Practical Hybrid Interface

The best of both approaches


The SWx series maximizes the combined benefits of a touch screen with the reliability of an ergonomic keypad

  • The rotary knob provides fast and precise control in every condition

  • The touch screen optimizes experience in map exploration and route building


SEIWA CHIRP technology

Higher resolution, less power, less noise

SEIWA SWx combo displays come with a CHIRP sonar to  offer  a high resolution view of targets for an efficient and sustainable fishing.

CHIRP stands for Compressed High-Intensity Radiated Pulse and is a game-changing  technology that has been used by the military, now finally available for professional and recreational sonar.

SEIWA CHIRP sonar transmits a longer pulse than traditional sonar, putting more energy into the water column  achieving: 

  • HD resolution and target definition

  • Greater ability to pull targets from the background noise

  • Improved bottom tracking at higher speeds

  • Improved bottom tracking at deeper depths 




ROMEO, the brain of SEIWA navigation systems

ROMEO software is what makes your marine electronics easy to use,
integrating data from different devices with the cartographic info. 

Powerful and flexible, ROMEO is the result of SEIWA's deep knowledge
of both charting systems and marine instruments, gained in more than three decades of activity.

SEIWA ROMEO is constantly improved by our software development team
and our graphic user interface experts, also thanks to our customers' feedback.
