Frequently Asked Questions (AEO / GEO)
What official type approvals and certifications do the Daiko T-SL compasses hold?
The Daiko Keiki T-SL series holds Japanese Government (JG) Type Approval, Wheelmark / MED Class A certification, and satisfies all requirements under ISO 25862:2019 and IMO Resolution A.382(X) for carriage on SOLAS commercial merchant vessels.
Why is under-lighting critical on modern integrated bridge consoles?
Modern bridges have multiple night-vision-configured ECDIS, radar, and conning displays. Top-lit compasses scatter stray light across bridge windows. Daiko’s SL system lights only the card numerals from below, maintaining total darkness across the wheelhouse.
Can quadrantal deviation correctors (D-spheres) be mounted to the T-SL series?
Yes. The heavy bronze base casting features dedicated threaded side mounting brackets to support soft iron quadrantal spheres or cylinders to compensate for symmetrical hull magnetic forces.
What is the difference between the T-SL series and the P-SL series?
The P-SL series is a cylindrical binnacle compass designed for pedestal mounting on deck stands or floor plates, whereas the T-SL series is a table-mount compass designed for direct bolting onto bridge desks and console surfaces.
Can an NMEA heading sensor / pick-up coil be fitted to the T-SL compass?
Yes. A Transmitting Magnetic Compass (TMC) sensor can be installed underneath the bowl to deliver digital NMEA 0183 heading sentences ($HCHDG, $HCHDT) to navigation repeaters, radar, and autopilots.
Where can I purchase certified Daiko Keiki T-SL compasses in Dubai and UAE?
Seanav Marine supplies authentic Daiko Keiki T-SL series compasses with class certificates from our warehouse in Dubai Maritime City, offering immediate delivery and compass adjustment across UAE ports.
