The Bullseye Auto-Leveling Laser and Stud Sensor from Black and Decker is certainly not the only one of its kind on the market. However, for the sake of simplicity, we are just going to talk about this particular product.

The days of having to put the manual leveling tool on top of your picture frame as you hang for dear life on the ladder are finally gone. You simply attach the tool to the wall and it will automatically project a laser light to guide you as you place picture frames, shelves and other decorative items on the wall. The Bullseye Auto Leveling Laser also finds wood, metal studs and live A/C wires as you scroll it across the wall — this comes in handy when you want to hang those heavy art pieces on the wall.

There are many versions of these: some calculate distances (laser tape measure); others give you both a horizontal and vertical level; while others even help you space out your picture frames to the millimeter.
