Key features
The Simrad CS90 is a perfect "catching machine", ideal for mackerel, tuna and fish close to bottom detection. The combination of horizontal and vertical beams shows you the fish as "birds eye" and "slice" simultaneously. This provides vital school data without having to pass over the target. Full beam stabilization maintains a clear picture of the targets even in rough seas.

The narrow beams provided by the CS90 give you several advantages. They increase the range and resolution, and offer a vertical view with additional details and a clearer picture. The narrow beams also decrease the noise level.
