11.2. Deco Setup
Deco Model
By default this will show
“Buhlmann ZHL16C GF”
indicating that the Bühlmann
ZHL-16C with gradient factors
model is being used�
Optional VPM-B and DCIEM decompression algorithm
unlocks are available at an additional cost� If applied,
the deco model item allows the user to change
between the available algorithms�
Conservatism
In technical dive modes conservatism can be adjusted
in either the GF or VPM model�
For a more detailed explanation of their meaning for
the GF algorithm, please refer to Erik Baker’s excellent
articles: Clearing Up The Confusion About “Deep
Stops” and Understanding M-values� The articles are
readily available on the web�
VPM-B has conservatism settings from 0 to +5, with
higher numbers being more conservative�
