Center Finders vs. Edge Finders

The original Zircon® StudSensor™ tools, and all other stud finders from every other brand, use Zircon's edge-finding technology. You can read up on How Stud Finders Work, but basically the device scans the wall, and when it detects a change in wall density it knows it found a stud edge. Once you find both the stud edges you can work out where the center of the stud is. (This page explains how to use an Edge-Finding StudSensor product.)

Zircon's Center Finders, the only stud center-finding devices on the market, use our new patented technology to find the center of a stud, so you know where to nail, drill, or hammer after one pass across the wall. (This page explains how to use an Center-Finding StudSensor™ product.)
