divers, the HUD offers both the traditional
GF algorithm and the modern ZH-L16 ADT
MB PMG algorithm.

Up the Confusion" and "Understanding
M-Values," both by Erik Baker.
From the Dive Settings menu, by selecting
Deco Algorithm and pressing-and-releasing
the push-wheel you enter the algorithm
menu.
Here you can select either algorithm.
• ZHL-ADT is the Bühlmann ZH-L16 ADT
MB PMG (the default setting).
• ZHL16C+GF is the Bühlmann ZH-L16C
with the potential of additional
conservatism using Gradient Factors.
As ZHL-ADT is the default algorithm,
switching to the GF algorithm requires that
you rotate the push-wheel to toggle to that
algorithm selection.

A press-and-release of the push-wheel
takes you to a separate confirmation
display.
Another press-and-release confirms that
the algorithm has been changed and
returns you to the Dive Settings menu.

NOTE: Any current tissue saturation
data has to be deleted before you
switch the algorithm. Use the function
desat reset.
If you selected the ZHL16C+GF algorithm
you'll notice that the Dive Settings menu
has changed to enable you to set the two
Gradient Factors (in place of MB level, PDIS
and tank reserve).
• GF Low is the numerical setting
that represents the percentage of
