Which tool is typically used for checking rough grade over a distance of up to 50 feet?

The hand level is a simple and effective tool designed for checking rough grades over relatively short distances, typically up to about 50 feet. It consists of a small level vial mounted on a straightedge or a similar frame, allowing the user to determine if a surface is level by looking through the level vial. This tool is particularly useful for basic grading tasks, where the precision of more advanced equipment is not necessary.

In contrast, the dumpy level and laser level are better suited for more precise leveling over longer distances and require setups that may not be practical for quick rough checks in tight spaces. A dumpy level, for example, is a more complex instrument that involves leveling using a tripod and is designed for surveying tasks where accuracy is critical over larger areas. The laser level provides a continuous beam of light to determine level and is excellent for long distances but may be overkill for a quick rough grade check. The clinometer is primarily used to measure angles of elevation or depression and is not designed for leveling surfaces, making it unsuitable for checking rough grades.

Using a hand level makes it an efficient choice for straightforward tasks where the goal is to quickly determine a general level rather than achieve precise measurements.
