This little device attaches to vertical and horizontal surfaces, adjusts via three screw-type feet, and then projects a beam to simplify the installation of items along the level line. Sure, there are zillion-dollar units designed for professional cabinet installers, but at just $30, this one looks like it’d be great for hanging pictures and such.
It comes with a small case and runs off two common AA batteries. It also ships with two wall attachments: a drywall type and a keyhole type. You can also mount it on a tripod or other stable surface for trickier installs. Two built-in level vials assist in alignment.
It’s not fancy, but hey — it’s not expensive, either.
