2. FINE TUNING THE SONAR PICTURE

2.6Choosing Beamwidth

2.6.1Horizontal beamwidth

If you wish to have better bearing discrimination (ability to distinguish two closely located targets at the same range and different bearings) for fish schools and also wish to examine the contour of bottom, set HOR BEAMWIDTH to NARROW, on the SONAR menu.

2.6.2Vertical beamwidth

For better bearing discrimination in the vertical direction, set VER BEAMWIDTH to NARROW, on the SONAR menu.

2.7Deleting Weak Echoes

You can remove weak echoes to clear the picture. Echoes are deleted by strength so this feature is useful for observing only large fish schools or suppressing interference.

1.Press the [MENU] key to open the menu.

2.Use the [RANGE] control to choose [MENU MODE] at the top of the screen.

3.Use the [GAIN] control to choose SONAR.

4.Use the [RANGE] control to choose DELETE COLOR.

5.Use the [GAIN] control to choose setting. The setting range is 0-10 and the higher the number the stronger the echo that will be erased.

6.Press the [MENU] key to close the menu.

2.8Echo Averaging

You may adjust echo afterglow to follow echo movement. The higher the setting the longer the afterglow remains on the screen.

1.Press the [MENU] key to open the menu.

2.Use the [RANGE] control to choose [MENU MODE] at the top of the screen.

3.Use the [GAIN] control to choose SONAR.

4.Use the [RANGE] control to choose ECHO AVERAGE.

5.Use the [GAIN] control to choose setting. The setting range is 0 (OFF) to 3 and the higher the setting the longer echoes remain on the screen.

6.Press the [MENU] key to close the menu.

CSH-5L/CSH-8L specifications

Furuno CSH-5L and CSH-8L are advanced marine radar systems known for their cutting-edge technology and user-friendly interfaces. Designed primarily for maritime applications, these radar units cater to a wide range of vessels, from commercial ships to fishing boats. The primary distinguishing feature of the CSH-5L and CSH-8L radar systems lies in their ability to provide high-resolution images and precise detection of targets, ensuring navigational safety and operational efficiency on the water.

One of the standout technologies incorporated into both models is the pulse compression technique. This feature significantly enhances target resolution and minimizes blind spots, allowing the radar to detect smaller objects at greater distances. With the CSH-5L and CSH-8L's powerful signal processing capabilities, users can expect exceptional performance even in challenging weather conditions, ensuring reliable operation during storms or fog.

The CSH-5L model operates at a frequency range of 5 GHz, while the CSH-8L uses an 8 GHz frequency. Both radars are equipped with a rotating antenna that provides a wide coverage range, allowing for efficient monitoring of the surrounding marine environment. Their high sensitivity and low noise levels enhance target detection, making them particularly useful for locating small fishing vessels or buoys.

Another important characteristic of the Furuno CSH-5L and CSH-8L is their user-friendly interfaces. Both models feature intuitive controls, allowing operators to adjust settings easily and access critical information quickly. The displays are designed for clarity, enabling users to distinguish between targets and navigate effectively.

Additionally, the radar systems include advanced features such as automatic target tracking and target acquisition capabilities. This functionality allows users to monitor multiple targets simultaneously, providing essential situational awareness for safe navigation. The CSH-5L and CSH-8L also support integration with other onboard systems, including ECDIS (Electronic Chart Display and Information System), which enhances the overall effectiveness of maritime navigation.

In summary, the Furuno CSH-5L and CSH-8L radar systems represent the forefront of marine radar technology, offering exceptional detection capabilities, user-friendly controls, and robust integration options. Their advanced features ensure that mariners can navigate confidently, making them a vital asset for anyone operating in the marine environment.
