On this SX90 screen capture, you can see that the sonar has detected three schools of herring. The skipper has decided to catch the school with highest density, and this is the school closest to the vessel. The sonar is in Automatic Target Tracking mode, and shows the tracks from the school and vessel. In the lower left corner you can see the course, depth and speed of the school; 179 degrees, 350 meters depth and 2,2 knots.
