favorite location or beach break is

locations, you may wish to add it.
To do this, you will need to know
the time difference between the high
tide at your favorite beach and the
high tide (for the same day) at
the closest pre-programmed beach.
This time difference information is
usually illustrated on tide calendars
or local tide charts, and is indicated
for example as (+ or -) 10, 20 or 30
minutes between two beach
locations. For example, suppose
your favorite beach break is Malibu,
which is not pre-programmed in the
watch, and your local tide calendar
indicates that Malibu tides are (+10)
minutes, compared to Los Angeles
tides. After entering Malibu as your
favorite beach, you would enter
(+10) as your offset.
