Alternate Method for Setting the Secondary Tide
Important Note: While the following method may be the most practical way to
set the Tide for the second location it is not the most accurate. See “Setting the
Secondary Tide” (page 11) for the most precise method for setting the second tide.
1. Once the High/Low Tide Indicator is set at your home location you can set the
High/Low Tide Indicator at a second location (a destination port, for example).
2. Refer to a Tide Chart for the secondary location and determine High Tide for
today.
3. Determine the difference in hours and minutes between High Tide at the pri-
mary location and High Tide at the secondary location.
4. Rotate the bezel so that the High Tide indicator (on the bezel) is positioned to
reflect the difference between the High Tide in the primary location and High
Tide in the secondary location in minutes and hours. (example: if the High Tide
in the primary location is 7:34 and the High Tide in the second location is 8:34,

Reading the Secondary Tide
1. Once the Tide Indicator Hand is set for the primary location and the bezel is
set for the secondary location, you can begin tracking the tide in your sec-
ondary location (Note the illustration on page 3 which shows the secondary
location High and Low tide indicators on the bezel).
2. The tide in the secondary location should be read solely from the markings
on the bezel. The tide indicator hand will indicate two High and two low
tides in approximately a 24 hour and 50 minute period.
3. Note that four triangles on the bezel are blue and four are red. As well there
are blue numerals (4 and 2), and red numerals (4 and 2). When the Tide
Indicator hand is between the blue triangles or blue numerals, the tide is
rising. When it’s between the red triangles or red numerals the tide is falling.
4. Both the red and the blue numerals (4 and 2) indicate the approximate num-
ber of hours before the next High Tide and Low Tide respectively. The trian-
gles indicate interval hours relative to the 4’s and 2’s.
