What is a "line tracer" used for?

1. Creating underground irrigation systems

2. Locating underground service lines

3. Measuring distances for landscaping

4. Marking boundaries of properties

The correct answer is: Locating underground service lines

A "line tracer" is primarily used for locating underground service lines. This specialized tool works by sending signals through the ground to identify the path of underground utilities such as water, gas, or electrical lines. Understanding the exact location of these lines is crucial for any landscaping project, as disturbing them can lead to service interruptions, safety hazards, and costly repairs. This function is particularly important during excavation or similar activities where there’s a risk of damaging the utilities. By accurately tracing these lines, landscapers can ensure that their work complies with safety regulations and does not interfere with existing services. This not only protects the integrity of the utilities but also helps in avoiding any inadvertent liabilities that could arise from digging into unknown services. In contrast, the other options concern different aspects of landscaping and construction. Creating underground irrigation systems involves designing and installing irrigation components, measuring distances for landscaping pertains to planning and layout tasks, and marking boundaries of properties is concerned with land surveying. While all of these functions are vital in the landscaping process, they do not specifically relate to the function of a line tracer.
