Direct Reading of Heading on the Compass Bridge
Remove the hood. Read the heading at the ahead lubber mark of the compass.
The second, aft orientated lubber mark is for officer´s inspection. Add here 180° correction to get the ship´s
heading.
Removing/Attaching of Binnacle Hood
Take hood with both hands
Loosen two knurled knobs
Turn hood and lift
When closing the binnacle again
carefully secure the hood by fixing
the knurled knob!
Maintenance: Guiding surface of hood should be lubricated from time to time.
Taking Bearings (optional only)
REFLECTA/4 includes as standard a steering type compass without a graduated scale on top for taking
bearings. A bearing compass type is an option. So a vane type azimuth device with shadow pin is not included
in the standard range of delivery but can be supplied as extra.
To apply (if a bearing compas type is used) remove the binnacle hood to set up the azimuth device onto the
centre pivot of the upper compass cover glass. Open object (wire) sight vane and ocular (slit) sight vane. Use
the circular peep in the ocular (slit) sight vane for a rough pick-up of the bearing mark. For accurate bearing use
the slit of the ocular sight-vane.
Compass bearing (azimuth) of land marks up tp 30° of elevation:
Read the compass card as illustrated below.
Relative bearing of land marks up to 30° of elevation:
Read the graduated verge ring of the compass at the index of the ocular sight-vane. The scale ring is marked
all-round. If semi-circuar bearings are required subtract 360° from the all-round value for objects port side of the
vessel. The starboard bearings remain unchanged.
Sun or star azimuth by azimuth mirror:
The black mirror at the object sight-vane can be hinged up and down according to the star height. The darkness
is suitable to allow sun observations (before make sure that sun will not dazzle!). Read the bearing as required
at the divided verge ring of the compass or at the compass card. Make sure that the compass is horizontal
balanced. It is not recommended to take bearings of astronomical objects heigher that 45° because each
accidental inclination of the compass will distort the measurement.
