Why is it better to use a leveling rod than a yard stick when using a transit?

The preference for using a leveling rod over a yardstick when working with a transit is primarily due to the fact that leveling rods are typically designed to be longer, which facilitates more accurate measurements over extended distances. The added length of a leveling rod allows for better visibility and reference points when aligning the rod with the transit's line of sight, especially on larger construction sites or in open areas where distances can be significant.

The design and functionality of leveling rods also consider practicality in construction settings. They often feature clear and bold markings that are specifically useful for precise leveling tasks, which can further contribute to their effectiveness as a tool in conjunction with a transit. This long reach and ease of visibility play crucial roles in ensuring construction accuracy and efficiency.

In contrast, a yardstick, which is usually shorter, may limit the user's ability to measure and read grades from a distance, making it less suitable for transit operations that require a high degree of precision.
