Service and supply
Koden marine electronics, supplied and serviced
Koden Electronics equipment is common on fishing vessels: a radar on the mast, a dual-frequency sounder at the console, a GPS navigator feeding everything else on the bridge. NAVION supplies, installs and services that equipment in Busan and its ports, Vladivostok and China — new fits, commissioning, fault diagnosis, repairs and spares — with the work planned to finish inside the port call.

Frequently asked
Do you supply and service Koden equipment?
Yes. We supply Koden equipment and spares, carry out installation and commissioning, and service and repair equipment already on board.
Can a magnetron be replaced during a port call?
Usually yes, provided the part is confirmed before arrival. Send the radar model and serial number so the correct magnetron type is identified; the replacement and the performance check afterwards take far less time than waiting for the part to arrive.
Tell us the model and the port call
Send the Koden model and serial number, a photo of the rating plate and your dates in Busan to [email protected], or message us on Telegram.
