The echosounder | NSS Operator Manual
Placing a mark on an echosounder image
You can position a mark at the vessel’s position by pressing and holding the MENU key.
You can position a mark on a selected echosounder item by tapping the screen and then
activating the menu.
 Note: Only marks positioned by using the cursor will include depth information.
Measuring distance
The cursor can be used to measure the distance between the position of two observations on
the sounder image. It is easier to use the measure function when the sounder image is
paused.
1. Activate the menu to start the measure function
- The cursor will be positioned in the middle of
the panel, and the distance will be measured
from this position
2. Tap on the screen to select the second measuring
point
- A line will be drawn between the measuring
points, and the distance will be listed in the
Information window
3. Continue tapping the screen to position new measuring points
When you press the Finish measuring panel button or the
X key the echosounder will
resume to normal scrolling.
Pausing the echosounder
You can pause the sounder, allowing you to examine the sounder echoes. The function is
activated from “The echosounder settings panel”, see page 55.
This function is useful when you need to position a waypoint exactly on the echosounder
panel, and if you are using the cursor to measure a distance between 2 elements on the
image.
Recording the echosounder data
You can record echosounder data and save the fi le internally in the NSS unit, or on to a Micro-
SD card inserted into the unit’s card reader.
The function is activated from “The echosounder settings panel”, see page 55.
The following options are available:
Bytes per sounding
Select how many bytes per seconds that are to be
used when saving the log fi le. More bytes yield better
resolution, but will cause the record fi le to increase in
size compared to using lower byte settings.
Log all channels
Logs all available sonar data simultaneously.
When logging all channels, logs are saved in SL2
format instead of .slg format.
Log in XTF format
Optional logging format for SideScan data. This will only be available when a StructureScan
unit is connected.
This format does not log all channels into one fi le. The format is used for third part application
support on the PC (like SonarWiz) that need access to the StructureScan data.
