Best Transit Levels For Surveying

Whether you’re taking a train, a bus, or a car, having access to the best transit levels can make your journey much more enjoyable. To help you find the perfect transit level for your needs, we’ve compiled a list of the 12 best transit levels.

1. David White LT6-900 Meridian 22X Optical Level-Transit – Best For Beginners

First up on the list is the David White LT6-900 Meridian Transit. The easy-to-use transit level is one of the more suitable products for those who want something that’s simple and pocket-friendly. With a lightweight design and sturdy frame, the David White LT6-900 performs pretty well for its price.

First things first, the positive customer reviews helped us put our confidence in this transit level. The David White LT6-900 Meridian Transit works accurately for both simple home improvement and large-scale survey tasks. Affordability and convenience make this transit level worth considering, especially for beginners.

The 22x optical zoom is a highlight and provides a magnified and crisp view to a distance of up to 200 feet. With a bit of defocusing, the optical instrument helps to render a more unobstructed view of the area, it measures horizontal and vertical angles seamlessly. In addition to the powerful zoom, its built-in sunshades helped us to obtain better sightings.

As far as measurement is concerned, the horizontal circle located at the bottom of the transit level has single-degree gradients for making minute estimations. Along with the gradients, the horizontal locks and tangent screws work in tandem to give the user full control to make accurate measurements.

The readout dial does not come with a lock, which means that even the slightest disturbance caused to the dial can show inaccurate readings. Similarly, the vertical tangent or angle needs to be adjusted to derive correct measurements. But these are far from deal-breakers, in our humble opinion!

Magnification: 22X |
Accuracy: +/- 1/4″ |
Weight: 14 lbs |
Tripod Compatibility: Yes |
Dimensions: 13.2 x 7.5 x 7.5 in

2. NWI NSLP500B Siteline Transit Level – Best For Basic Survey Needs

The next product on our list is the NWI NSLP500B Siteline Transit Level. Along with a tripod, plumb bob, and robust aluminum rod, the NWI Siteline is a complete and practical measurement kit for all the on-site construction needs, lines, horizontal and vertical angles, you name it! Modestly priced, this transit level is both professional and convenient.

For its affordable price, the NWI NSLP500B Siteline Transit Level seems to be a fitting choice for basic survey needs. We availed its services for a basic home construction job, but the transit level should also work well for farming and agricultural projects. 

Similar to the David White LT6-900 Meridian Transit, this transit level also has a leveling accuracy range of 0.25 per inch per 100 feet. Despite having a 20x optical zoom, it provides a viewing range of above 200 feet which is really impressive.

What appealed to us the most is the quality of the supporting gears. The tripod and professional-grade aluminum rod really add value to the transit level, and are not included only for the sake of it. Also, the NWI NSLP500B Siteline Transit Level does not compromise on portability and ease of set-up.

Though the optical instrument comes with an impressive viewing range, we felt that the quality of the 20x telescope lens is below par. A spotting scope may well be used to improve visibility, but we’d prefer a superior lens any day.

Magnification: 22X |

With a robust design and high-power telescope, it’s worth your consideration.

The high customer ratings are a testimony to the optical instrument’s efficiency in delivering professional-level tasks. Though the 22x optical magnification works for a range of 20 feet, it also comes with a special short-distance 4.5 feet focus range for enhanced precision (required for smaller projects).

What compelled us to try out the AdirPro22x Automatic Transit Level was its aircraft-grade aluminum telescope. Aided by an achromatic-coated lens and built-in sunshades, the telescope cuts out glare to produce clear and crisp images, even when operated on the highest magnification setting.

The clamps and tangent ensured that we could quickly focus the scope on the target. Besides, the siding lock levers made it super simple for us to mount the telescope on the tripod.

Having praised it for being the ‘professional one’, we would’ve loved a simpler instruction manual for users without prior experience of handling transit levels. The perfectionist in you may be a tad bit disappointed, given the absence of clear degree points.

Magnification: 22X |
Accuracy: +/- 1/4″ |
Weight: 8 lbs |
Tripod Compatibility: Yes |
Dimensions: 6.2 x 6.2 x 9.8 in

4. SitePro 25-TL20X 20-Power Transit Level – Best For Small-Scale Construction

The next measurement instrument on this list is the SitePro 25-TL20X 20-Power Transit Level. Easy, affordable, and with a decent working range, this transit level is a solution to essential surveying and leveling needs. Given its price, the unit appears sturdy for everyday use.

Our search for an instrument that works for a primary survey and leveling led us to this transit level, and we are not disappointed about it. The 20x optical magnification delivers clear sightings for its mid-level 200 feet work range. A built-in sunshade, much like the David White LT6-900 Meridian Transit, helps the viewing process.

Despite having a simple design, the transit level does not forgo the other important aspects like clamps and tangents for durability. For its modest price, the instrument does a good job of working for both horizontal and vertical applications.

We were also impressed with the precision of the transit level, especially the telescope, which was able to render a very clear and close focus. In addition, the overall design was sturdy enough to tolerate moderate adversities of daily work.

The horizontal circle at the base is not as accurate as we would have liked it to be. Similarly, the absence of a vernier scale makes it difficult for the user to accurately read the measurements of the horizontal circle.

Magnification: 20X |
Accuracy: +/- 3/16″ |
Weight: 7.8 lbs |
Tripod Compatibility: Yes |
Dimensions: 14 x 8 x 8 in

5. Johnson Level & Tool 40-6912 22X Builders Level Transit System – Best Versatility

For the next instrument on this list, we have the Johnson Level & Tool 22x Builder’s Level Transit. The flexible yet compact design of this transit level system can cater to the construction needs of a wide variety of spaces, like patios, driveways, and streets.

Apart from its capability to work for a range of spaces, we were happy to avail both the horizontal and vertical applications for the price. The horizontal circle has a vernier scale and reads to single-degree precision. Both the horizontal circle and vertical arc are fastened by horizontal screws, and vertical lock and screws, respectively.

The mounted telescope comes with an easy-to-operate leveling vial for movement control and precision reading. Along with a built-in sunshade to improve image quality, the large-sized lock screws make this transit level user-friendly and convenient.

Straight off the bat, we really liked the optical instrument’s ability to work for the various construction needs- everything from surveying to landscaping. The 26x optical magnification is a nice compromise between the more powerful and less competent scopes. Also, an optical plummet with 1.5x magnification that replaces the more commonly found plumb bob does work fine to improve visibility.

To deliver on its claim of being reliable, the David White Universal Transit Level has included features for smooth operation. For instance, a wide ball-bearing aided center helped us to move the level without any jerk and also assisted the alignment control.

Both the horizontal circle and vertical arc are secured by a set of locks and tangents,. This is a good set-up to enhance accurate measurements since there are fewer chances of them being off-position.

We did experience some level of difficulty in operating the locks, as compared to transit levels of other brands. Also, users who generally work with a plumb bob may find the optical plummet to be a missed fit.

As the name rightly suggests, the NWI NCLP32 32X Contractors Automatic Transit Level is a sought-after measuring tool for contractors and independent workers. The package is affordable and aids precision surveying.

We really liked how the performance does full justice to its name. The 32x optical zoom works great for the 400 feet working range and exhibits clear sighting. If you plan on buying a product for surveying larger spaces, then the NWI 32X Automatic Transit Level should be considered

This automatic transit level has an accuracy of 0.0625 per 250 feet, making it one of the most accurate optical instruments in the price range. Though we tried the instrument for measuring distance, it is also commonly used for calculating horizontal angles and checking elevations.

Much like the NWI Siteline Transit, this one too comes in a package, with a contractor’s tripod, aluminum rod, plumb bob, and carrying case. Again, the supporting tools enhance the overall value and efficiency of the transit level.

Despite having the utility for more than one task on hand, this automatic transit level is not at all suitable for vertical applications. Also, you need to carry the tripod and rod separately, as the case is just about the right size to carry the optical instrument.

Magnification: 32X |
Accuracy: +/- 1/16″ |
Weight: 8.5 lbs |
Tripod Compatibility: Yes |
Dimensions: 7 x 7 x 10.5 in

8. Bosch 26X Automatic Optical Level GOL26

A perfect combination of portability and power, the Bosh 26x Automatic Optical Transit Level has a working range of up to 330 feet. With an affordable price tag, this transit level comes with multiple features that simplify distance and angle measurement.

Having dealt with a number of transit levels that work only for horizontal applications, we were relieved to find a product for both our horizontal and vertical measurement needs. The 26x optical magnification delivers clear and bright images for its wide 330 feet working range.

To facilitate portability, the self-leveling compensator works together with the automatic transport lock system for protecting the unit’s pendulum against damage and loss of calibration. Similar to the Ac-2S Automatic 24x Transit Level, a magnetic dampening system in place ensures the instrument’s stability on uneven job terrains.

The Bosch 26x Automatic Optical Transit Level also features a bubble vial and 90-degree glass prism to reduce the set-up time. We were impressed with the measuring instrument’s commitment to being travel-friendly and ease of use.

We spent a hefty amount of time figuring out how to use the self-leveling compensator.  In addition, the instrument’s portability is not synonymous with durability, as we felt it might not be able to withstand the daily wear and tear of long-term jobs.

Magnification: 26X |
Accuracy: +/- 1/16″ |
Weight: 2.2 lbs |
Tripod Compatibility: Yes |
Dimensions: 6.5 x 4.2 x 4.6 in

With accurate measurement facilities and an easy set-up, this transit level does not burn a hole in your pocket.

Dewalt has a reputation for delivering high-quality products, and the DW092PK 20X Transit Level is no exception. Though the working range of 200 feet appeared a bit modest to us, the 20x optical magnification produced the perfect level of clarity for our sightings.

This measuring instrument did also surprise us with its dual application for horizontal and vertical measurement- thanks to its 360-degree horizontal circle, equipped with a vernier scale. While moving the scope, we did not face any significant mobility issues, which is a big positive for an inexpensive instrument like this.

The tripod included in the package is professional-grade and sturdy. Also, it has a heavy-duty leveling base for a smooth and quick set-up on different terrains.

Lifting the transit level is one really tough job, as it does not have a lightweight design. Hence, portability becomes a concern. But given the plethora of other nifty features, it has to offer, this hardly comes across as a deal-breaker.

Magnification: 20X |

Dimensions: 18.6 x 8.8 x 6.9 in

10. Bosch Optical Level Kit

From the house of Bosch, the next product is an optical kit with a self-leveling 32x magnification and a magnetic dampening system for easy use and quick setup. A 32x zoom has an impressive work range of up to 330 feet-all this is packed in a design that is both water and dust resistant.

To begin with, a closer look at the transit level’s design revealed the carefully thought-out approach to make it durable for everyday operation. Plastic over-mold in vital areas with a metal casing and 1P54 protection work together to defend the instrument against dust particles and sudden water splashes.

For visibility, we had the transit level’s 32x magnification with a working range of 330 feet to produce sharp and bright sightings. Much like the Bosch 26x Automatic Transit Level, the self-leveling system functions to stabilize both the horizontal and vertical line of sight.

When you need a quick and reliable set-up for taking accurate measurements, the magnetic dampening system comes to the rescue and ensures minimum distortions for smooth operation. Also, the transport lock works to enhance portability.

Looking through the telescope can be a bit confusing, especially with the serial order of correcting the zoom focus first and then adjusting the fine focus. Then again, that’s only till you get used to it, after which it will not be a significant inconvenience.

Magnification: 22X |
Accuracy: +/- 1/8″ |
Weight: 5.5 lbs |
Tripod Compatibility: Yes |
Dimensions: 14 x 5.3 x 4.9 in

This member of the N500 series is efficient and accurate, but we wished that it was self-leveling, considering that the price is a bit on the higher side.

Magnification: 24X |
Accuracy: +/- 1/16″ |
Weight: 4.4 lbs |
Tripod Compatibility: Yes |
Dimensions: 5.5 x 5.1 x 8.9 in

Buying Guide For The Best Transit Levels for Surveying

No matter how big or small the construction is, precise measurement and leveling are imperative for building the perfect establishment. If you do not have the right instrument for the purpose, then getting those much-needed measurements can be a tedious task.

To choose the right transit level, it is crucial to determine the purpose for buying one. After going through the features and abilities of the various products available out there, we decided to list the significant factors to be considered before purchasing a transit level.

We bring to you the characteristic features that must be kept in mind before you shell out those hard-earned bucks. Read on to know more….

Types of Transit Levels for Surveying

Transit levels have mainly three categories – automatic, speed line, and universal. 

The automatic transit levels are built in a way to help users get the most accurate measurement, irrespective of the uneven terrain or harsh environment. With traditional transit levels, the graduated vials mostly produce slightly ‘off’ measurements when working in unfavorable conditions. 

Automatic transit levels, on the other hand, use magnetic-dampened compensators for securing the correct line of sight. We recommend an automatic transit level if you need to survey uneven terrains, or you have to work on a large-scale construction project.

Speed line transit levels are also durable for bumpy surfaces and ground vibrations. However, they are more productive when it comes to measuring rough angles. In addition, they are a perfect fit for fine-tuning measurements. 

Many such models use multiple elements like vertical arcs, horizontal circles, and tangents for enhanced stability and convenience. We recommend a speed line transit if you want an instrument that is more advanced and easy to use.

Lastly, universal transit levels are the perfect fit for large-scale constructions or survey work that requires horizontal or vertical sighting.

Transit Level Kit/Package

Most transit levels come within a package that includes other supporting tools like a tripod measuring rod, and also a carrying case. If you do not want the hassle of buying things separately, we recommend going for a kit or package with the related must-haves.

Portability

There are but a few transit levels which are bulky yet extremely reliable. If you do not need to carry the instrument from one place to another, you might opt for one such model. However, a lot of lightweight designs for accurate and quick measurement and leveling are available for purchase.

Magnification

The range area of your surveying and/or leveling plays a crucial factor in determining the transit level. For example, if you want an instrument with a narrower field of view for closer terrains, you can opt for a transit level with 32x zoom. Such models are usually preferred by contractors and building professionals.

Standard range surveying or leveling works usually require a 26x or 28x optical zoom. If you are a beginner or plan to use a transit level for basic everyday tasks, you may well opt for such a measuring instrument that has a 26x or 28x scope.

In addition, you can also consider such units that have a diopter for better and precise focus.

Transit Levels Materials

No one wants to invest in a transit level that cannot withstand the adversities of construction work. While some models are resistant to dust, a lot of them are also made to be water-resistant. Ideally, a model that is both water-proof and dust resistant should be considered for purchase.

If the construction site has a lot of ground vibrations, we recommend a vibration-shock-proof model. For heavy-duty construction sites that are bound to have a lot of wear and tear, we will suggest a model that has a metallic body.

The Convenience of the Transit Levels 

An instruction manual accompanies most of the transit levels available in the market today to guide the user in operating the instrument. However, some models which do not have an instruction guide are generally easy to operate. On the other hand, other models may have a manual but can still be difficult to understand.

If you are a beginner or do not want to spend a lot of time figuring out the setup and operation, you can buy a more user-friendly model. Complicated transit levels are more suitable for professional-grade work, or for users who have prior experience in handling one.

Additional Features of Transit Levels 

Apart from all the necessary elements that are needed to carry out accurate measurement and leveling, many other features also assist the transit levels. One such common feature is the presence of in-built sunshades, that facilitate clear sightings for outdoor projects. Outdoor construction-related surveys and leveling can be executed better with such features.

Most transit levels offer such additional features at an affordable price. We recommend such transit levels that employ mechanisms to improve visibility, leveling, and accurate measuring.

Can transit levels be used for measuring angles and slopes?

Yes, transit levels can be used to measure both vertical and horizontal angles, as well as slopes and grades. However, some models may have limitations when it comes to measuring steeper angles or longer distances.

Can transit levels be calibrated?

Yes, transit levels can be calibrated to ensure they are accurate. It is important to follow the manufacturer’s instructions for calibration and to have the level checked periodically by a qualified technician.

How accurate are transit levels?

The accuracy of a transit level depends on the model and the manufacturer. Some models have a range of accuracy between 1/16 to 1/4 inch at 100 feet, while others are more precise and can provide accuracy up to 1/16 inch at 200 feet.

Can transit levels be used in low-light conditions?

Yes, some transit levels come equipped with illuminated reticles or built-in lights that make it possible to use them in low-light conditions.

What is the difference between an optical and a digital transit level?

An optical transit level uses a telescope and an adjustable bubble level to measure angles and distances, while a digital transit level uses electronic sensors to measure these same parameters. Both types have their advantages and disadvantages, and the choice between them depends on your specific needs and preferences.

Conclusion

If not for transit levels, carrying out construction-related measurements would have been extremely laborious.

Our carefully curated list of the 12 best transit levels ticks the boxes of affordability, clear sightings, and of course, accuracy. Before we call it a day, let us summarize our findings for you.

The David White LT6-900 Meridian Transit and NWI NSLP500B Siteline Transit Level are both affordable and user-friendly. AdirPro 22X Automatic Speed Line Optical Transit Level, on the other hand, is a professional favorite.
