Whether you’re building a shelf or sanding something down, creating leveled surfaces is of the utmost importance. After all, if your shelf is unbalanced, everything you put on it will roll off the side. Normally, this is accomplished through a level tool, which is just a few air bubbles suspended in liquid on a big ruler thing. It’s a bit low-tech and may not always be accurate. If you want a true level, you need laser precision, literally.
Ryobi’s Compact Laser Level does have a pair of the usual bubbles, but that’s not the crux of the device. The real show is the 20-foot red laser line, projecting perfectly straight outward to clearly indicate a level surface. Whether you’re building the shelf or putting it up, the Laser Level will show you where the true level lies. Using Ryobi’s proprietary Air Grip tech, you can also attach the laser level to any flat, smooth surface, whether it’s a wall or a ceiling. The Compact Laser Level is available at Home Depot for $36.97.
