3.2.3.1 Total Apnea exercise depth
To provide a scale of total pressure changes
during an Apnea dive session, the A1
includes a total depth counter. By pressing
the +/UP or -/DOWN buttons you can set
the total depth counter from 100m/300ft
to 1000m/3301ft, and save the setting
by pressing the SEL/ESC button. When
your depth total has been reached the A1
noties you at the surface with an audible
tone and a blinking “no dive” symbol to let
you know it’s time to end the session and
take a break.
3.2.3.2 Surface interval factor
Apnea diving organizations provide various
recommendations regarding surface
intervals between dives based on dive
times or depths. The A1 integrates a
surface interval counter which employs
simple multiplication for determining the
surface interval in seconds. The A1 uses the
following formula to make this calculation:
Surface interval before the next dive =
pressure (depth) * square root of dive time
* SIF.
As a reference, a few values are listed in the
following table:
