In Eugene, Oregon, a DIY homeowner almost drilled into a wall to mount shelving. Before starting, they ran a stud finder across the area and immediately hit a warning for live wiring.
The project stopped right there. What could have turned into damaged wiring or a safety issue was avoided in seconds. Other users commented that they learned the hard way by skipping this step.
Moments like this are why simple tools matter. They are not about speed or convenience. They are about avoiding problems you cannot see.
