Introduction
The Cobalt Diving computer is the first of a new generation
of computers that are easy to use, intuitive and easy to
read. The menu-driven interface is self-explanatory at
every level and can be mastered in just a few minutes. In
spite of its simplicity it is immensely powerful and offers
many sophisticated functions to the advanced user.
The full color LCD display is easy to read, sharp and
bright, with high contrast, and is very energy efficient for
long battery life.
The lithium ion battery is built into the case. It can be
quickly recharged with the AC charger or slow charged by
plugging into the USB port of any PC. It will provide 40-50
hours of dive time between charges and many months of
standby power. If capacity diminishes after several years
of use, replacement can be done by the factory or an
authorized Atomic Aquatics Dealer.
The on board rapid response 3D digital compass makes
underwater navigation simple. Set a course and go.
Unlike most digital compasses, it will remain active until
you choose to turn it off. Crucial dive information is
always displayed.
The Cobalt includes a high pressure quick disconnect that
allows the Cobalt to be removed and carried separately
from your regulator system.
The Cobalt is a multi gas computer that can be set for any
Air/Nitrox mix to 99% O2. Up to 6 mixes can be preset for
easy switching, including gas switches underwater.
The dive log and planner are powerful tools that allow the
easy interactive planning of almost any dive, including
repetitive and multi-day diving. The logbook will store up
to 600 hours of detailed dive profiles in memory.
The Algorithm used in Cobalt is the Recreational RGBM
(Reduced Gradient Bubble Model) created exclusively
for Atomic Aquatics by Dr. Bruce Wienke. The RGBM is
designed to cover a wide spectrum of diving activities
such as bounce, altitude, decompression, repetitive and
multi day. RGBM is a dual phase model that combines
the dissolved phase (Haldane) and free phases (Bubble).
Physiological factors such as age and exertion level
may be input by the user. Additional settings are also
provided to set the conservatism level. Visit our website
www.atomicaquatics.com for more information.

Warnings
WARNING
Before diving, you should have the proper training from
a qualified instructor and obtain a certification from a
qualified training agency. No computer is a substitute for
proper training.
WARNING
Read this manual carefully before diving. It is imperative
that you fully understand the functions and displays of
the dive computer and that you are both proficient in and
familiar with their use prior to diving. The improper use of
this computer may lead to serious injury or death.
WARNING
The gas mixes for enriched air nitrox will not accept
fractional percentage values of oxygen concentration.
You should always round down when editing a gas mix in
the Gas/Tank Settings Menu. For example, a gas mix of
32.6% oxygen should be entered as 32%. Rounding up
will affect decompression calculations which could lead to
decompression sickness.
6
WARNING
This computer is for recreational use only. The computer
is not designed for commercial or professional diving, the
demands of which may exceed your and the computer’s
limitations. Exceeding these limitations may cause serious
decompression sickness or other injuries, including death.
WARNING
There is always a risk of decompression sickness on any
dive regardless of whether you follow dive tables or a dive
computer. In order to lessen the risk of decompression
sickness, you should always dive well within the exposure
limits provided by this computer. If you experience
symptoms of decompression sickness, seek medical
attention immediately!
WARNING
Before diving, make sure the battery is charged to allow
diving time well in excess of your planned dive. Atomic
recommends that you not dive with a battery status of less
than 25%.
Warnings
WARNING
Do not dive without activating the computer. Before
entering the water, you should ensure that the display
is functioning properly, that you have reviewed the
information in the PreDive Check menu, and have selected
the Ready to Dive option. If you feel the computer is not
functioning properly or that the information contained in
the display is incorrect, do not dive.
WARNING
You should never share or trade your dive computer
during a dive. Your computer gathers information
during a dive that is applicable only to you. If you
share or trade your computer with another diver, your
decompression limits will be inaccurate which may
cause decompression sickness.
WARNING
You should never dive with enriched air nitrox unless
you have personally verified the oxygen percentage and
entered the proper value into the Gas/Tank Settings
menu of your dive computer. Failing to verify the oxygen
percentage or entering the wrong value could subject you
to decompression sickness.
WARNING
Always dive with back-up instruments. Even when using
a dive computer, you should always carry a submersible
pressure gauge, a depth gauge, and a watch or other
timing device.
WARNING
You should never fly after diving until you verify that the
No Fly Time reads 0:00. Flying during the No Fly Time can
result in decompression sickness.

Compass Recalibration Procedure
Turn on the computer, go to Main Menu, Settings, Calibrate
Compass.
Step 1. Orient the Cobalt along an estimated North-South
direction. Press SELECT to
start calibration. Step 1 will
begin flashing. Rotate the
Cobalt in a North-South plane
until Step 1 stops flashing
and Step 2 begins to flash.
Step 2. Turn 90 degrees and
point the Cobalt East-West.
Rotate on its lengthwise axis
on the east-west plane, until
Step 2 stops flashing and the
compass appears.
Check the compass function
and repeat if needed. If
satisfied, select the Save
button.
Exit the calibration screen
using the BACK button.
Avoid exposing the Cobalt to strong magnetic fields. These can
alter the compass calibration. Note that diving near large metal
masses may alter the accuracy of any compass.

Battery
Your Cobalt uses a rechargeable Lithium Ion battery that is sealed inside the case. Check the battery level (the charge level is
displayed in the Main Menu) and fully charge the battery before the first use and occasionally afterwards. Best battery life will
come from keeping the battery charged. A full charge will last for approximately 40-50 hours of dive time (depending mostly
on screen brightness settings). A battery warning indicator will appear on the dive display if the battery charge is below 20%.
This charge level should still be sufficient to complete several average dives.
On the surface, The Cobalt display will automatically go dark after 5 minutes to conserve power. Press the SELECT button
to wake the display. The Cobalt is never really turned completely off, but has various sensing modes depending if the Cobalt
is wet, or in the “Ready to Dive” screen. It will wake automatically if it is submerged in water and will start a dive if it senses
pressure. However, we strongly recommend that you use the Pre-Dive Check function to ensure your settings are correct, and
manually select the “Ready to Dive” screen before entering the water.
If the Cobalt 2 becomes completely discharged and will not wake, it can be recharged using either the A/C or USB charging
source. However, if you utilize a USB source you will need to perform a manual reset by holding both the SELECT and BACK
buttons down for at least 11 seconds. The A/C charger will provide an automatic reset, and will charge more rapidly. You will
need to reset the time and date (page 14). On powering up again, the Cobalt will return to the time as of the end of the last
dive. Your logged dives, decompression status, and other personal information are preserved and will not be affected by loss
of power. The battery will last several years of normal use before gradually diminishing in capacity, and can be replaced by the
factory or an authorized Atomic Aquatics Dealer.
Charger set-up
The Cobalt can be charged with either the AC quick charger (about 2 hours to full charge) or from a USB cable connected to a
computer (about half the speed of AC charging). The AC charger will automatically select 110 or 220v AC. Plug the end of the
charger cable into the charger/USB adapter. Plug the charger into an AC outlet and the adapter into the bottom of the Cobalt.
The adapter has 2 sides, make sure you insert it into the side nearest the charge method you selected (AC charger or USB).
Confirm charging by going to the main menu. The display will say “charging”. If the battery is either too hot or too cold to
charge properly the message “Charge Stopped” will display until the temperature is within an acceptable range.

High Pressure Hose and Quick Disconnect
The Cobalt is supplied with a lightweight, small diameter
high pressure hose that is both flexible and highly durable
(maximum 5000 psi (344 Bar) working pressure). The
smooth outer covering is UV resistant and will not abrade
or collect sand or debris. The quick disconnect feature
allows you to easily disconnect the Cobalt from the high
pressure hose and regulator system for separate transport
or storage.
Important Note: Always turn the air pressure off
and depressurize your regulator before attempting to
remove or connect the Cobalt to the high pressure
quick disconnect. It will be very difficult to connect or
disconnect if there is pressure in the hose.
Initial set up
Note: We recommend initial set up and check be done
by an authorized Atomic Aquatics dealer.
1. To assemble the hose to your regulator, first identify
the High Pressure port on your first stage you wish
to use (marked HP). Remove the plug, and install the
threaded end (7/16-20 thread) of the hose. Screw in
the hose fitting hand tight, then snug it securely with
a wrench (9/16"). Do not over tighten or you may
damage the threads (maximum 40 inch/pounds).
2. Connect the Cobalt to the quick disconnect fitting.
Unscrew the large plastic locking ring towards the
hose so the end is flush with the end of the metal
quick disconnect fitting ( Fig. 1). Push the quick
disconnect onto the Cobalt and twist 1/4 turn
clockwise to lock it in place (Fig. 2). Gently screw the
plastic locking ring up against the base of the Cobalt
to keep it in place (Fig. 3).
3. Connect the regulator to your tank and slowly turn the
air on. Check for leaks by listening and submerging
the hose fittings in water.
4. Press the Select button to wake the Cobalt and go to
the dive screen to check the air pressure. Upon initial
pressurization it will take approximately 20 seconds
for the air pressure to display.
5. To remove the Cobalt from the quick disconnect,
depressurize the regulator, unscrew the locking
ring, push in and turn the disconnect 1/4 turn
counterclockwise to release. Replace the rubber
protective cap on the high pressure inlet of the Cobalt
when not in use.
