A new generation of digital sonars: Koden KDS-6000BB Broadband Sonar

Advanced Broadband Technology

KDS-6000BB is the world’s first Broadband searchlight sonar. The most suitable output frequency in a range from 130 to 210 kHz can be selected in the 0.1 kHz step depending on the target and its range. Selection of frequency is easy and quick. Flexible selection of frequency enables the user to stay away from interference with the sounders on the other vessels.

Digital signal processing enables high-resolution images

Newly-developed KDP-V (Koden Digital Processing series V) digital signal processing system provides high-resolution images in closer range and noise reduction performance in the longer range.

High scan speed for fast fish detection

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

Four different presentation modes are available for different fishing practices:

  • Sonar mode is useful for searching around the ship.
  • Off-center mode helps to show more information ahead of the ship.
  • Echo sounder mode to display images like a fishfinder.
  • Bottom scan mode can display reflected echoes from underwater objects and seabed.

User-friendly interface with Condition Memory buttons

Six CM (Condition Memory) buttons allow the user to preset all the current settings and recall them instantly with just one push of a button. It is like having six different sonars in one unit.

Black Box type

KDS-6000BB comes in a black box. The user can select a monitor from the market or order our optional 17-inch LCD monitor which will be supplied along with KDS-6000BB sonar.

Space-saving hull unit

A newly-designed compact hull unit allows for saving space on your vessel.
