MANTIS USER MANUAL
WARNING:
During all dives, perform a safety stop
between 3 and 5 meters/10 and 15 feet for 3
to 5 minutes, even if no decompression stop
is required.
Temperature: MANTIS displays the water
temperature during the dive and the
air temperature when on the surface.
However, skin temperature influences the
measurement when worn on the wrist.
Decompression information: when MANTIS
calculates the need for a mandatory
decompression stop, it shows you how
long and how deep your deepest stop is. It
also gives you the total ascent time. Stops
deeper than 27m/90ft and total ascent times
longer than 99 minutes are shown as “- - “.
4.7.1.1 Display configuration during
the dive
Throughout the dive, MANTIS displays the
most important information on the top row:
current depth (left), elapsed dive time (right).
The no-stop or decompression information
is presented in the middle row.
MANTIS utilizes the bottom row to display
additional information regarding the dive.
By pressing the +/UP button the display
shows, in sequence:
1. Maximum depth (only if 1m/3ft ascent
detected)
2. HR
3. Water temperature
4. Actual tank O
2
%
5. Actual tank MOD
6. Actual MB Level
7. MB Level 0 deco time
8. CNS %
9. Time of the day
10. Stop timer
11. Skin temperature
(from SCUBAPRO HR belt)
4.7.1.2 Skin temperature
Water conducts heat approximately 20 times
faster than air. Even with the best thermal
isolation the body heat is lost through the
large skin area and as a consequence body
regulates blood circulation in the skin and at
the extremities to maintain the body’s core
temperature.
Past recommendations to add more
conservatism to cold water dive profiles was
based on the water temperature and/or a
dive suit thermal isolation estimation. Now,
SCUBAPRO has taken the next step in
diving and presents a new patented wireless
technology for measuring the temperature
underneath the thermal isolation layer.
Skin temperature is measured inside the
SCUBAPRO heart rate belt. The heart
rate belt is located at the mid-torso which
is theideal location for estimating skin
temperature independent of the type of
dive suit being worn. The temperature is
modulated to the belt transmission signal
and the dive computer shows and uses this
information in SCUBAPRO’s adaptive dive
algorithm.
The temperature measured inside of the
heart rate belt has a range of +18..36°C
(64..97°F) in 1°C resolution. The SCUBAPRO
heart rate belt can be used with wet or dry
suits.
F
NOTE: Heat vests with a heating
element that overlays the SCUBAPRO
heart rate belt or other active heating
suits cannot be used with skin
temperature heart rate belts.
4.7.1.3 Stop timer
There are many situations during a dive where
a simple stop timer, independent of dive time,
is practical; for example timed tasks on dive
courses or special missions, etc.
MANTIS offers a stop timer in SCUBA
mode. The stop timer can be selected by
pressing the +/UP button and it is shown on
the bottom row of the display screen.
