Back when the first stud finders came out, we thought they were the greatest thing since sliced bread. But technology's brought those old stud finders into the 21st century, and here we have Strait-Line's Wall Scanner 150, aptly named because it does so much more than find studs-—it could save your life. Accuscan technology locates not just wood and metal studs, but live A/C wires and pipes behind three surfaces: drywall, paneling and tile. And funny how when your old stud finder lit up, you never had that pencil in hand to mark the stud's edge. You won't need one anymore, thanks to the clever built-in marking element on the Wall Scanner. Just press the button when the liquid crystal display indicates a stud and the unit beeps, and you'll get a clear mark. Since it runs on batteries, we think it was great of Strait-Line to give it automatic power on contact, and an integrated belt clip keeps the tool handy. Strait-Line left no room for improvement on this one.--Kris Jensen-Van Heste
