3/4-Inch Depth Wood and Metal Detection

The ST102 stud finder locates wood and metal studs up to 20 mm deep behind walls, floors and ceilings. It works on surfaces such as lath, wallpaper, wood flooring, acoustic ceiling and painted walls. The tool suits homeowners, DIY enthusiasts and professionals who need to anchor heavy items securely.

Calibration and Detection Limits

Press the button to start a 1–2 second calibration beep; a steady green power light confirms readiness. Hold the button while sliding the scanner to find stud edges. The detector cannot sense objects deeper than the stated 3/4-inch range and may give false readings if metal jewellery is worn during calibration.

Battery and Handling Check

A 9 V 6F22 battery is included and powers the unit. Remove any rings before calibrating to prevent metal interference. The compact 5.78 x 2.44 x 1.26 inch body fits in a drawer or toolbox for storage between jobs.

Questions about this item

Which depth setting should I choose for a standard 3/4 inch drywall?

The ST102 detects wood or metal studs up to 20 mm (3/4 inch) deep in drywall, plaster, lath, wallpaper, wood flooring and acoustic ceiling. No selectable depth settings are required; the single sensor range covers that thickness.

What does the 20 mm detection depth mean when I slide the unit across a finished wall?

It means the sensor can sense the edges of studs, joists or pipes buried up to 20 mm behind the surface. As you approach a target the LED direction arrows light and the beep rate increases, letting you mark both edges before drilling.

What interface does the ST102 use and what does it limit in practice?

The tool is a standalone handheld scanner powered by the included 9 V 6F22 battery. It has no data port or wireless link, so all readings are shown only on its built-in LEDs and audible alarm.
