud finders work through lath and plaster walls?
We have tested our sensors on several lath and plaster walls and it worked successfully on all of them. However, electronic stud finders only work if the wall surface is reasonably uniform. If a lath and plaster wall has a high degree of inconsistency our stud finders may not work well, or not at all. We cannot guarantee its performance on all lath and plaster walls.
- Do Franklin Sensors stud finders work through exterior walls, floors roofs and tile?
It depends. The determining factor is the density of the surface you are reading through. Franklin Sensors stud finders read more deeply than conventional stud finders.
Helpful Tip: If your surface is too thick try checking for studs through the opposite side of the wall. If a surface is covered in tile, check to see if a high area on the wall does not have tile. Try taking your reading from an area without tile, either higher or lower.

- Do Franklin Sensors stud finders work through concrete?
It is not recommended. Concrete is too dense and thick. Stud finders are designed to detect through walls and ceilings.
- No LED lights are illuminating.
It could be a weak battery. Remove both batteries and replace with two fresh batteries. Replace both batteries at the same time.
If you have one of our smaller units, do not wear gloves when operating.
- The stud finder only works momentarily.
Make sure you press and continually hold the button down until you have completed your scan.
- The LED lights are indicating the location of pipes and wires, not just studs.
Our stud finders indicate change in density. The LED lights may indicate the location of a pipe, electrical wiring or other objects near the surface being scanned.
- Look for evenly placed studs on either side (16”, 24” on center, etc.)
- Scan above and below the location to confirm the results.
- Scan the sensor up and down the wall. Pipes and wires typically bend – thus the lights will turn off when you move away from them. A stud continues from floor to ceiling so the lights will remain illuminated.
- Use caution before penetrating the wall.
- I’m having difficulty starting a scan near doors and windows.
Solid headers and triple studs are often present around doors and windows. Our stud finders indicate a change in density. If all the sensors sense the same density, the LEDs will not illuminate.
Begin the scan away from the window or door. Then, move the stud finder to the area around the window or door.
- The stud finder doesn’t work through new wallpaper.
Wait until the wallpaper is dry. Wallpaper may take up to 2 weeks to dry sufficiently.
- I’m getting inconsistent readings.
There are a few things that might be happening so please try the following:
- You may be holding the unit near the base rather than by the handle. Only hold the unit by the handle with a finger continually pressing down the button.
- Sometimes after continuously scanning the wall for a period of time, the readings seem to be less consistent. Release the button and then press and hold the button down again.
- There may be anomalies in the surface material. Test at a higher or lower location on the wall.
- Are Franklin Sensors stud finders sold outside the United States?
Yes! Click on this link and we’ll show you where. Where to Buy
- Do Franklin Sensors stud finders have patents?
Yes. Both in the US and internationally.
- Are Franklin Sensors stud finders FCC compliant?
