What unique capability does a transit level have compared to a builder's level?

A transit level possesses a unique capability that distinguishes it from a builder's level, particularly in its ability to tilt upward to measure angles from the vertical. This feature allows for a greater range of applications, including both horizontal and vertical measurements.

In construction and surveying, being able to measure angles in both the horizontal plane and the vertical plane is crucial for tasks that require precise alignment and elevation determination. The tilt feature enables the transit level to create a plumb line or establish vertical alignment with high accuracy, which is essential for tasks like setting the heights for various structural elements.

In contrast, a builder's level is primarily designed for leveling horizontal surfaces and does not have the same versatility for measuring angles from vertical positions. This limitation makes the transit level a more comprehensive tool for surveying and construction projects that require both horizontal and vertical precision.
