3. Interpreting the Display
The LCD screen will show visual indicators and emit audio alerts as it approaches and locates objects:
- Signal Strength Bars: Increase as the device gets closer to an object.
- Arrow Indicators: Guide you towards the center of the detected object.
- 'CENTER' Indicator: Appears when the device is directly over the center of a stud or metal object.
- AC Warning Icon: Flashes with an audible alert when live AC wires are detected.
4. Specific Mode Usage
Stud Mode (3/4" and 1-1/2")
Use this mode to locate wooden or metal studs behind drywall. Start with the 3/4" mode. If no stud is found, switch to the 1-1/2" (Deep) mode for deeper scanning.

Metal Mode (2-3/8")
This mode detects various forms of metal, such as metal pipes, steel bars, or rebar, up to 2-3/8 inches (60mm) deep. It is useful for avoiding metal obstructions when drilling.

5. Optimal Performance on Wall Types
The Mecurate Stud Finder performs best on single-layer drywall. Performance may vary on other wall types such as stucco, tile, flooring, carpet, or roofing due to material differences. Avoid scanning in humid environments as this can affect detection accuracy.
