& Plath Tide Clock Instructions
OPERATING INSTRUCTIONS:
To Set Time:
Insert Battery. To advance hour and
minute hands, turn knob counter-clockwise. To reverse, turn clockwise.
To Set Tide:
At the
appropriate time, set the tide hand to high or low tide using the
adjustment knob. On screw bezel models (such as the Atlantis), you must
unscrew the bezel by turning it counterclockwise, and then gently lean
the clock forward to expose the adjustment knob.
NOTE 1:
It is normal for the tide hand to have some "play" to it. This allows
for proper rotation of the hand.
NOTE 2: Tide fluctuations (high and low
tide) vary from one given place to another. The tide hand therefore
will indicate high and low tide at a particular place or area only.
Official Tide Tables - available a
Harbor authorities, etc. - will supply the exact time of full or high
tide. High and low tides have a fluctuation rhythm between 12 and 13
hours. Therefore, the tide indicator will show average values only,
which for general requirements will be fully satisfactory.
This tide
schedule is geared to tides for the east coast of North America. They
will not accurately depict tides for the West coast. It should be noted
that other variable such as wind, atmospheric pressure, the relative
position of the moon, and the elliptical pattern of the sun will affect
the tide slightly.
These
phenomenon least affect the tide at the time of the full moon. For this
reason, the time of the full moon and to a lesser extent, the new moon,
are generally the best times to set your tide clock. Even though you
may experience some slight variations during the days to come, you will
find that they will "average out" and by the time of the next full
moon, your tide clock will accurately depict the correct time of flood
and ebb stages.
CAUTION:
For the above reasons, if the exact time of tide stages is essential
for navigation, etc., we suggest you consult a tide table
