Features

Two frequencies combined to increase your chances of finding fish

The low frequency will serve to cover a wide area horizontally around the ship, while the high frequency can be used in a vertical profile mode to help identify fish school, including their size and their movement. This information can help in properly deploying a net or steering a better course to reach the targeted school.

*Dual-frequency 60/153 kHz or 85/215 kHz to be selected

The dual-frequency can reveal the presence of sardines and whitebait

The use of both low and high frequencies shows the echoes that matter most to the fisherman. By comparing the two frequencies, or simply overlaying them, it becomes easy to locate and identify whitebaits.

Incredibly fast training speed means less tracking failures.

■ Faster motor delivering quicker training speed 【NEW】
Quick train speeds allow the sonar display to be refreshed at a faster rate aiding in earlier detection of fish and obstructions.

■ 6 step angles for speed adjustement according to user's needs 【NEW】

The CH-600 is one of the most comprehensive and fastest sonars of its kind. It provides 6 selectable step variations (6°, 12°, 15°, 18°, 21° or 24°) for high scanning speed that can cover sector widths from 24° to 360° in a couple of seconds. Thanks to its high training speeds, the CH-600 can rapidly scan a large area providing the ultimate fishing and navigational experience.

Expert tip:  When moving fast, you can use a wider step angle in order to get a glimpse of the surrounding area. If you detect sonething interesting, slow down and switch to a decreased step angle for clearer echoes.

Smart features to efficiently catch fish

■ Built-in motion sensors provide a stabilized target presentation in rough sea conditions   

【Standard equipment】 ​ 


The CH-600 searchlight sonar is the first of its class to have integrated motion sensors.
In rough seas, vessels tend to move in every direction. This movement can cause inaccurate target information to be displayed. The role of the integrated motion sensors is to precisely compensate for those negative effects and provide accurate data to the user.

In the right hand picture above, you can see that once the stabilizer is activated, the bottom echo recovers its circular shape. The sonar is then able to provide accurate data in different sea conditions. Thanks to its integrated motion sensors, the CH-600 is able to detect fish that didn’t appear with the non-stabilized echo.


■ Reverberation reduction function 【NEW】

The reverberation reduction offers both better understanding and better appreciation of
the nature of detected echoes. Below is an example of how the Reverberation reduction function highlights the wreck from the surrounding seabed.

*The echo may be subject to interferences from other Fish Finders 
*Schools with excessivly high density may appear with a weaker echo color

■  Full-circle A-Scope mode and audible target detection 

The A-Scope mode shows the last detected echoes with one single color. The nature of the target can be quickly understood as the size of the echo is greatly amplified and even the smallest echoes are shown.
*The more opaque the color, the latest the echo.

Image clarity and high resolution echoes

■ Advanced signal processing offering high resolution【NEW】

A powerful signal and image processing based on a unique interpolation technology provides images in high resolution. Even if the fish are located near the seabed, the different echoes are clearly shown and easy to understand. Additionally, the high resolution echo display gives crisp, clear echoes, which reduces stress on the eyes.
