Which feature is characteristic of a dumpy level?

1. It has an internal compensator

2. It uses a rotating laser for measurement

3. It possesses fixed crosshairs

4. It automatically levels itself

The correct answer is: It possesses fixed crosshairs

The characteristic feature of a dumpy level is that it possesses fixed crosshairs. This tool is designed primarily for horizontal leveling and establishing straight lines of sight for surveying purposes. Unlike more advanced instruments, a dumpy level does not include any internal compensator or self-leveling capabilities. The fixed crosshairs allow surveyors to aim accurately at a survey stake or reference point, ensuring that the line of sight remains constant and precise during measurements. While some other leveling instruments may feature automatic leveling or rotating lasers to facilitate measurements, a dumpy level relies on manual adjustments and the stability of its fixed crosshairs to achieve its purpose. This simplicity makes the dumpy level a reliable choice for many traditional surveying tasks.
