Click on the image to enlarge it. The sidefinder was looking out to the right side 70 feet. I have circled some of the fish and underwater features for a little more in depth explanation of the sidefinder view. The screen is scrolling from the top to the bottom so what you see at the top is what was just passed over. The shadow was where the tree blocked off the sound that the sidefinder uses to “see” what is under the water much the same as a tree trunk would block off the light and make a shadow above the water.  The sidefinder allows you to “see” what is in a spot without actually driving over it and scaring the fish. The depth of 1.1 feet is inaccurate due to the sensitivity being turned up so as not to miss anything . The depth is really 3.5 feet . If the depth is over 5 feet it reads correctly at that sensitivity setting.
