5. cone shape similar to a flashlight beam covering a smaller circular area at the top and angling out to a larger circular area at the bottom Fishfinder 160C Owner s Manual GETTING STARTED gt UNDERSTANDING THE FISHFINDER AND SONAR These sound waves reflect off of any object that they hit and then the waves travel back up to the transducer These objects could be fish branches the bottom or any other object that has density that is different from the water The transducer receives the sound wave information and then sends the information to the Fishfinder The Fishfinder shows the information on the screen for you to see and interpret The type of transducer and settings that you choose determine how the information appears on the screen Understanding the Fishfinder Screen Experimentation and experience are the keys to successfully interpreting your Fishfinder screen We recommend that you take your Fishfinder out on familiar water and spend time learning to interpret what you see on the Fishfinder 160C screen Think of the Fishfinder screen as if you took a picture from the side of an aquarium in your home You can see how deep a fish is in the water how close it is to the top or bottom but you cannot tell where the fish is located horizontally in the water whether it is near the front or the back of the aquartum Remember this when you are trying to locate exactly where something is in the water The strongest sonar re
