With regards to the steps in using a Zircon stud finder, you can watch a demonstration here:

Why Is Stud Finder Calibration Important?

Calibration means allowing the Zircon stud finder to identify the hollow behind the wall, so that it will alert you if an unusual thickness is detected.

At first, it will use a weak electrical field until you slide it, and it runs into something denser. Simply put the unit on the wall before pressing the "on" button.

For example, you calibrated it on a dense part of the wall. It may falsely alert you that the hollow is the stud. However, the stud finder will most likely recalibrate.

It's hard to scan tiled walls using StudScan or DeepScan mode. It may not detect the stud properly due to the tiles' thickness. However, you can use a MultiScanner to identify the screws and nails beneath the tiles.

It May Not Detect Everything

If the studs or wires are two inches behind the walls, then the stud finder may not detect them. It's a common problem when the wall is too thick. That's why you should not assume that there are no wires behind the wall.

Always refer to your house's blueprint to identify where the wires are located. Otherwise, you may need to ask the house contractor to find such wires.

Can You Find a Stud Without Zircon?

You can actually find studs without a tool. However, it may take you longer than using a stud finder. A finished wall may be difficult, especially if there's no visible wood framing.

See below for the steps to find a stud manually:

  1. Check where the light switches or power outlets are mounted. There's most probably a stud behind them.
  2. Tap the wall and listen to it. A hollow sound is louder, while studs are quieter.
  3. Mark the spots where you suspect the studs are. You can use a temporary marker.
  4. Using a magnet, find the screws and nails behind the wall. However, the effectiveness of a magnet will depend on its strength.
  5. Try drilling a hole in your markings to find out if there are studs.

How Many Studs Are Behind the Wall?

The number of studs differs per home. It can be due to house structure or measurement of the area. However, there's a way to estimate how many studs are hiding behind a wall. See the steps below:

  1. Measure the wall length in feet, then convert it into inches.
  2. Divide the measurement by the stud spaces, which are usually 16 inches.
  3. Round off the result to eliminate the decimals.
  4. Plus one to the rounded off value.
  5. The last amount should be the estimated count of studs.

Now, let's put it into an example.

  • Let's say the length of the wall is 32.5 feet. When we convert it into inches, we'll have 438 inches.
  • Next is to divide 438 inches by 16 inches, which will give us the amount of 27.375.
  • If we round off 27.375, we'll have 27. Then we can add one to it, and the result is 28.
  • Therefore, a wall with a length of 32.5 feet has approximately 28 studs.

Keep in mind that the final value may vary depending on the construction of walls.
