Detection Depth and Surfaces

Precision 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 Precision 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.

Yes, our Precision Sensors stud finders have been tested on both light and very heavy textures and have consistently and successfully found studs through texturing.

See “How deeply do Precision Sensors stud finders read?” above.

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.

It depends. The determining factor is the density of the surface you are reading through. Precision 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.

It is not recommended. Concrete is too dense and thick. Stud finders are designed to detect through walls and ceilings.

Trouble Shooting

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.

Make sure you press and continually hold the button down until you have completed your scan.

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.

Helpful Tips:

  • 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.

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.

Wait until the wallpaper is dry. Wallpaper may take up to 2 weeks to dry sufficiently.

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.
