Zircon is the original electronic stud finder brand and still the most widely sold. Their StudSensor e4 is the budget entry point at $20, and the MultiScanner models add metal and AC wire detection. Zircon uses a single-sensor edge-detection approach, which requires two passes to find both edges of a stud.

Standalone electronic tool. Zircon invented the consumer electronic stud finder in 1980.

Frequently Asked Questions
Zircon vs Franklin Sensors: which stud finder?
Franklin shows the full stud width in one pass. Zircon detects stud edges, requiring two passes to find the center. Franklin is faster and more intuitive. Zircon is cheaper ($20 vs $50) and the MultiScanner adds wire/metal detection that Franklin doesn't offer. For hanging pictures, Zircon is enough. For renovation work, Franklin saves time.
Why does my Zircon give false beeps?
Common causes: plumbing pipes, HVAC ducts, electrical boxes, or drywall screws between studs. The AC mode on MultiScanner models identifies live wires. For pipes and ducts, try moving up or down 12 inches. Studs run floor-to-ceiling; pipes don't.
