Decompression Algorithm; Levels Of Protection; Repetitive Dives; Dives With Surfacing - Seac ACTION Manual

ACTION
If you Reset the Settings, the Computer will automatically start in SCUBA mode.
When the Computer is in Watch mode and you dive without manually
entering dive mode (using the LR button), the Computer will automatically
launch the mode you selected most recently.

Decompression Algorithm

The computer uses the original Buhlmann ZHL-16C Decompression Algorithm,
unmodified.

Levels of Protection

The Action allows you to select 6 levels of protection (conservatism), from 0 to 5.
Level 5 provides the maximum protection.

Repetitive Dives

All dives taken within a 48-hour period are considered "Repetitive Dives" .

Dives with Surfacing

"Surfacing" is defined as the situation in which the diver emerges after having
begun a Scuba type of dive.
Surfacing ends if the diver dives again within a period of fewer than ten minutes
from emerging; beyond this limit the current dive is considered ended.
If you change mixes during the dive and dive again within the 10 minute
Surfacing time, the mix in use is reset to the starting mix.

NDL - NonDecompressionLimit

The "NonDecompressionLimit" is defined as the time that remains at the
current depth and breathing the mix that is currently set to avoid requiring
decompression.
To avoid requiring decompression stops, the time required for the ascent must
be subtracted from the NDL.
