Reviews Of The 5 Best Rotary Laser Levels

Why should someone consider chucking their tried and true water bubble leveling tool in favor of a rotary laser level? It’s a good question. If the answer is simply that the laser level is new, well, that’s not good enough. It has to have some real, quantifiable advantages before getting rid of something that’s worked for centuries makes any sense. Fortunately for proponents of the best laser levels there are a number of solid reasons to make them part of your toolkit including:

  • Simplicity and significant time savings.
  • Eliminating the need for marking guidelines everywhere.
  • Easily adaptable to indoor or outdoor applications, large and small.
  • Eliminating the need to reset should something or someone knock the level out of whack.

As with everything else though there are so-so laser levels, good laser levels and great laser levels. Below we’re going delve into what a rotary laser level is, review what we consider to be the 5 best laser levels available on the market today and then go into some of the things you’ll want to consider before buying one of these technical marvels.

Just what is a Rotary Laser Level?

The Best Rotary Laser Level uses a beam of light to create the equivalent of a chalk line that can be referenced to ensure things are properly oriented. The width of the beam is dependent on the size of the diode emitting it with narrower being better because it allows for greater precision. Early laser levels were limited in their power and so were limited in their usefulness; typically confined to indoor projects where the light they produced was easier to see. Today’s more powerful lasers mean that newer laser levels are equally effective both indoors and outdoors, where they are used on most of the world’s large scale construction projects including dams, skyscrapers and superhighways.

The rotary laser level rotates 360 degrees up to 1000 times per minute with some being effective out to 2000+ feet. In essence, they create a plane of light that is extremely accurate and negates the need for multiple readings and elaborately drawn reference lines.

Rotating Laser Level Applications

Regardless of how experienced and clear-eyed a contractor is there is virtually no way to avoid tiny discrepancies in leveling. Over 50 or more floors this discrepancy could add up to a building actually being several inches off kilter. This is one reason almost all large scale construction sites in the world today use precision rotating laser levels and why so many of today’s skyscrapers are confidently pushing beyond what was previously considered a safe height. But the usefulness of the laser level does not stop there. Other common uses of the rotary laser level include:

Choosing the Best Rotary Laser Level

There is a lot of equipment out there that looks great, but looks can be deceiving and professional salespeople can be very persuasive. In order to avoid being sold something you don’t need or can’t use there are several things you’ll want to keep in mind about the particulars of your work and/or the specific job you’re purchasing the rotary laser level to help you with. These include:

  • Range: If you primarily build private homes, home additions, decks and the like you’ll have no need for a rotating laser level with a 2,000+ foot range. If on the other hand you specialize in highway construction or other large scale projects, a level with a 500 foot range may be too limited.
  • The Job: If you’re purchasing a rotary laser level with a particular project in mind, you’ll want to consider things like whether the level has 360 degree capability, whether the beam will be sufficiently bright if it’s an outdoor project and whether or not you’d benefit from having wireless remote control of the unit.
  • Battery Life: Some laser levels have relatively short battery life while others, like the Berger RL25HCK feature batteries with an 85 hour life. You may also want to purchase an additional battery or batteries depending on how much you anticipate using the unit in the field.
  • Build Quality: If you primarily work alone on smaller job sites your unit is probably not going to be subjected to much environmental abuse. If, on the other hand you work large-scale commercial jobsites you’re going to want to make sure you purchase a laser level that can take a pounding.
  • Storage Case: When transporting the rotary laser level from shop to jobsite and back, you’ll want to be sure you do so using the storage case built specifically for the device and that that storage case is sturdy and will safeguard the unit if and when it is jostled around in the truck.
  • Warranty: While the best laser levels are built to last, you’ll nonetheless want to be sure you get the most robust warranty you can. Laser levels may look like heavy duty construction equipment but they’re also precision, high-tech devices. You’ll want to be protected. 

Conclusion 

The days of endlessly repositioning the water bubble level in order to keep track of where things are on the jobsite are history. Today’s leading edge builders use leading edge equipment like rotating laser levels to achieve pinpoint accuracy in every aspect of the finished product. We hope you found these self leveling rotary laser level reviews helpful.
