Detecting Fish Schools Aurally

Sometimes you may be preoccupied with other tasks and unable to concentrate on watching the sonar picture. In such cases it would be a good choice to use the audio function. This function enables you to monitor echoes from fish schools and seabed through the built-in speaker.

After you’ve become accustomed to monitoring fish aurally, you should be able to detect a fish school from a range longer than you can detect it on the screen. In addition you may judge whether the fish school is approaching or going away; the tone becomes higher when the school is approaching and lowers when the school is going away.

1.Operate the trackball to place the trackball mark to the direc- tion you want to monitor through the speaker.

2.Press the R/B key. The bearing mark appears on the display. Echoes in a 30° , 60° , 90° , 180° or 330° sector centering the bearing mark are monitored through the speaker. You can adjust speaker volume with the AUDIO control.

3.To change coverage area, open the data setting window (sub panel 2) and change width of AUDIO SECTOR.

4.To scan the coverage area, open the data setting window, turn on AUTO SCAN and set scanning WIDTH.

Note: You can display the signal monitored through the loud- speaker on the history display combination window by pressing the HIST key, if AUDIO is selected on the HIST Window DSP menu in the USER menu.

The radar boasts a 12.1-inch color LCD screen that provides a crisp and clear view, allowing operators to easily identify targets and navigate in challenging conditions. The intuitive user interface facilitates quick access to essential radar functions, making it user-friendly even for those who may not be experts in radar operation.

A notable technological advancement in the CSH-73 is its digital signal processing (DSP) technology, which dramatically improves target detection capabilities, especially in adverse weather conditions. This technology helps to filter out noise and clutter, enabling the radar to provide accurate readings and reliable targeting information. The advanced target tracking capabilities allow users to monitor multiple vessels simultaneously, enhancing situational awareness.

In addition to its impressive detection capabilities, the CSH-73 features an Automatic Radar Plotting Aid (ARPA), which aids in collision avoidance by tracking the course and speed of approaching vessels. This sophisticated system simplifies decision-making for the crew, promoting safer navigation.

Another key innovation is the integration of Ethernet and NMEA 2000 connectivity. This feature enables seamless integration with other onboard systems, such as chart plotters and autopilots, creating a comprehensive navigation network. This connectivity allows for real-time data sharing, which enhances the overall operational effectiveness of the vessel.

The CSH-73 is also equipped with a range of customizable settings, allowing mariners to tailor the radar display to their specific needs and preferences. Features such as adjustable gain, sea clutter, and rain clutter suppression enhance the radar's performance under various environmental conditions.

Constructed with durability in mind, the CSH-73 adheres to robust marine standards, ensuring reliable performance even in the harshest maritime environments. This resilience is crucial for commercial vessels that regularly operate in challenging conditions.

In summary, the Furuno MODEL CSH-73 stands out as a powerful tool for enhancing maritime safety and navigation. Its advanced technologies, user-friendly interface, and durable construction make it an essential component for modern vessels, providing mariners with the confidence they need to operate effectively in any navigational scenario. The CSH-73 continues to uphold Furuno's reputation for excellence in marine electronics, making it a trusted choice for professionals worldwide.
