practice using the tool and get comfortable with the display and data representation in good weather and
in good conditions so that when you find yourself in situations where you really need the sonar, you will be
comfortable and well versed in its operation.
The following discussion will use an example ping of a bridge piling in deep water in an effort to illustrate
the aforementioned controls. For this discussion, a single ping of a deep water bridge piling (Figure 24,
“Bridge piling used in control setting images”) is processed with various control settings. This environment
was used because of the simple sea floor and simple in-water target environment.
NOTE: Once the sonar's settings are set appropriately, it will generally not be necessary to frequently change
the settings unless the water environment changes drastically.
NOTE: In very soft, silty bottom environments, the bottom may not be detected well or at extended water
depths. Even in this case though, in-water targets will be well detected. Large rocks, pilings or other "hard"
targets sitting in the silt will also be detected well. These targets may be shown as in-water targets rather
than the sea floor.
