Echosounder settings
A compatible echosounder module (or another unit which has built-in sonar) shared over
the Ethernet network is required to view echosounder images on the unit.
Network echosounder mode
The network echosounder mode setting selects whether only one or multiple echosounder
sources can be selected at the same time.
Ú
Note: Changing the mode requires that all connected sources are restarted.
Overlay DownScan
When a DownScan capable transducer is connected to your system, you can overlay
DownScan images on the regular Echosounder image.
When overlay DownScan is activated, the Echosounder panel menu expands to include basic
DownScan options.
View sonar log
Used to view recordings. The log file is displayed as a paused image, and you control the
scrolling and display from the menu.
You can use the cursor on the image, measure distance, and set view options as on a live
image. If more than one channel was recorded in the selected log file, you can select which
channel to display.
Structure depth offset
All transducers measure water depth from the transducer to the bottom. As a result, water
depth readings do not account for the distance from the transducer to the lowest point of
the boat in the water or from the transducer to the water surface.
• To show the depth from the lowest point of the vessel to the bottom, set the offset equal
to the vertical distance between the transducer and the lowest part of the vessel, A
(negative value).
• To show the depth from the water surface to the bottom, set the offset equal to the
vertical distance between the transducer and the water surface, B (positive value)
• For depth below transducer, set the offset to 0.
