Range
The range setting determines the water depth that is visible on the
screen.
Ú
Note:
Setting a deep range in shallow water may cause the
system to lose track of the depth.
Preset range levels
Select a preset range level manually from the menu.
Auto range
In auto range, the system automatically displays the whole range
from the water surface to the bottom.
Auto is the preferred setting for fish finding.
Select the range option and then the auto option in the menu.
Frequency
The unit supports several transducer frequencies. Available
frequencies depend on the transducer model that is configured for
use.
• A low frequency, for example 50 kHz, will go deep. It generates a
wide cone but is more sensitive to noise. It is good for bottom
discrimination and wide area search.
• A high frequency, for example 200 kHz, offers higher
discrimination and is less sensitive to noise. It is good for
separating targets and for higher speed vessels.
Gain
The gain controls the sensitivity. The more you increase the gain,
the more details are shown on the image. However, a higher gain
setting may introduce more background clutter. If the gain is set too
low, weak echoes might not be displayed.
A manual and an automatic gain mode are available. By default, the
gain is set to Auto.
