With a Zircon stud finder, when should you press the power button?

After the tool is flat against the wall.

  1. Before you lift it to the wall
  2. After sliding it once across the wall
  3. After placing it flat on the wall ✔

Why: Zircon says to always place the tool on the wall before pressing the power button. It calibrates the moment you press, so if you press in the air it calibrates to thin air, not your wall.

Huh, didn't know that: Zircon says a continuous blink and beep means a calibration error, so try again from a different starting spot.

The dad joke
That stud finder beeped near me. Guess I still got it.
