Altimeter

• Altimeter tracks you vertical movement
• Altimeter Resolution: 1m (3ft)M
• easure current altitude, relative altitude, total upward altitude and downward altitude and it can save the records automatically.E
• ntering into altimeter mode for 3 minutes, our watch can record altitude automatically, and can save up to 30 records.

Barometer & Weather Forecast

• Barometer tells the trend in air pressure
• Barometer Range: 300hPa -- 1100hPa,
• Barometer Resolution: 1hPa(0.01inHg)
• This watch can predict weather by the changes of the pressure trend, Pressure downward means going to be bad weather, and pressure upward means going to be good weather.

Compass

• Compass points the way
• Compass Resolution: 1°
• While using compass, please keep the watch in the horizontal position and also far from the magnetic fields. It often needs to calibrate the compass and set the declination before measuring orientation.
• Considerations: 1) Please check the calibrate before using; 2) Please set local magnetic before using.
