Altitude Diving

At higher altitudes, the atmospheric pressure is lower, and your body contains a larger amount of nitrogen than
it would at the start of a dive at sea level. The device accounts for altitude changes automatically using the
barometric pressure sensor. The absolute pressure value used by the decompression model is not affected by
the altitude or the gauge pressure displayed on the watch.
