You’re hiking and take a break when you see a sign with the current altitude. You check your
altitude reading and discover a small dierence between the two numbers. You set the
altitude reference value on your to match that of the sign.
7.3. Using weather trend indicator
The weather trend indicator is located on the upper side of the display. It is displayed in the
TIME and ALTI & BARO modes, providing you with quick reference to check upcoming
weather conditions. The weather trend indicator is comprised of two lines forming an arrow.
Each line represents a 3-hour period. The right line represents the last 3 hours. The left line
represents the 3 hours prior to the last 3 hours. So the line can indicate 9
dierent patterns in
the barometric trend.
Situation 3-6 hours ago
Situation last 3 hours
Dropped heavy (>2 hPa/3hours) Dropping heavily (>2 hPa/3hours)
Remained stable Rising heavily (>2 hPa/3hours)
Rose heavy (>2 hPa/3hours) Dropping heavily (>2 hPa/3hours)
TIP: If the weather trend indicator shows that the air pressure is constantly rising, there is
a higher possibility of sunny weather upcoming. Again, if the air pressure is constantly
dropping, there is a higher possibility of rainy weather.
