elevation, so the barometric pressure should change only
due to weather.

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.

soundings and simplifies map presentation for optimal use
while fishing.
Appearance: Sets the appearance of marine navigation aids on
the map.
Marine Alarm Setup: Sets alarms for when you exceed a
specified drift distance while anchored, when you are off
course by a specified distance, and when you enter water of
a specific depth.
