Diving
Dive Warnings
WARNING
• The diving features of this
device are for use by
certified divers only. This
device should not be
used as a sole dive
computer. Failure to input
the appropriate dive-
related information into
the device can lead to
serious personal injury or
death.
• Make sure that you fully
understand the use,
displays, and limitations
of your device. If you
have questions about this
manual or the device,
always resolve any
discrepancies or
confusion before diving
with the device. Always
remember that you are
responsible for your own
safety.
8 Quick Start Manual

• There is always a risk of
decompression sickness
(DCS) for any dive profile
even if you follow the dive
plan provided by the dive
tables or a diving device.
No procedure, diving
device, or dive table will
eliminate the possibility of
DCS or oxygen toxicity.
An individual's
physiological make up
can vary from day to day.
This device cannot
account for these
variations. You are
strongly advised to
remain well within the
limits provided by this
device to minimize the
risk of DCS. You should
consult a physician
regarding your fitness
before diving.
• Do not dive with a gas if
you have not personally
verified its contents and
input the analyzed value
to the device. Failure to
verify tank contents and
input the appropriate gas
values to the device will
result in incorrect dive
planning information and
could result in serious
injury or death.
• Diving with more than
one gas mixture presents
Quick Start Manual 9

a much greater risk than
diving with a single gas
mixture. Mistakes related
to the use of multiple gas
mixtures may lead to
serious injury or death.
• Always ensure a safe
ascent. A rapid ascent
increases the risk of
DCS.
• Disabling the deco
lockout feature on the
device can result in an
increased risk of DCS,
which can result in
personal injury or death.
Disable this feature at
your own risk.
•Violating a required
decompression stop may
result in serious injury or
death. Never ascend
above the displayed
decompression stop
depth.
• Always perform a safety
stop between 3 and 5
meters for 3 minutes,
even if no decompression
stop is required.
Dive Modes
The Descent Mk1 device
supports five dive modes.
Each dive mode has four
phases: dive pre-check,
10 Quick Start Manual

surface display, in-dive, and
post-dive.
Single-Gas: Allows you to
dive with a single gas
blend.
Multi-Gas: Allows you to
configure multiple gas
blends and switch gases
during your dive. This
mode supports one
bottom gas, and up to
five additional gases for
decompression or
backup.
NOTE: Backup gases are
not used in no-
decompression limit
(NDL) and time to surface
(TTS) decompression
calculations until you
activate them during a
dive.
Gauge: Allows you to dive
with basic bottom timer
features.
NOTE: After diving in
gauge mode, the device
can only be used in
gauge or apnea mode for
24 hours.
Apnea: Allows you to free
dive with apnea-specific
dive data. This mode has
a higher data refresh
rate.
Apnea Hunt: Similar to the
Apnea dive mode, but

tuned specifically for
spearfishers. Start and
stop tones are disabled.
