Noise rejection
Echosounder signal interference from bilge pumps, engine vibration and air bubbles can
clutter the sounder image.
The noise rejection option filters the impact of echosounder signal interference by
reducing the on-screen clutter.
Clarity
Wave action, boat wakes and temperature inversion can cause on-screen clutter near the
surface.
The surface clarity option reduces surface clutter by decreasing the sensitivity of the
receiver near the surface.
Recording the echosounder data
You can record echosounder data and save the file internally in the NSE unit.
You can select how many bytes per seconds that is to be used when saving the log file.
More bytes yields better resolution, but will cause the record file to increase in size
compared to using lower byte settings.
