Discover the Power of Laser Levels

By Ava Brown, May 4, 2017

Imagine this situation: You are standing up on a chair with a nail and a hammer in one hand and a level in the other, trying to hang your wedding picture. But the problem is, you are physically incapable of holding the level in place while you hammer in the nails. If only you had an extra arm to do this… If only the level could somehow miraculously hold itself against the wall…

Guess what? Your wish has come true! But not the one where you are a three-armed mutant.

A laser level is a tool invented to specifically tackle this kind of problem that not only you, but many engineers and construction workers face. This piece of equipment projects a perfectly straight laser beam across a surface while being mounted on a tripod or even on the wall, leaving your hands completely free. With the help of a level laser, DIY projects like laying kitchen tiles, hanging a mirror or installing a cabinet are much more simplified.

But besides helping homeowners to do some small improvements around the house, laser levels are most important in construction and civil engineering, cabinetry, and road work. Grading, surveying and landscaping companies also greatly depend on a level laser to finish their tasks flawlessly. Actually, any activity that needs precise and straight measurements over a large distance can benefit from a level laser. All laser levels have two basic components – the laser and a leveling base that can be put on the floor, attached to the wall or on a tripod. However, different types of laser levels work differently.

A point generator is the simplest and least expensive type of laser level. It includes a bubble inside a vial that the user needs to line either by a knob or by repositioning it. In other words, it’s a spirit level that shoots a laser point. This type of level is best suited for home projects that don’t require 100% accuracy. The dot laser is more versatile than the simple point generator because it projects a dot that can be level, square or plumb. It comes in a wide range of models for indoor and outdoor use.

Line lasers use a point-to-point laser technology to shoot multiple horizontal and vertical lines over a distance of 19.8 – 30 meters. They have multiple LED diodes with many models, including a pulsing light technology for better visibility.

The most advanced type of laser levels is the rotary level. It creates a 360 degree line by projecting a rotating dot. It has a detector to help you read the laser lines over long distances. The rotary laser level is the most precise and expensive level mostly used in industrial environments, laying foundations and pipes or grading roads. They come with self-leveling and manual options and can also be remotely controlled. Some models used in grading work are so large that they need to be mounted on a tractor or platform.
