Weak bottom echo, digital readings erratic, or no fish signals:

1.Make sure the transducer is pointing straight down. Clean the face of the transducer. Oil, dirt and fuel can cause a film to form on the trans- ducer, reducing its effectiveness. If the transducer is mounted inside the hull, be sure it is shooting through only one layer of fiberglass and that it is securely bonded to the hull. When attaching a transducer to the inside of a hull, ONLY use the epoxy available from LEI (order in- formation is inside the back cover). Do NOT use RTV silicone rubber adhesive or any other type of epoxy. The LEI epoxy is specially formu- lated so that it will cure properly for shoot-through applications.

2.Electrical noise from the boat's motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker signals such as fish or even structure from the display.

3.The water may be deeper than the sonar's ability to find the bottom. If the sonar can't find the bottom signal while it's in the automatic mode, the digital sonar display will flash continuously. It may change the range to limits far greater than the water you are in. If this hap- pens, place the unit in the manual mode, then change the range to a realistic one, (for example, 0-100 feet) and increase the sensitivity. As you move into shallower water, a bottom signal should appear.

4.Check the battery voltage. If the voltage drops, the unit's transmitter power also drops, reducing its ability to find the bottom or targets.

Bottom echo disappears at high speeds or erratic digital read- ing or weak bottom echo while boat is moving

1.The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets. The technical term for this is cavitation.

2.Electrical noise from the boat's motor can interfere with the sonar. This causes the sonar to automatically increase its Discrimination or noise rejection feature. This can cause the unit to eliminate weaker

320C specifications

Eagle Electronics has made significant strides in the world of marine electronics with the introduction of the Eagle Electronics 320C. This compact, feature-packed device is designed to cater to both novice and experienced anglers, providing them with the necessary tools to enhance their fishing experience.

One of the standout features of the Eagle 320C is its high-resolution color display. With a screen size of 3.5 inches, the unit exhibits a bright and vibrant backlit display, ensuring exceptional visibility even in bright sunlight. The 320C employs a user-friendly interface, allowing quick navigation through its various functions and settings.

The 320C is equipped with advanced sonar technology, featuring dual-frequency capabilities. This enables users to switch between 83 kHz for wider coverage and 200 kHz for more precise detail. This flexibility in frequency options allows anglers to target specific fish species and efficiently optimize their fishing strategies. The device also boasts a powerful 300-watt RMS power output, ensuring clear and accurate sonar readings down to depths of 600 feet.

Another important characteristic of the Eagle 320C is its ability to display detailed bathymetric maps. With built-in mapping capabilities, users can access contour mapping, which provides essential information about the underwater landscape. This feature is especially valuable for locating structures such as submerged rocks or vegetation, which are often prime habitats for fish.

In addition to sonar and mapping functions, the Eagle 320C also includes a variety of customizable settings. Users can personalize various aspects of the display, including color palettes, sensitivity, and sonar depth range to suit their preferences. This level of customization helps maximize the device’s effectiveness in diverse fishing conditions.

Moreover, the Eagle Electronics 320C is designed with durability in mind. It features a rugged, waterproof casing that is built to withstand harsh marine environments. This resilience ensures that the device can reliably face saltwater exposure, rain, and other challenging conditions commonly encountered while fishing.

Overall, the Eagle Electronics 320C is an exceptional tool for anglers seeking a comprehensive fishing solution. With its high-resolution color display, advanced sonar capabilities, detailed mapping functionalities, and customizable settings, the 320C provides a robust platform for enhancing fishing success, making it a valuable addition to any boat.
