A line tracer is a specialized tool used primarily for locating underground service lines, such as electrical cables, water pipes, or gas lines. This instrument is particularly important in landscaping and construction projects to avoid damage to these buried utilities during excavation or installation processes. By sending a signal through the buried lines, the line tracer can help identify their exact location on the surface, ensuring that these service lines are not accidentally disturbed, which could lead to serious hazards or costly repairs.

The other options focus on different tools or methods that serve different purposes. For instance, measuring soil pH typically involves using pH meters or soil test kits specifically designed for assessing soil acidity or alkalinity. Identifying plant species usually requires a combination of botanical knowledge and resources such as plant identification guides or apps. Checking for irrigation leaks involves inspecting the system itself, typically with visual methods or specialized equipment focusing on water flow, rather than using a line tracer. Each of these functions is distinct, which underscores the specific role of a line tracer in ensuring safe and effective landscaping practices.
