HOW TO READ THE DIAL
Objects Under Water A lake bottom is seldom level or uniform, and objects in the water or on the bottom may also vary in depth. The dial readings will indicate these varying conditions accordingly. To distinguish between the dial indications of rocks and fish, anchor the boat and watch for signals that change. A changing signal will usually indicate a moving fish.
Pages 23 through 25 show you examples of underwater conditions and dial readings. Study these drawings for help in interpreting what you read on the dial.
NOTE: For additional information and illustrations showing the interpretation of the depth sounder readings, refer to the "Humminbird Trouble Shooting and Consumer Information Guide."
