A FarSounder customer vessel returns to a marina berth by the San Diego convention center.

The video begins with a sweep of the marina. Then we see video from the vessel's bridge.

The FarSounder sonar is set initially to color mapped to signal strength. A series of loud reflecting, in-water targets can be seen on the starboard side of the display. These are reflections from the pier pall that is seen out the window. The radar also sees this shore line.
