I enjoy learning...

The size and shape of the image he posted plus another post where he mentions his 998c Si unit…
I knew it was an 800 or 900 series unit by the shape of the screen snapshot and also from the location of the digital depth (this ruled out an 1100 series unit). The appearance of the Di sonar helped as well. I always fond the Si/Di to be more 3D looking in that I perceive depth to the Di sonar image versus the flat looking images from the dedicated single beam DI sonar units.
