High sensitivity over long range!


Digital signal processing achieves high sensitivity at long distances at any frequency

KDS-5500BB is a fixed frequency digital sonar.
Higher frequencies increase the resolution and provide detailed image expression. Lower frequencies increase sensitivity at long distances and enable detection at deeper depths. (Select frequency at time of purchase).

Digital signal processing enables high resolution images

Both of high resolution in closer range and noise reduction performance in longer are materialized at high level with newly-developed digital signal processing, KDP-V (Koden Digital Processing series V).

High scan speed for fast fish detection

Scanning speed is remarkably increased by adding 15°and 20° in scanning sector angle steps. lt can detect surrounding fish schools quickly.

Four different presentation modes available for various fishing scenes

・Sonar mode is useful for searching around the ship.

・Off-center mode helps to show more information of ahead.

・Echo sounder mode for displaying image like fishfinder is also available.

・Bottom scan mode can display reflected echoes from underwater and seabed in a cross selection image.

User friendly operation with Conditional Memory keys

Six of CM(Condition Memory) keys offer the user to preset all the current settings and recall them instantly. It is like six sonars in one unit.

Black Box type

KDS-5500BB comes in black box. The user can select a monitor from the market or the optional 17/19 inch LCD monitor.

Space-saving Hull unit

Short stroke Hull unit available for small space.

Motion sensor

The stabilizer function reduces the disturbance of sonar display caused by the pitch and roll of the vessel. (For AS model)
