ALGORITHM
The DSX utilizes the Bühlmann ZHL-16C algorithm model to calculate nitrogen tissue loading. To create even
greater margins of safety with respect to decompression, a Conservative Factor (via gradient factor settings) as
well as Safety Stops can be included for No Decompression dives.
GF (GRADIENT FACTOR)
Gradient factors are a method for setting decompression table conservatism. The ZHL-16C model predicts maxi-
mum inert gas saturation values that should not result in Decompression Sickness symptoms if the diver were to
ascend further during the dive.
Gradient factors take this further by limiting the diver to ascend only with a fraction (factor) of the algorithm's maxi-
mum allowed gas saturation values.
CONSERVATISM
The DSX offers both Sport and Tec conservative settings.
The Sport option gives the user the choice of 3 settings: Low (90 - 90), Medium (35 - 80), and High (30 - 70).
Increasing the Conservatism setting (Low > Med > High) decreases, the dive time remaining, NO DECO (No De-
compression)/O2 TIME, which are based on the algorithm and used for N2/O2 calculations and displays relating
to Plan Mode will have their values reduced.
The Tec setting adds a technical gradient factor option. This option allows the technical diver to manually select
an appropriate GF High and GF Low setting for the planned dive.
SAFETY STOP
Upon ascent to within 1.5 m (5 ft) deeper than the Safety Stop depth set for 1 second on a No Decompression
dive in which depth exceeded 9 m (30 ft) for 1 second, a beep will sound and a Safety Stop at the depth set will
appear on the Dive Main display with a countdown beginning at the Safety Stop time set and counting down to
0:00.
• If the Safety Stop was set for OFF, the display will not appear.
• In the event that you descend 3 m (10 ft) deeper than the Stop Depth for 10 seconds during the countdown, or
the countdown reaches 0:00, the No Decompression Main screen will replace the Safety Stop Main screen. The
Safety Stop Main screen will reappear upon ascent to within 1.5 m (5 ft) deeper than the Safety Stop depth set
for 1 second.
• In the event that you enter Decompression during the dive, complete the Decompression obligation, then de-
scend again below 9 m (30 ft); the Safety Stop Main will appear again upon ascent to within 1.5 m (5 ft) deeper
than the Safety Stop depth set for 1 second.
• If you ascend to 0.9 m (3 ft) of the surface for 1 second, the Safety Stop will be canceled for the remainder of
that dive.
• There is no penalty if you surface prior to completing the Safety Stop or choose to ignore it.
