Altitude Compensation/Surface Pressure Adjustments
The KAON does not have a water sensor that can sense whether it is in the water based on “wetness”.
Instead, your KAON continuously tracks atmospheric pressure to determine the surface pressure at the
start of your dive. When it senses a sudden change in ambient pressure, it understands that you have
entered the water and that a dive is beginning.
Your KAON can generally distinguish between a sudden change in pressure caused by water entry, vs.
other types of sudden changes in pressure, such as a plane taking off, or driving up a mountain.
This method of surface pressure detection has proven quite reliable, but it is always possible to trick
your KAON, for example:
•
if you place your KAON in shallow and very stable body of water (such as a bucket full of dive
gear being rinsed), your KAON may assume that current surface pressure is more than it is in
reality. If you go diving immediately after this, your depth reading may be distorted.
•
if you increase ambient pressure very quickly after the KAON has adjusted for being at altitude
(e.g. if you were to skydive with a KAON), it might go into a phantom dive, as it will assume
that you have entered the water. In this highly unlikely case, the only solution is to reset your
KAON by removing the battery (please refer to the
details).
You can always check what KAON assumes as the current surface pressure by going to the “Status”
screen (please refer to
