How accurate is the center detection and live wire warning?
Advanced models (e.g., SF2 Pro & SF4) feature ±5 mm center accuracy with a clear center-mark arrow and percentage indicator (0–100%). Live AC wire detection triggers both visual flashing and loud beeping alerts when within 10–50 mm of energized cables (90–1000 V).

Can it be used on different wall types and uneven surfaces?
Yes. All models auto-calibrate on drywall, plaster, lath, and tiled walls. The upgraded sensor and “Deep + Metal Scan” modes ensure reliable performance even on textured or slightly uneven surfaces.
