Advanced StructureScan settings
TVG
Wave action and boat wakes can cause onscreen clutter near the surface. The TVG (Time
Variable Gain) option reduces surface clutter by decreasing the sensitivity of the receiver near
the surface.
Ú
Note: For optimal image return and clarity in most conditions, the default value is set to
3, the maximum (range is 0-3).
Flipping the Structure image left/right
If required, the left/right SideScanning images can be flipped to match the direction of the
transducer installation.
Range Lines
Range lines can be added to the image to make it easier to estimate depth (Downscan) and
distance (SideScan).
Recording StructureScan data
You can record StructureScan data and save the file internally in the NSS evo3 unit, or onto
memory card as described in "Start Recording echosounder data" on page 78.
