CH500

Incredibly fast training speed

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

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

The CH500 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 CH500 is able to detect fish that didn't appear with the non-stabilized echo.

Reverberation reduction function

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.

The CH500 also features fish and obstacle audio signals depending on the nature and the size of the detected object. Whether there are air bubbles, big or small fish schools, and seabed, the emitted sound is different. This feature shows its usefulness when used with the Full-circle A-scope mode, our recommanded combination to know the nature of the target with precision, and during long sea trips, as it frees the user from continuously watching the screen.

*Optional Loudspeaker part number 00146620000 is required

Higher resolution due to advanced signal processing

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.
