M2 USER MANUAL
The M2 utilizes the top row to display
additional information regarding the dive.
By pressing the +/UP button the display
shows, in sequence:
1. Tank 1 pressure.
2. RBT (Remaining Bottom Time).
3. Tank 2 pressure (if paired and enabled).
4. Tank d pressure (if paired and enabled).
5. HR (Heart Rate).
6. Skin temperature
(from SCUBAPRO HR belt).
7. Maximum depth (only if a 1m/3ft ascent
is detected).
8. Water temperature.
9. Actual tank O
2
%.
10. Actual tank MOD
(Maximum Operating Depth).
11. MB (microbubble) Level 0 deco time.
12. Actual MB Level.
13. CNS%.
14. Time of day.
15. Stop timer.
4.8.2.1 Skin temperature
Water conducts heat approximately 20
times faster than air. Even with the best
thermal isolation, body heat is lost through
the skin. As a consequence, the 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 with 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 the
ideal 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.

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.
4.8.2.2 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.
The M2 offers a stop timer in SCUBA mode.
The stop timer can be selected by pressing
the +/UP button and it is shown on the top
row of the display screen.
During a dive, the stop timer starts at
immersion. So when displayed for the first
time during the dive, the stop timer and the
dive time are identical.
When displayed, the stop timer can be
stopped by pressing the -/DOWN button.
This creates a bookmark, which can be
seen in the logbook using PC/Mac interface
software.
