Features

Incredibly fast training speed

■ Faster motor delivering quicker training speeds 【NEW】
Faster training speed can aid in earlier detection regarding fish targets or obstruction avoidance.

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

This CH-500 sonar is one of the most comprehensive and fastest sonars of its kind. It provides 6 selectable step variations (6°,12°,15°,18°,21° and 24°) for high scanning speed that can cover sectors widths from 24° to 360° in a couple of seconds. Thanks to its high training speeds, the CH-500 can rapidly scan a large area providing the ultimate fishing and navigational experience.

Expert tip: While moving fast, use the 24° step scan in order to get a glimpse of the surroundings. If you detect something interesting, slow down and switch to a decreased step angle for clearer echoes.

Smart features to efficiently find local fish

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

【Standard equipment】 ​ 


The CH-500 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-500 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

■ Higher resolution due to advanced signal processing【NEW】

A powerful signal and image processing techniques, 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. The higher resolution display yields a presentation that is crisp and clear.
