Tough to say. You are going 4.7 mph. Try going a little slower. The faster you go the smaller the image. I think closer to 3 mph is recommended if I am not mistaken.

I am looking at the individual shadows under each area. The top one is harder to see cause they are closer to bottom.

But I still see individual fish in the top pic and shadows. To me the Crappie look much bigger than what you have there
