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 different 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.
