Operating With the Distortion Line If the Tracing Line s distortion response blurring is disabled the detected field will be shown with two lines one solid the Tracing Line and one dashed the Distortion Line The dashed Distortion Line can be separately selected to be on or off in the Display Elements menu The dashed Distortion Line is the signal as seen by the upper antenna node and the solid Tracing Line is the signal as seen by the lower node Figure 65 Screen Display with Distortion Line Line Trace Mode The Tracing Line without the dynamic distortion response blurring still represents the location and the direction of the signal being traced It still reflects changes in direction of the target utility And it helps recognize signal distortion when compared to the dashed Distortion Line if something is interfering with the signal and distorting its shape the Distortion Line could be significantly offset or skewed The Tracing Line represents the signal received by the lower antenna node The Distortion Line represents the signal received by the upper antenna node If these two do not align or they do not reflect the same information as the Guidance Arrows about where the center of the field is then the operator knows he is looking at some kind of distortion The two lines may also move randomly if a weak signal is being received indicating that the locator circuit needs to be improve
