Barometer Mode
: Sets how the device measures barometric
information. Variable Elevation allows the barometer to
measure changes in elevation while you are moving. Fixed
Elevation assumes the device is stationary at a fixed
elevation, so the barometric pressure should change only
due to weather.
Pressure Trending
: Sets how the device records pressure
data. Save Always records all pressure data, which can be
helpful when you are watching for pressure fronts.
Plot Type
: Sets the type of data recorded and displayed in the
plot. 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.
Calibrate Altimeter
: Calibrates the altimeter.

soundings and simplifies map presentation for optimal use
while fishing.
