MANTIS USER MANUAL
1. INTRODUCTION TO
MANTIS
Your MANTIS User Manual is divided into
the following main chapters.
1 Introduction to MANTIS. This chapter
provides an overview of the MANTIS
computer and describes its operating
modes and functions when on the surface.
2 MANTIS as a watch. This chapter
describes MANTIS when it is used as a watch.
3 MANTIS as a dive computer. This
chapter describes all settings and functions
of MANTIS as a dive computer and takes
you underwater with MANTIS. It’s about
everything MANTIS can and will do to
enhance your safety and fun underwater.
4 MANTIS accessories. This chapter
briefly describes the extras that can be
purchased as additional options to get the
most of your dive computer in all diving
conditions.
5 MANTIS PC interface. This chapter is
about linking MANTIS to your PC/MAC. It
describes how to change settings, plus how
to download and manage your logbook.
6 Taking care of MANTIS. This chapter
describes how you should take care of
MANTIS after underwater adventures
and also summarizes the main technical
information of this instrument.
MANTIS is a technologically-advanced
instrument that can accompany you
during your underwater adventures while
providing you with accurate depth, time and
decompression information. On the surface its
size makes it your ideal everyday companion.
With features such as wake-up alarm, stop
watch, barometer, altimeter and swim mode,
MANTIS can tackle almost every possible task.
The buttons allow you to initiate operating
functions, make setting changes and
access menus while on the surface. During
the dive they set bookmarks, show further
information on the computer screen and
activate the backlight.
It is time to dive into the details now. We
hope you will enjoy getting to know your
new computer and we wish you many
happy dives with MANTIS.
1.1 Battery
MANTIS uses a CR2032 battery which is
available at your Authorized SCUBAPRO
dealer. MANTIS will alert you when the
battery is approaching a critical discharge
level by displaying the battery symbol.
A steady symbol means that the battery is
low, with some reserve left. At this point the
backlight cannot be activated. If the symbol
blinks the battery level is dangerously low
and the backlight and alarm tones cannot
be activated; diving is not recommended
before replacing the battery.
6
MANTIS USER MANUAL
WARNING
Starting a dive when the battery symbol is
blinking can cause the computer to fail during
the dive! Replace the battery before any diving
activity if the blinking battery symbol appears.
When the ‘do not dive symbol’ appears along
with the battery symbol MANTIS cannot be used
for diving before a fresh battery is installed.
Please refer to the chapter on Checking
the battery status for details how to
manually trigger the battery level check.
WARNING
Replacing the battery requires opening the
electronic compartment of MANTIS. You must
take extreme care when performing the battery
change operation in order to ensure the water
tightness of the watch. Failing to do so will
cause the watch to ood during your next dive
and permanently ruin it. Damage to MANTIS
due to an improper battery replacement is not
covered by warranty. We strongly recommend
having the battery change operation be carried
out by your SCUBAPRO dive retailer.
See chapter Replacing the battery in
MANTIS in this manual for information on
how to replace the battery.
2. OPERATION MODES
The reference point for any description
of MANTIS as a watch is the main time of
day display. This is the display in which the
current time is shown on the middle row.
The upper row shows the day of the week
and the date. The example below shows
Thursday, 20th of March and the time is 34
minutes and 9 seconds past 11 o’clock.
The different menu modes are written at the
display like for example: “Watch set”. Each
mode may have sub functions and menus.
You can scroll between menus by pressing
+/UP or -/DOWN buttons. Note that
although Menu is written on the display,
you still have not activated the mode. By
pressing the SEL button you activate the
mode and get into the sub menus.
The modes are grouped and described in
this manual in three chapters:
1. MANTIS as a watch
2. Menus and functions at the surface
3. MANTIS as a dive computer
The following chart describes the main
menu structure.

The laps can be marked by pressing -/
DOWN button when stopwatch is counting.
By doing so the display will freeze for 5
seconds and MANTIS shows the lap time.
Counting will continue automatically and
the lap counter will show the number of
laps at the bottom of the screen.
When stopwatch is stopped you can
review your lap times from the memory by
pressing -/DOWN button.
By pressing SEL button you can exit the
stopwatch and return to the Stopwatch
menu.
F
NOTE: You can leave the stopwatch
actively counting or you can leave the
stopped time on the display. The status
will be stored in memory allowing you
to continue from the same display at a
future time.
F
NOTE: Stopwatch has a 30 minute
timeout before reverting to normal watch
display. However, the timeout does
not stop the stopwatch function. You
can return to the stopwatch menu and
continue with the time taking task just as
you did before the timeout happened.
3.2.2 Reading the altitude, barometer
and temperature values
In the altitude menu the current altitude is
calculated from the barometric pressure
and is shown on the middle row. The
current temperature is shown on the
bottom row. The current altitude class is
shown on the top row.
F
NOTE: barometric pressure is a variable,
changing with weather and atmospheric
pressure at that particular elevation. The
Dive algorithm uses Altitude Classes
which are directly derived from the
barometric pressure. Altitude is counted
from the current barometric pressure and
it is therefore a relative value.
15
English
MANTIS USER MANUAL
By press and hold the -/DOWN button the
display changes and shows on the bottom
row the barometric pressure at sea level.
Or, press and hold the +/UP button and
you get the barometric pressure in mbar
at current altitude. This Barometer feature
allows you to foresee the approaching
weather in the upcoming hours if your
altitude remains the same.
The altitude can be adjusted when current
elevation is known by pressing the SEL
button. The altitude value will start blinking.
By pressing +/UP or -/DOWN buttons
the value can be adjusted in 10m/50feet
increments. Adjusting the altitude elevation
has no effect on the Altitude Class.
F
NOTE: Different combinations m&˚C,
Ft&˚C, m&˚F or Ft&˚F can be selected
from the Dive mode menu: Units.

MANTIS USER MANUAL
You can plan your next dive based on your
body’s nitrogen saturation. The planner is
also using the following information.
1. Selected oxygen concentration.
2. Enabled gases (multi gas diving).
3. Selected water type.
4. Selected microbubble level.
5. Water temperature of the most recent
dive.
6. Altitude range.
7. Status of saturation at the time when the
planner is started.
8. Observance of the prescribed ascent
rates.
F
NOTE: When MANTIS is in GAUGE or
APNEA modes the Planner is disabled
and this is indicated by showing OFF in
this menu.
By pressing the SEL button in the planner
menu you will get into the Planner directly
or an after repetitive dive to the surface
interval setting.
In case you plan to make a second dive
during the desaturation phase, you must
start the Planner by inputting the time you
would still stay at the surface.
By pressing the +/UP or -/DOWN buttons
you can set the time in 15 minutes
increments. The prohibited altitude is
shown on the top row. By increasing the
surface interval the allowed limit will reach
maximum (level 4). To learn more about
altitude diving with MANTIS refer to the
chapter Altitude diving.
In case MANTIS is displaying the no-dive
warning, the duration of the warning itself is
displayed as recommended surface interval
for planning purposes (rounded up to the
nearest 15-minute increment).
When the surface interval is given or if you
have no remaining desaturation left, the
planner will start blinking the depth. By
pressing +/UP or -/DOWN you can set the
depth in 3m/10feet increments.
Minimum depth for planning is 9m/30feet.
The no decompression dive time for given
depth is shown on the middle row.
17
English
MANTIS USER MANUAL
The gas O
2
content is shown on the bottom
row until the 1% CNS for the planned depth
is reached. After that the planner shows the
CNS% on the bottom row.
The planner allows only depths according
to maximum ppO
2
. The gas oxygen content
and maximum ppO
2
settings are given on
the dive set menu (described in chapter
Set Gas 1, 2 or d).
WARNING
if you have set the ppO
2
max to OFF, the
planner will allow depths up to maximum of
120m/394ft. Air/nitrox dives with high ppO
2
are extremely dangerous and can lead to fatal
injury. Be aware that exposures to high ppO
2
will lead the CNS clock value to exceed the
maximum recommended 100%.
F
NOTE: If MOD is shallower than
9m/30feet, planning is not allowed
and information LO MOD is shown.
By pressing SEL for planned depth the
dive time starts blinking. The start point
(minimum now) is the no decompression
time. By pressing +/UP or -/DOWN buttons
you may change the time in 1 minute
increments. Decompression time and total
ascent time are shown on the middle row.
By pressing the SEL button the planner will
exit and you will get back to the main menu.
3.2.4 Reading the logbook
You can check the main information about
your dives from the Logbook of the MANTIS.
The first page shown is the dive history.
On the display above, the MANTIS has
38 dives and a total of 43 hours of diving
stored in the Logbook, with the deepest
dive at 32.2 meters and the longest dive
time of 63 minutes.
