Marport CATCH User Manual page 25

The echogram can automatically switch to a 20-meter range when the distance to the
bottom is less than 20 meters (1).
The change of range depends on the settings configured on Mosa2.
The following Sounding Mode options must be set in Mosa2:
• Automatic Range must be activated.
• The Mode must be set to Down only.
• The Refresh Rate must be set to Fast.
• The Trawl Opening must be lower than 18.5 meters to be able to switch to a 20-
meter range.
Note: The trawl opening value sets the minimum distance to see inside the
trawl. As a result, if the trawl opening distance is equal or higher than 18.5, the
sensor will not reduce the range to 20 meters.
See Configuring the Echo Sounder (on page 22) for details about Mosa2 settings.
