Best Transit Levels Reviews For 2019

What is a Transit Level?

Transit levels are necessary for identifying contours in the land and surface area used for buildings and construction projects. Builders, architects, civil engineers, and everyday homeowners all use transit levels to measure their work. Specifically, a transit level is a type of optical instrument (such as a telescope) with a built-in leveling tool (like a graduated vial) and base. Workers use transit levels for surveying, building, and finalizing their construction and engineering plans.

 

Why You Need a Transit Level

Transit levels identify the sites on land that need to be evened out or “level off” prior to erecting a building, bridge, or any other type of construction. A transit level is important for checking grades, leveling, and turning angles. The reason you need a transit level (in addition to a standard builder’s level) is that transit levels take more accurate vertical measurements (also known as plumbing or plumb measurements). Whereas a builder’s level focuses primarily on flat or horizontal measurements, a transit level can help provide a more accurate picture with vertical angles.

 

Benefits of Transit Levels

Foremost, transit levels help prevent serious measurement errors in construction. This can help prevent long-term problems (like foundation damage). In this way, the tool may help you save money in the long run.

Other primary benefits of transit levels include the following:

  • Optical magnification typically higher than other leveling tools
  • Helps determine vertical angles and basic grades
  • Ensures accuracy on turning angles
  • Allows you to choose a flexible working range
  • Assists with checking alignment and plumb during construction jobs
  • Helps determine slope and other steep jobs (suitable for vertical alignment tasks)

 

Guide To The Best Transit Levels

Different Types of Transit Levels

Automatic – Also known as “self-leveling,” the purpose of an automatic transit level is to remain accurate and level regardless of ground vibration, environmental changes, or rough handling. While traditional instruments use graduated leveling vials that can produce slightly “off” results due to ground vibration or temperature, automatic levels use compensators that stabilize the line of sight. This makes automatic transit levels a great choice for structural framework like foundations and floors as well as large-scale surveying on difficult terrain.

Speed Line – A type of transit level beneficial for rough angle turning as well as fine tuning measurements. These levels may include clamps or tangents that stabilize the instrument and enable easy setup. Some models also include vertical arcs that work in conjunction with horizontal circles to help measure angles accurately.

Universal – The kind of transit level designed for use on any type of horizontal or vertical sighting (e.g. localized building projects as well as large surveying or agricultural jobs).

 

When to Use Transit Levels

You should use transit level to determine straight lines and accurate measurement at the start of any major construction or surveying job. A transit level measures the exact distance of surface or target height over the visible line of a project. While some people assume you can just use global positioning systems (GPS) for surveying or forestry projects, transit levels are necessary for measuring the grade or slope in any hands-on construction or engineering task.

 

How to Use Transit Levels

Ensure the base has a stable surface. Line up the transit level telescope over the leveling screws to find your base positioning. Next, rotate your telescope 90 degrees until the instrument reads center. Once you have established this baseline, move the instrument through 360 degrees (in 90-degree increments) to begin leveling. Since different brands have additional features, refer to the user manual for specific details.

 

Best Practices for Transit Levels

Operation – While operating a transit level is relatively straightforward and safe, most brands recommend wearing gloves and finding a stable ground surface before you begin using the product.
Safety – Keep your transit level in an identifiable case to prevent damage or breakage on construction sites.
Storage – Most transit levels come with hard carrying cases for storage between use. These cases are essential for protecting the instrument from damage in rough construction environments. Between projects, store the tool in a cool, dry place away from direct sunlight.
