Our take on the Black+Decker BDL190S Line Laser With Stud Finder

The Black+Decker BDL190S is a two-in-one tool: a stud sensor that locates wood and metal studs and live AC wiring, plus an auto-leveling laser that projects a horizontal line. The laser levels itself without manual adjustment, so you can set a line for shelves, pictures or cabinets without a bubble vial. It runs on one AA battery and weighs about a pound. It suits homeowners doing occasional hanging and mounting work who want one handheld tool instead of a separate stud finder and line laser. Against dedicated stud finders it adds the laser line; against pro cross-line lasers it gives a single horizontal line and a simpler sensor, which is the trade-off reviewers note.
