Which leveling instrument would provide the quickest measurement of ground elevation near a benchmark?

1. Hand level

2. Total station

3. Self-leveling level

4. Dumpy level

The correct answer is: Hand level

The quickest measurement of ground elevation near a benchmark would be achieved with a self-leveling level. This instrument automatically adjusts to a level position, allowing for immediate use without the need for manual leveling adjustments. It enhances efficiency by providing rapid and accurate readings of elevation compared to other instruments. A hand level requires the user to estimate the elevation by sighting, which can be time-consuming and less precise. A total station, while highly accurate and versatile, often involves more setup time and data processing, making it less efficient for quick elevation measurements compared to a self-leveling level. The dumpy level also requires thorough manual leveling and focusing before taking a measurement, adding extra steps that can delay the process. In practice, for swift elevation measurements, particularly near established benchmarks, a self-leveling level is the optimal choice.
