Multiple Choice

In which mode should active locating of facilities ALWAYS be performed?

Explanation:
Active locating uses a tracer signal, and the most reliable cue is the strongest signal directly above the buried line. In Peak mode, the locator returns the highest amplitude where the line is located, giving a clear, accurate trace of the facility path and more dependable depth indication. Null mode, which relies on finding a minimum signal, is more prone to interference from nearby utilities and noise and can lead to ambiguous readings. Manual mode is just a control setting for adjusting sensitivity and does not itself indicate the line location. For consistent and trustworthy locating, Peak mode should always be used.
