- Does this wall scanner come with the battery included in the box?
- No, the package does not include the required 9V battery. You will need to purchase a standard 9V battery separately to power the device. The scanner itself features automatic shut-off to help save your battery's life.
- Do I need to manually calibrate this stud finder before using it?
- No manual calibration is needed because the tool calibrates itself automatically. Just select your desired scanning mode and place the device flat against the wall. The digital LCD screen and audio signals will guide you from there.
