measure changes in elevation while you are moving.
Fixed
Elevation
assumes the device is stationary at a fixed
elevation. Therefore, the barometric pressure should only
change due to weather.
Pressure Trending
: Sets how the device records pressure
data.
Save Always
can be useful when you are watching for
pressure fronts.
Plot Type
: Records elevation changes over a period of time or
distance, records barometric pressure over a period of time,
or records ambient pressure changes over a period of time.

Marine Map Settings
Select
Setup
>
Marine
.
Marine Chart Mode
: Selects a nautical chart or a fishing chart.
Nautical
displays various map features in different colors so
