Viewing recorded data
Both internally and externally stored sounder records can be reviewed when the view sonar
log option is selected in the echo settings dialog. Refer to "Echosounder settings" on page 78.
Upload sonar logs to C-MAP Genesis
To upload sonar logs to C-MAP Genesis do one of the following:
• Use the services option. Follow the prompts to sign in and transfer the log files to C-MAP
Genesis.
• Use the Storage dialog. Select the sonar logs icon and the logs you want to transfer. If you
are already signed in to C-MAP Genesis the files are transferred. If you are not signed in,
select the transfers icon and follow the prompts to sign in and transfer the log files to C-
MAP Genesis. You can sign in and transfer files at a later time when the unit is connected
to the internet.
Customizing the image
Use the menu to customize the image. When the cursor is active, some options in the menu
are replaced with cursor mode features. Select the clear cursor option to return to the normal
menu.
Range
The range setting determines which 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.
