StructureScan image. It is easier to use the measure function when the sounder image is
paused.

Pausing StructureScan™
You can pause the StructureScan, allowing you to examine the structures and other
images in more depth and detail.
This function is useful when you need to position a waypoint exactly on the Structurescan
image, and if you are using the cursor to measure a distance between 2 elements on the
image.
Recording StructureScan™ data
You can record StructureScan data and save the file internally in the NSO-II unit, or onto an
SD card as described in "Recording and viewing the echosounder data" on page 61.
Structure options
Structure palette
Several display palettes with varying degrees of color and brightness are available.
Structure noise rejection
Signal interference from bilge pumps, engine vibration and air bubbles can clutter the
StructureScan image.
The noise rejection option filters the signal interference and reduces the on-screen clutter.
TVG
Wave action, boat wakes and temperature inversion can cause on-screen clutter near the
surface.
The TVG option reduces surface clutter by decreasing the sensitivity of the receiver near
the surface.
Flipping Left/Right image
If required, the left/right SideScanning images can be flipped to match the corresponding
side of you vessel.
Structure source
If you have more than one StructureScan on your network, you can select which unit to be
the preferred source on this NSO-II unit.
