Line Lasers: 5 Fast Facts

Fact #1. Line lasers convert the energy from a battery into concentrated, optically amplified light using a laser diode. The powerful beam this diode creates is passed through a cylindrical lens. This focuses the laser into a long, straight line. That might seem complex and cause one to assume these are expensive devices. Indeed, you can spend nearly four hundred dollars on a quality model. However, you can also find decent versions for less than fifty dollars.
Fact #2. Any unit worth consideration projects both horizontal and vertical lines. These two axis options can be used independently. This helps you keep rows of flooring straight or frames level in the horizontal application. It can also help you align beams or sheets of drywall vertically.
Fact #3. Make sure the option you consider has a self-leveling capability. After all, if it isn't leveled, there's no way the work you do will be level either. This self-leveling mechanism is usually controlled by an internal pendulum and a series of magnets. It precludes the need for a person to trust their own eyes and hands using a bubble level.
Fact #4. Many of these items come with adapters. This allows them to be attached to pipes, beams, or other surfaces. Others are designed to be placed on tripods. The type of work for which you will use the device will help to dictate which type of attachment method will work best for you. Plumbing, framing, or tile installation may require different approaches, for example.
Fact #5. Calculate your tolerance for slight inaccuracies and weigh that against the cost of a line laser. A less expensive option might be accurate to a certain distance at forty feet. A pricier and more refined model will boast a closer accuracy at that same distance.
