The Galileo HUD Diving Computer – Designed for a revolution in diving.
Welcome to SCUBAPRO dive computers and thank you for purchasing the Galileo HUD.
You are now the owner of an extraordinary partner for your dives. This manual provides you
easy access to SCUBAPRO state-of-the-art technology and the HUD’s key features and
functions. Should you wish to know more about SCUBAPRO diving equipment, please visit
our website www.scubapro.com
IMPORTANT
Before using your SCUBAPRO HUD, please carefully read and understand the Read First booklet that
is included in the package.
WARNING
• The HUD has a depth rating of 120m/394ft.
• At depths between 115m/377ft and 120m/394ft in Dive mode the depth changes color and starts to
blink, and at depths over 120m/394ft the HUD automatically switches to Gauge mode and cannot
be used as a decompression computer for the remaining time of the dive.
• Diving at oxygen partial pressures higher than 1.6bar (corresponding to a depth of 67m/220ft when
breathing compressed air) is extremely dangerous and could lead to serious injury or death.
• Never risk your life on only one source of information. Eventually, every computer has the potential
to fail, so do not depend exclusively upon it and always have a plan for how to handle failures. Use
a redundant dive computer, carry backup tables and depth/time instrumentation.
WARNING
The HUD is delivered in deep sleep mode. Charge it and press the push-wheel to activate it before
the rst dive.

GALILEO HUD USER MANUAL
The HUD is a technologically-advanced
heads up display dive computer designed
to provide you with accurate depth, time,
gas and decompression information.
Your HUD user manual is divided into 6
main sections.
Introduction to the HUD. This section
provides an overview of the HUD computer
and describes how to mount the HUD to a
mask, as well as its operating modes and
main functions when on the surface.
HUD settings and menus. This section
goes through the settings of your HUD.
Diving with the HUD. This section takes
you underwater with the HUD, showing you
how to use the HUD as a dive computer
in both Open Circuit and Closed Circuit
Rebreather diving scenarios. It outlines
everything the HUD can—and will—do to
enhance your safety and fun underwater.
HUD accessories. This section briey
describes the HUD’s extras that you can
purchase to get the most out of your dive
computer in all conditions.
Interfaces for the HUD and an
introduction to LogTRAK. This section
describes how to download data, change
settings, and manage your logbook.
Taking care of your HUD. This section
illustrates how to take care of your new dive
computer.
1. INTRODUCTION TO
THE HUD
1.1 Near Eye Technology
The HUD is designed to be mounted on
a diving mask in very close proximity to
the human eye. A person with normal
vision is able to focus on objects starting
from a distance of approximately 20cm.
Since the micro OLED screen of the HUD
is positioned much closer than 20cm,
specially developed optics are required to
be able to read the screen clearly.
These multi-lens optics create an image of
the micro OLED screen at a virtual distance
of approximately 1m. This enables the diver
to read the dive data on the screen and
also maintain eye contact with his or her
surroundings without having to continually
adjust and readjust focus. (The size of this
image is about 30x20cm², enabling it to be
easily read by divers with normal vision.)
WARNING
• The HUD should never be used by divers who
are unable to achieve the proper alignment
of the HUD relative to their eye for optimal
readability (see following section), or who
in any way feel the positioning of the HUD
negatively impacts their comfort at depth.
• Always test for proper readability before
each dive, on the surface, and in a safe
environment.
• If you have issues with your vision or
experience optical problems of any kind,
consult with your doctor before diving with
the HUD. (Note: the HUD can be used with
contact lenses or optical lenses.)
• Always carry a second dive computer as a
backup.

6GALILEO HUD USER MANUAL
1.2 Mounting the HUD on
your mask
The HUD package includes a universal
mask holder which is designed to be
mounted on a dual-lens diving mask just
above the right eye. There are also options
available for mounting the holder to single-
lens masks. These HUD holders attach to
the mask with two cable ties (included).
FNOTE: There are also options available
that enable you to mount the HUD
directly to a SCUBAPRO mask.
You can nd a list of compatible masks
that the HUD can be mounted to with the
universal holder at www.scubapro.com.
1.3 Mounting the holder to
the mask
The following parts are needed to mount
the HUD to your mask. They are all included
in your HUD package:

1. HUD
2. Cable ties
3. HUD holder
4. Ball
5. Protective foil
F
NOTE: We recommend that you
don’t remove the display screen’s
blue protective foil until the assembly
process is complete to avoid scratching
the glass.
The following tools are needed to mount the
HUD to your mask. They are not included in
your HUD package:

GALILEO HUD USER MANUAL
STEPS:
1. Place the HUD holder on your mask
frame to check the positioning of the
holder’s tiny legs (see arrow).
These legs stabilize the holder, preventing it
from shifting horizontally.
FNOTE: The holder must be mounted
correctly on the mask to ensure that
the HUD is positioned correctly in your
line of sight.
2. Shorten the tiny legs as needed
with the side cutters. Guide lines are
provided on each leg edge to make
sure legs are shortened in equal
amounts.
3. Once the legs are trimmed, re-check
the tment.
Repeat this step until proper tment is
achieved.
4. Starting from above the mask, thread
the cable ties down between the hard
plastic of the mask frame and the
silicone, just above the nose pocket.
Direct one cable tie down the left side of the
nose, and one down the right side of the
nose. Once completed, double-check that
the cable ties are properly routed.

8GALILEO HUD USER MANUAL
F
NOTE: The correct positioning of the
heads of the cable ties -- knubbed
side facing the inside of the mask,
at side facing outside -- is very
important (refer to the top arrow in the
next magnied picture.) If reversed,
feeding the ends of the cable ties
becomes difcult, and the positioning
of the cable tie heads against the hard
plastic frame can affect the proper
tment of the mask.
5. While the next mounting step is not
necessary for most SCUBAPRO
masks, on a few mask models the
small ball, included in the HUD’s
mounting parts list, can be used to
even out the silicone in the area just
above the nose, eliminating a possible
pressure mark on your face. Please
consult the HUD compatible mask
table to nd out if your mask might
benet from the use of this ball by
going to www.scubapro.com.
If your mask doesn’t require the ball,
proceed to Step 6. If it does, at this time
insert the ball from the inside of the mask,
above the nose pocket at its highest point,
directly under the hard plastic frame. Press
it into the silicone behind the cable ties. The
cable ties should secure the ball and even
out any excess silicone.
6. Thread the cable ties through the
holder from back to front.
Hold the mask and holder in your hand
like in the picture below. This hand
position will also help you to hold the
ball in place if you’re using one.
The holder has 2 slots, one above the
other. The one you will use to thread your
cable ties depends on your mask.
If the bridge of the nose aligns with the
lower point, use the lower slot; if it is at a
higher position, use the upper slot. Please
consult the HUD compatible mask table
available at www.scubapro.com for more
information on which slot is the best for
your SCUBAPRO mask.
7. Thread the cable ties through the
slots (bending the ends a bit makes
it easier to thread). Take care that the
cable ties lie parallel to each other for
appearances sake.

9
English
GALILEO HUD USER MANUAL
8. Place the heads of the cable ties close
to their nal resting position over the
hard plastic frame.
Thread the ends of the cable ties into
the heads and pull tight in a vertical
direction. If you’re using the ball, take
care that it stays in the correct position
while tightening.
Pull the cable ties individually,
alternating each equally. Take care that
the heads of the cable ties stay in their
nal resting positions over the hard
plastic frame while tightening. Both
cable ties should be properly aligned,
parallel to each other and as vertical as
possible.
9. Use the pliers for the nal tightening.
Pull in a vertical direction to avoid
shifting the head of the cable tie. Check
to make sure the holder is strapped
tight and is stable and secure.
10. Use the side cutter to shorten the
cable ties. Cut off as much excess
cable as possible, taking care the
remaining ends are smooth and
unable to penetrate the silicone.
F
NOTE: if you need to replace a cable
tie, use one with the dimensions of
.14x8in (3.5x200mm).

1.4 Mounting the HUD to the
holder
The mounting/adjustment assembly on the
HUD includes a hand wheel, a compression
spring, 4 standard spacers and 1 locking
spacer (with a at spot in its inner circle), all
arranged on the HUD’s stainless steel post.
STEPS:
1. For the initial mounting, unscrew the
hand wheel to the point where enough
of the stainless steel post (and spring)
is exposed between the spacers to
enable it to be inserted into the jaws of
the holder.
At this point the HUD’s mounting
adjustment assembly might look something
like this: closest to the HUD there would be
2 spacers, then an exposed length of
post with compression spring, then 3 more
spacers, and at the end, the hand wheel.
2. Insert the HUD into the holder and
tighten the hand wheel. As you tighten
the hand wheel the spacers will seat
themselves into the indents in the
holder’s jaws.
3. Rotate the HUD screen to where it can
be viewed through the mask lens. Fix
its position by further tightening the
hand wheel.
4. Put on the mask just like if you were
preparing to go diving and check
the position of the HUD screen. You
want to be able to comfortably see
the complete screen. If it is out of
alignment with your line of sight, you’ll
need to make some adjustments.
The sample in the picture shows that the
HUD has to move to the right (purple arrow)
in order to align with the diver’s line of sight.
That means the distance between the HUD
and the holder needs to be reduced. This
can be easily accomplished by shifting the
position of the spacers.
(If the HUD has to be moved to the left –
orange arrow – the shifting of spacers
would be done in the opposite direction.)
5. Remove the HUD from the mask.
Unscrew the hand wheel again, but
this time remove it completely from the
HUD mounting/adjustment assembly.
6. Remove the locking spacer (the one
with the at space in its hole), the rst
group of standard spacers, then the
compression spring. This leaves the
spacers closest to the holder.
