18. UNDERSTANDING SONAR DEL INO UF AND OING Understanding the Sonar Display One of the first things to understand about sonar is that the transducer sends a beam down to the bottom of the water much like the beam of a flashlight The beam starts small near your vessel and expands as it gets to the bottom See Transducer Coverage for more detailed information The Sonar Page does not show a three dimensional representation of the underwater environment the display is in two dimensions much like if you took a picture of an aquarium Only the depth of the item in the water appears The Sonar display does not show you where an item is located horizontally in the water as shown in the drawings below The fish is not directly above the tree in reality but it might look like it 1s on the Sonar Page Fish Tree Aerial View of the Water Sonar Display SETTING UP AND USING SONAR gt UNDERSTANDING SONAR Transducer Coverage The area covered by the transmitted sound waves is determined by the cone angle of the transducer and the water depth The wide cone angles 40 associated with low frequencies 50 kHz provide a large coverage area for finding fish within a coverage width that is approximately 2 3 of the water depth However this also means that wide cone angles produce less bottom detail and resolution As shown in the drawing on the near right the 40 cone angle produces a coverage area of approximately a 20 foot di
