## Before you buy

- The listing states that calibration is needed before each measurement and again if the scanner is shaken or lifted. It says to switch to AC mode if a wire icon appears in any mode, and to turn the scanner off when drilling.
- Listing details are inconsistent about battery specification: one field says a 9V battery is included, while another identifies the cell type as Lithium Ion. The package-size field also gives 240 Grams while a separate item-weight field says 240 g, and another description gives different package dimensions. Confirm the selected listing's battery and package details before purchase. Detection descriptions and stated depths are manufacturer claims, not independently verified performance.

## In the box

- KUUAUX Stud Finder \(1\) (Included)
- 9V battery \(1\) (Included): The listed battery type conflicts with another battery detail. Check the selected listing.
- User manual ×1 (Included)

## A good fit for

- DIY users locating wood studs before mounting shelves, frames or cabinets.
- Homeowners who want metal and live-wire scanning alongside wood-stud modes.
- Users who value both an LCD indicator and an audio alert while scanning.

## Less suited to

- Buyers who need a tool that requires no per-measurement calibration.
- Anyone seeking a substitute for appropriate electrical safety checks. The listing's wire detection claims do not establish that an area is safe to drill.

## Customer feedback

Customer feedback describes the scanner as accurate, easy to use and precise, including a report of quickly locating studs behind drywall. The LCD is also described as clear and helpful, though one customer found it hard to read. Views on functionality and value are mixed, with reports that it can work well alongside hit-and-miss experiences. That variability matters for a tool whose listed use depends on calibration and careful movement. Aggregate ratings are also mixed, so the feedback does not establish consistent performance for every wall or job.

- Positive themes: The display is described as clear and helpful by some customers.

The listing describes wood-stud scanning at three depths, plus metal and AC-wire scan modes. It also names pipes among detectable objects.
### Does the SH402 need calibration?
Yes. The listing says to calibrate against the wall before each measurement and to recalibrate if the scanner is shaken or lifted.
