Summary
4.0 stars, 14,200 reviews. The most-sold stud finder in the US. Works well on single-layer drywall. The SpotLite pointer shines a spot on the wall where the stud edge is. False-positive complaints are common, especially on textured walls. Edge detection requires marking two edges and calculating center.
