and sometimes fingers get crossed. Sorry guys. The abd was supposed to be and. Missed with my typing finger and hit the b in place of the n.
rdstair, can you post a Screen Snapshot of what the Si and Di sonar looks like. Try getting an image of the combo Si - Di sonar View. I had someone on this or another web site that was having almost the same problem but it was due to the Si sonar not working, which I noted after seeing a Screen Snapshot of what they were seeing.
The Di sonar comes from the Si sonar; so what helps the Si sonar looks better (like a slower moving boat) should make the Di sonar look better.
