Which mode is best for pinpointing the target line during a 360 sweep or survey?

The best mode for pinpointing the target line during a 360 sweep or survey is peak mode. This mode is designed to detect and reflect the highest signal strength received from a utility line, making it particularly effective for locating the precise location of underground utilities within the survey area.

Peak mode enhances the operator's ability to discern the strongest signal from potential utilities, allowing them to determine the exact alignment of the target line more accurately. This mode is especially valuable when navigating areas with multiple overlapping signals, as it helps to filter out noise and minimize the chances of false readings.

Using other modes, such as null mode or sweeping mode, may not provide the same level of precision for pinpointing specific utility lines. Null mode focuses on minimizing interference rather than highlighting the strongest signal, and sweeping mode is more about scanning vast areas rather than honing in on specific locations. Therefore, peak mode stands out as the optimum choice for accurately identifying and following a target line during a 360 survey.
