Before you buy: 11 Things to consider when purchasing laser level

Below are factors that you should consider when shopping for a laser level:

1. Visibility Range and Accuracy

The accuracy of a laser level describes the leveling of a given work surface expressed in a fraction of an inch. For instance, a laser level instrument with an accuracy rating such as +5/16 inch is considered less accurate in comparison with a +⅛ inch instrument. In other words, the more accurate your laser level is the better it serves its intended purpose.

In the meantime, the visibility range of a laser level describes the distance with which you can see the laser with your own naked eyes. Therefore, the longer the visibility range of your laser level. The larger work surface you can work with.

Some of the Class II Laser diodes are bright enough to be seen at a distance of up to 50 feet when you are working indoors. So, 50 feet is just enough for you when working on a small scale or mid-scale construction project. For large-scale projects, you will require higher visibility laser level instruments.

2. The Color of the Laser Beam

When shopping for your laser level, you must consider the color that will work best for you. In this regard, there are two color options to choose from. These colors are green and red. Whether you settle for green or red lasers, make sure that your choice goes hand in hand with where you are going to use your laser level.

For outdoor construction projects, green lasers are the most preferred. This is because they are more visible in bright sunlight than the red lasers. On the other hand, the red lasers are quite effective when you are working indoors because they are quite perfect in low light situations such as those found indoors.

3. The Source of Power

All the laser levels that we have covered so far operate with the help of certain types of battery power. Most of the batteries used in these tools range from any type of AA batteries all the way to rechargeable ones.

In this case, you can rely on standard batteries because they are relatively cheap and easy to switch out. On the flip side, these batteries are not long-lasting compared to rechargeable types. In addition to that, you can only use them once.

Unlike other types of batteries, the rechargeable batteries are more expensive than standard batteries. The reason why they are costly is that you can use them over and over again provided that you recharge them when the power runs out. The only major setback with these batteries is their charging time which may delay the completion of your work.

4. Battery Life

The battery life is one of the key factors that you should consider when buying your laser level. The overall battery life of your choice will depend solely on the type of the battery itself and how often you are going to use your laser level.

As stated earlier, the rechargeable batteries are more likely to last longer than other types of batteries (standard AAA and AA). Besides, you can recharge them when the power reduces.

Unfortunately, rechargeable batteries take some time to charge. When they run out during the working hours, you cannot swap them out, in the same way, you will do for standard batteries. This is one major setback of relying on rechargeable batteries to operate your laser level.

Another factor that can affect battery life is how frequently you will be using your laser level. If you know that you will be using the level constantly, then make sure that you get batteries that will sustain you for long. For that reason, you should consider purchasing rechargeable batteries because you can charge them anytime they run out in addition to saving you some money.

But if you are going to use your laser level occasionally, you may opt for standard batteries. This makes more sense than using costly rechargeable batteries when you are not using your level consistently.

5. Number of Dots or Beams

The type of laser level you want to buy will depend on the kind of project you are about to undertake. If your project is advanced, you will require a laser level that is a bit advanced. This means you will need a laser instrument that will provide you more dots or beams when pointing places for reference.

But for a simple project, you won’t need to bother yourself searching for an advanced laser level. Instead, you will settle for a basic type to save you some money in the process.

6. Manual-Leveling Versus Automatic/Self-Leveling Lasers

A few laser levels come as manual leveling, meaning that you need to observe the behavior of the bubble vital to know if the entire unit is accurately leveled.

To operate a manual level unit, you need to make some adjustments using thumbscrews on the unit. As you may have guessed right, this process is tedious and cumbersome if you are not experienced enough in using this type of equipment.

Self-leveling laser levels are somehow different such that they come with an internal pendulum designed to do the leveling on its own. As the name suggests, this piece of equipment levels itself automatically to up 5 degrees regardless of whether the surface is vertical or horizontal. With this type of laser leveling, provided that the inclination falls within the 5-degree mark, you can use it as your reference point.

In case of an error, the out of level indicator will blink to alert you even before you take any further step.

Both types of laser levels have advantages and disadvantages that make them unique tools. First, both types are very useful in one way or the other. The only major exception is reflected in the self-leveling lasers which save you time and are more accurate.

7. Horizontal Versus Dual Beam Laser Levels

Horizontal Lasers are known to emit only laser beams. These devices play a critical role in checking floor leveling. Horizontal laser levels have the capacity to show or display irregularities on any work surface. But their applications are limited even though they are a little bit cheaper than the dual-beam lasers.

When it comes to the dual-beam lasers, the situation is different. These devices emit two beams whereby one is vertical and the other is horizontal. Most of these instruments come with individual buttons where each of these buttons is designed to control the beams separately.

For that reason, the dual-beam laser levels allow you to experience greater flexibility while working on different surfaces. Also, the dual-beam laser levels are used simultaneously as level and plumb reference lines. If you are planning to throw lines onto your walls and floors at 90 degrees, dual beam lasers will help you achieve this feat.

Quite a number of dual beam lasers are capable of projecting cross lines rather than individual vertical and horizontal lines. These models of dual-beam laser levels are suitable for installing bigger wall fixtures and partitions or drop ceilings.

Rotary lasers are similar to dual-beam lasers in such a way that one beam comes out as a plumb up dot on your ceiling while the other is displayed as a horizontal line around your room. This type of laser level is ideal for checking the leveling of your wall or when installing the wainscoting/cabinetry that is more likely to span your entire room.

8. Laser Detectors/Laser Receivers

Laser detectors have two major uses; to extend the laser level’s working range and to enable your laser level to be used in bright light or outdoor conditions. Most laser detectors emit certain sounds to help you get the required level.

A fast tone is meant for moving the detector/receiver down. The slow tone for moving it up and a steady tone to show that you are at the required level.

The decision to buy a laser receiver depends on various factors, key among them being the types of applications you want to use it for. If you are looking forward to using it outdoors, then the laser detector may not be of any importance to you.

It’s wise to know that not every laser level is compatible with all laser detectors. If you are planning to purchase detectors for your future projects, you must check all the specifications before you make your final decision.

9. IP Rating

IP refers to “Ingress Protection”. This is the quality of a product in terms of sealing and effectiveness in protecting it against foreign objects such as water and dirt.

When looking at the IP rating, you need to be fully aware of some digits. The first digit you will ever come across on the IP rating is the actual size of an object that is likely to intrude on the product you want to buy. The second digit denotes the capacity or ability of the laser level to protect against moisture.

10. Mounting Threads

Mounting threads play a significant role in certain applications. This ensures that the laser level remains stable throughout. For instance, you can keep the beams to a specific height or certain position with the help of the mounting thread.

Most laser levels are designed specifically for standard tripods. Others need a special mounting device. This is where the mounting thread comes in handy to make your work easier.

11. The Specific Purpose of the Laser Level

What you want to do with your laser level is the most important factor to consider when shopping for this equipment. Laser levels come at different designs, models, sizes, and prices. These specifications make each equipment unique in the way with which you are going to use it. Each laser level is used for specific applications.

Here are common types of laser levels that you are likely to come across on the market today:

  • Single Beam Lasers: Ideal for checking leveling on floors and walls before the heating vents or tiles are installed.
  • Dual Beam Lasers-Simple Vertical and Horizontal Lasers: Suitable for transferring points from the floor to the ceiling. Also, you can use them when performing easy installations of lighting.
  • Dual Beam Lasers-Cross Line Lasers: Designed for layout and installation of plumbing and electrical systems, doors, walls and fitting of tiles onto walls. Also, these laser levels are applicable in the installation of long rows of wall fittings as well as cabinetry.
  • 3-Beam Lasers/Layout Lasers: This type of laser level comes with all the benefits of vertical and horizontal lasers including a third plumb line checks. This type of laser level is suitable for cabinetry and other jobs that require lots of 45 degrees and 90 degrees measurements.
  • Rotary Lasers or Line Lasers with Laser Detectors: These equipment are meant for job sites found in well-lit locations as well as those measuring more than 50 feet.

What’s a Laser Level?

As you may have guessed, a laser level is simply a tool designed to help you achieve the highest precision when you place it on a horizontal or vertical surface.

To make it more clear for you, this tool uses electric power to project either green or red beam horizontally or vertically or even both around itself. This beam directs you to level all sides equally when you place it on a flat surface.

On the other hand, if you put the laser level right at the center of your room, it will project horizontal lines on the walls. These lines will be equidistant or rather have equal length/distance from the walls and the floor where you placed your tool.

As you may have expected, this instrument has several applications such as leveling and squaring. Also, this tool is vital in construction and carpentry work where leveling is crucial.

In other words, a laser level plays a significant role in providing you with accurate levels of a given surface such as walls, floors or pathways among others. This versatile tool saves you a lot of time by allowing you to carry out as many tasks as possible.

How Do Laser Levels Work?

Laser levels have been carefully designed to be effective, efficient and easy to use. With a variety of designs on the market today, there is a style that fits anyone and any application. That explains why different models of laser levels have been designed for specific functions.

Nevertheless, every laser level comprises of two major components that make it suitable for leveling and alignment applications. The first component is the laser plus leveling base that is capable of being mounted on the wall, attached to the tripod or sit on the floor. The base plays a critical role when it comes to projecting the light (red or green beam) at a specific height.

The second component is the leveling mechanism. This part comes as a bubble vial or simply a pendulum with magnets and electronic sensors (we will discuss the differences between these mechanisms later).

Another component of great importance on a laser level is the case or closure. This is usually made of long-lasting metal or plastic for sturdy performance during the operation.

Laser levels are quite fascinating tools. They usually find “level” in many different ways much to your amazement. For instance, manual laser levels use the traditional way of determining different levels on different surfaces. This type of laser enables you to align the bubble inside the vial by simply turning the knob or repositioning the level.

From this explanation, you can tell that the manual laser levels are designed for typical DIY projects. Most importantly, these laser levels are affordable and require less power to operate compared to the self-leveling units.

For self-leveling units, you will realize that almost everything is different from the manual laser levels. To begin with, instruments in this category boast a greater degree of precision or accuracy. As a matter of fact, they work best when you place them on a close to level surface as determined by you.

Just like the manual laser levels, self-leveling units allow you to use the bubble vial in order to level them before their self-leveling mechanism perfects the whole leveling process.

One thing you need to know about this unit is that the laser component hangs more or less the same as the pendulum while inside the level. Gravity and magnets work simultaneously to keep the pendulum still while the beam is being projected through the light or prism.

Quite a number of laser levels come fully equipped with components that allow them to achieve the required levels. These components are made up of several electronic self-leveling sensors that promote accuracy as well as reliability. The sensors are usually ideal when working on the busy outdoor construction site.

When working indoors, the self-leveling mechanism inside the laser levels helps a lot in saving time and increasing reliability.

Basically, this is how the laser levels work regardless of which leveling mechanisms they are using. Lucky for you, these tools are carefully made to make your work effortless.

  • Select the filter lens that matches the information above. Make sure you select the one that provides the highest level of visibility.
  • Look for a frame that suits you. Select a fit-over frame for prescription options.

What Can You Do With A Laser Level?

As the advancement in technology takes place over the years, laser levels get smaller, accurate, easy to use and affordable. That is the reason most construction workers use these tools to make their work easy and save time.

Today, laser levels are used in large construction projects in different parts of the world. Also, this vital tool is popular among DIYs who perform different tasks on their own.

As more and more people become familiar with this type of instrument, they tend to find new ways to use it to make their work perfect and less stressful.

Generally speaking, laser levels are important tools in layout projects. Actually, such projects require high accuracy and the only way of achieving this feat is by use of instruments that offer very high precision. And this is where laser levels come in to save the situation.

Common applications that require the use of laser levels include installation of sewer pipes, ceiling tiles and chair railings.

Some of the indoor installations/applications that require laser levels:

  1. Level floors that need a single line laser light.
  2. To keep the walls perpendicular or straight with the help of a 3-beam line laser.
  3. Useful in the installations of ceiling drops.

  4. In the preparation of a new layout for the construction site
  5. Checking the sight elevation to improve drainage installation
  6. Also, applicable in contour farming especially for better irrigation

Types of Best laser levels

Laser levels come in two major types; prismatic and rotary. Let’s look at each type in detail so you may know which one to use for specific applications.

  • Dot Lasers

    They are are designed to project five beams of light to help you establish a point with 90 degrees reference between the floor and ceiling.

  • Line Laser Levels

    They are capable of projecting a single beam of light at 180 degrees vertically and horizontally. This way, you can easily establish the plane on the surface you are working on.

  • Rotary Laser Levels

    This type of laser levels are only suitable for construction projects. This is because they use light-emitting diodes (LEDs) with extra larger rotational speed. Their range goes all the way to 500m.

    This feature makes rotary laser levels to have numerous advantages such as greater accuracy and scanning of surfaces of different thicknesses. That’s why rotary laser levels are more expensive than the prismatic laser levels.

    When shopping for any of these instruments, you should pay attention to their point levels of the visible rays. Most of these tools provide only a single point on any reflective surface.

  • Prismatic Laser Levels

    We start with the prismatic laser levels. These tools have their own distinctive designs that set them apart from the rest. Their design is made up of a few layers including their light which is created using a special prism.

    In simple terms, the light is emitted through the prism horizontally and vertically. As a result, the light creates two powerful beams that form a cross together. However, you can enable or disable the two light beams to suit your different needs. Even though the range of the light is small, you are rest assured that it’s perfect for any project around your house.

  • Alignment Light Beam

    You can achieve this type of alignment either manually or automatically. This alignment is important at the start of the level. Some laser levels are designed to manually align or level the bubble. Such tools are built within an enclosure. This type of alignment requires more effort and time.

  • Self-Leveling Pendulum Level:

    This comes with a set design pendulum including its weight level light-emitting diodes (LEDs) that work horizontally and vertically. These levels can turn on their off post for 30 minutes of work. At the same time, they can create up to five simultaneous beams for different places. In this case, there is minimal chance of creating errors.

  • Self-Leveling Electronic Levels

    From the users’ reviews, self-leveling electronic levels have the highest accuracy. This is because their levels of errors are minimal regardless of the distance the beam covers. Besides, their complex leveling mechanism is always ready to work immediately.

  • Inexpensive Torpedo Level

    This is suitable when working around the house. Due to their small size, you can easily carry them in your tool belt. To get the best result, the bubble must be centrally aligned with the vial. This alignment will make the level to project a laser dot or line.

  • Self-levelling Cross Line Laser

    Versatile and easy to use, the self-leveling cross-line laser is just right for you if you are working on different types of leveling or plumbing tasks.

  • Laser Level Square

    This is perfect for laying out tiles at right angles (90 degrees) corners for sheds. Laser level square projects two perpendicular lines and is suitable for both outdoor and indoor projects.

  • 3 or 5-Point Self-leveling laser

    This type of laser is designed to help you transfer certain points from the floors to the ceiling. You can place this type of laser on a tripod when marking the level line.

  • Auto-level Rotary Laser

    It is suitable for outdoor tasks or projects involving fountains and decks. This type of laser level includes an elevation, a tripod, and a laser detector to enable you to use this tool in bright sunlight.

  • Laser Intensity

    It is measured in milliwatts (simply the mW) and it is a determinant of the laser’s power.

Most laser levels use Class IIIA lasers but different levels exist.

  • Class I Laser: With this type of laser, the beam alone can cause serious damage to your eyes if you look at it using a magnifying glass. Otherwise, it doesn’t have any known radiation effects. The Class I Laser is commonly used in CD players, product scanners and laser printers.
  • Class II Laser: Just like the Class I Laser, this one is not damaging unless you observe it under magnification or when you direct it at someone else’s eyes. The Class II Laser is used in laser pointers.
  • Class IIIA Laser: This type of laser is useful in most laser levels. It is more likely to cause spot blindness or other eye injuries.
  • Class IIIB Laser: This is useful in light shows or lighting effects. This class of laser can damage your eyes or burn your skin.
  • Class IV Laser: This is applicable in burning and cutting tools. It is also harmful to your eyes, can burn your skin and cause fires as well.

    With this information at your fingertips, you need to decide what you can use the laser before choosing it. Most laser levels are equipped with Class IIIA which is less harmful compared to other classes.

Accessories that Come with a Laser Level

Most laser levels are used outside their boxes. All you need to do is to press the button. But the best laser levels come fully equipped with mounting hardware among other accessories.

For the best performance of your laser level, you need to purchase the following items:

  • Tripods: to keep your laser level stable and in one position.
  • Laser detectors: for outdoor use of your laser level. This also increases the range.
  • Leveling staff and rods: for easier leveling of the device.

How to Set Up the Laser Level?

  1. One of the things you are supposed to do first before using the laser level is to set up everything on an even/flat surface. You may need a tripod for this task.
  2. When setting up a manual laser level, ensure that its bubbles are in the middle or at the correct level. If not, just turn the screws close to the vial to get the level. Then switch on the level to make it ready for use.
  3. If it is a self-leveling laser, the setting is somehow different. Here you will take a few seconds to allow it to level on its own. A few units of self-leveling lasers emit a blinking ray of light when they get out of level. As such, you will have to adjust the whole unit, turn it on and use it.
  4. In absence of a wall where the laser beam should reflect on, you may reach out for the laser detector to search for the beam. However, check the manual to know how the laser detector signals the leveling.

How to Use Your Laser Level?

  1. Set up your laser level on the flat surface or tripod.
  2. If you are using a manual laser level, the bubble vial must show the level. Use the small screws located next to the vial and adjust them to make the vial show the level.
  3. Switch on your laser level.
  4. If you are working with the self-leveling laser level then you should give it a little more time to let self-level on its own.
  5. This unit emits laser beams that show the level on the wall or across the outdoor workspace. But this depends on the model of your laser level-it could be multiple lines, a dot or rotary laser indicating the level at 360 degrees vertically or horizontally.
  6. You may also use the laser detector to help you intercept the laser beam where there is no wall to show it.
  7. Connect the laser detector to the measuring rod.
  8. Adjust the laser receiver/detector up and down until you hear a beeping sound. The sound is meant to help you know that that the detector is in line with the laser.
  9. At this stage, you must have found the level to secure the detector to the rod. Proceed to make measurements as required.

How to Use Your Laser Level Outdoors?

  1. First, you should wear tinted glasses or goggles that come with the laser level kit. The goggles are necessary to allow you to see the laser beam while working outdoors.
  2. Place your laser level on a tripod before switching it on.
  3. Set to aim at the spot you want to determine the readings. Once you find the right spot lock the laser level into the right position.
  4. Take the laser detector to a place you want to take the readings. You may either use the magnet that comes as part of the laser level unit or place it strategically at the same level as your laser level. But a second tripod would be a better option in this case.
  5. Move the laser slowly and gently until it aligns with the laser beam from the level. After finding the beam, make sure that you lock the detector in position or make it steady if it is not on an even surface or attached by the magnet.
  6. Use the receiver and level to get the alignment in place or in a state of the level you want to achieve.

How to Use a Laser Level to Hang Pictures?

  1. Work out the right height for your picture frame.
  2. Draw a mark or spot anywhere at this predetermined height.
  3. Switch on your laser level to line up it horizontally with the mark on the wall.
  4. Make some adjustments on the laser to make the bubble sit between the vial and black lines by simply pivoting it around the point where the laser and the mark intersect.
  5. Once your laser is at the right level with the mark on the wall, attach it as soon as possible. Your level may require suction cups or putty to stay in position.
  6. Take the measurements of the distance between the top side of the picture-frame and its unique hanging mechanism.
  7. Also, measure the distance on the wall starting from the laser moving down to where the mechanism meets the wall.
  8. Make a mark.
  9. Then punch the nail right where you had placed the mark.
  10. Hang the picture frame on the nail and align it using your laser level.

How to Use a Laser Level to Level Ground?

  1. Set up the laser level on a tripod on stable ground.
  2. Turn on the laser level.
  3. Give it time to self-level.
  4. Identify a point on the ground at your desired height.
  5. Attach the laser detector to a measuring rod and place the rod at this point.
  6. Adjust the laser detector up and down. When you hear beeping, you have found level.
  7. Tighten the detector to the pole.
  8. The bottom of the rod is your desired ground height.
  9. Find another spot on the ground and find the height where the detector intercepts the laser.
  10. Mark the height by making a mark on a stick or building up a pile of dirt up to the desired height.
  11. Repeat this process until you have enough reference points to fill the area completely.

How to Set Grade with a Laser Level?

  1. Set your laser level on a strong tripod and a firm ground. Make sure that the tripod is stable.
  2. Switch on the laser level and let it self-level.
  3. Find the initial height of the grade where the pitch (of the grade) slopes down gently.
  4. Put the bottom of the leveling rod at the height of your choice.
  5. Make a few adjustments on the laser to achieve the right level.
  6. Secure the detector.
  7. Identify the correct amount of fall starting from the top of the grade moving to the bottom.
  8. Move the laser receiver up the rod (10 inches) and secure it.
  9. Take a walk to where you expect the bottom of the grade to be.
  10. Use the laser detector to find the level. In this case, you must lift the rod or just dig a little bit into the ground.
  11. At this stage, you should know that the bottom side of the leveling indicates the bottom area of the grade.
  12. Mark the spot using a stick. Insert the stick in the ground to display the expected height.

How to Using Laser Level To Install Wall Tiles?

In most homes, floor to ceiling heights differs greatly from one room to another. This implies that using the floor as your base for installing wall tiles is not a good idea. Therefore, you should strive to get the first row of tiles by considering the following steps:

  1. Identify an appropriate point on your wall (a few inches away), making sure that the distance from your wall to this point does not exceed the height of one tile.
  2. Switch on your laser level and align it horizontally as explained in step 1.
  3. Align the end of the 2-inch-wide board with the laser and fix the board on the wall using screws.
  4. Rest the tiles of the first row on top of the 2-inch-wide board to make a perfect level on the first row.
  5. Keep on putting more tiles up to achieve your right height on the wall.
  6. After all the tiles are installed, get rid of the baseboard.
  7. Then custom-cut the tiles at the bottom row to maintain consistency in their alignment.

How to Determine Floor Level?

  1. Start by laying a 4 to 6-foot beam level on the floor. Confirm the bubble located at the horizontal tube within the level is floating between the vertical lines. If you realize that the bubble is not floating between the lines, make some adjustments on the level to make the bubble float as required.
  2. Measure each of the gaps that appear between the level and the floor. If any of the gaps measures less than ⅛ of an inch, you may consider that section of the floor to be accurate. Anything larger than that space calls for drastic measures. In this case, you may pour a self-leveling mortar to level the flooring surface.
  3. Mark all the areas that are higher than ⅛ inch on the floor. Such higher areas require sanding if the floor is made of wood. For the concrete floor, you can do a little bit of grinding to level these sections.
  4. Slide the level on the floor gradually to ensure that all sections of the subfloor are all leveled.

How to Using Laser Levels To Install Ceiling Fixtures?

Ceilings and floors have similar measurements. If you’re installing ceiling fixtures you must start laying them on the floor before transferring them to the ceiling.

Here is how to go about:

  1. Mark the position of the ceiling fixtures on the floor.
  2. Place the laser level on the tripod and switch it on.
  3. Align the downward-pointing laser beam to the center-most part of the fixture (marked on the floor).
  4. Using the upward-pointing beam, mark the exact location on the floor.
  5. While on the floor, take measurements of the length from the points where the ceiling fixture is to be attached to the beam.
  6. Transfer the measurements on the floor to the ceiling.
  7. Hold up your ceiling fixture in readiness for installation.

Frequently Asked Questions

Q: Do you think laser levels are harmful to your eyes?
A: Laser levels use class II diodes. These diodes emit light that is not harmful to your naked eyes. Its beams have low power that cannot cause any damage unless you look straight into the source of the beams.

Q: Which is better, greed or red laser level?
A: One thing you need to know about laser levels is that there is no known difference in accuracy when it comes to green or red laser levels. The main difference is seen in brightness, color, price, battery life, and visibility range. Generally, green laser instruments are quite visible to your eye and have an extended range compared to red lasers. Such differences do not point out that green lasers are superior to red lasers.

Q: Which color laser is recommended when working during the daytime?
A: In daylight, the spot or dot is only visible when you direct a laser beam to a surface. The only visible wavelength or color to your eyes is 532nm green, meaning that you are only able to see green lasers under daylight conditions. Therefore, green lasers are suitable to work with where there is plenty of light or during the day.

Q: What is the difference between red and green lasers?
A: Your eyes (human eye) can see green color better than red especially when it is in the form of light. This is also the case when the green light is emitted at longer distances. When you use both types of laser colors in bright light you will experience difficulties in seeing them unless you use a laser detector.

Q: How does the self-leveling laser level work?
A: This type of laser level works on a very simple principle; first the light finds its way into the compensator located at one end before getting into mirrors or prisms (prisms or mirrors are mounted on a floating platform ). Then the light exits through other prisms and lenses.

Q: What’s a cross-line laser level?
A: This model works by projecting bright crossing vertical and horizontal lines that have an accuracy of ⅛ inch at a height of 30feet. The laser level’s full-time pulse mode lets you use this tool with a detector/receiver to maintain full brightness while extending the laser’s working range to about 165 feet.

Q: What’s the use of a cross-line laser level?
A: A cross-line laser deflects the beam at 180 degrees horizontally, vertically or both. By so doing, this line creates a steady beam that becomes easily visible when working on a surface.

Q: How often should you calibrate your laser level?
A: The first thing you need to do is to buy a laser level that comes with a pre-sale calibration along with an accuracy check. When you use them daily the unit needs to be calibrated once every six months. If you calibrate them once or twice a week, you should do it after one or two years.

Q: Should I check calibration on my own?
A: Yes, you can do it provided that you understand how laser levels work. As such, you can do it by projecting the dot or beam on a wall at approximately 5-10 meters away. Then turn the laser level by 180 degrees to check if it has aligned itself as required.


When it comes to choosing the best laser levels, everything is narrowed down to your needs. The truth of the matter is that these tools are all designed to serve similar tasks but each model differs greatly from the other.
