FUTURE MODE FEATURES
When viewing the time in future mode, the –
and + buttons can be pressed to scroll ahead or
backward day-by-day. The time scrolled to will
remain set. This is useful for preparing for a
future fishing trip and planning the best times
to fish.
No weather prediction or barometric air
pressure can be viewed when in future
time mode.
BAROMETRIC AIR PRESSURE
The built-in barometer senses the changes
in barometric air pressure every 15 minutes,
even when the unit is "off". When viewing the
current air pressure, the chart on the top of the
LCD will display the air pressure history for
the past 24 hours. Each column, right to left,
represents one hour in the past. Each dot
represents a change in air pressure, up or down,
relative to the current air pressure, or "0 Hr".
To read the graph, follow the chart from left to
right. The graph will increase when the air
pressure rose, and decrease when the pressure
fell. The pressure trend for the past 6 hours is
the most useful for short-term weather
forecasting.
