receiver speaker volume decreases. As the antenna moves off the target path,
the bar graph opens, the signal strength increases, and the speaker volume
increases. Gain adjust is automatic in DirNull mode.
The center of the DirNull screen provides a ‘compass view’ of the target
path. An arrow will point toward the location of the cable/pipe in 45-degree
steps. A solid line will appear over the cable/pipe, indicating its orientation
to the receiver handle.
For example:
Figure 1: If the target path is to the right of the receiver, and running
parallel to the operator, the right arrow will display.
Figure 2: If the target path is to the left and in front of the operator (not
running parallel to the receiver) the arrow will point toward the top left side
of the screen.
Figure 3: When the receiver crosses the target path, a solid line will appear,
instead of arrows, indicating the target path and its orientation to the receiver.

Before marking target path, always use directional peak mode to verify
location.
Special Peak (Spl Pk)
Special Peak Mode turns on only the peak antenna closest to the ground.
Special Peak Mode is used in applications such as very deep cable, or when
the signal is too weak for normal or directional peak tracing.
