WATER TEMPERATURE: Diving in cold water can
lead to a lower diver core and skin temperature which
can affect the gas exchange rate of the body’s
tissues. The COMMANDER features two modes of
Temperature Compensation, Normal or Reduced.
The COMMANDER progressively makes its nitrogen
algorithms more conservative as the water
temperature declines below 75 degrees F. Above this
water temperature, there is no temperature
compensation. In the Reduced Mode, the algorithms
are made more conservative by approximately one-
half the amount of the Normal Mode. If the diver is
wearing an insulated dry suit and is relatively warm
even in cold water, this temperature compensation
factor may be set to Reduced Mode at the divers
discretion using the Analyst
®
PC software.
MICROBUBBLE: There are several theories
regarding the exact method by which a nitrogen
bubble forms from a microbubble which was formed
from micronuclei. Currently the predominant theory
states that more rapid ascents accelerate bubble
formation. The COMMANDER comprehends and
adjusts for this phenomenon.
USER CONSERVATISM: Current dive computers
cannot tell if the diver is dehydrated, tired, smokes,
overweight, or has some other physical issue that may
require additional conservatism in the nitrogen
algorithm. The COMMANDER allows the diver to
input an added degree of conservatism to the nitrogen
algorithm from 0 to 50 percent in one-percent
increments. This can be done via the Touch Contact
Programming Mode or with the Analyst
®
Personal
Computer Interface.
PREVIOUS DIVE PROFILES: Under some
circumstances, recent dive activity can have an effect
on nitrogen loading, particularly if the diver engages in
inverted profile diving. This occurs when a deep dive
is followed by an even deeper dive. This recent dive
history is used to compensate the nitrogen loading for
the current dive. This can be enabled or disabled with
the Analyst

Personal Computer Interface.
