Advanced Free Dive Mode
The GEO provides accurate depth and time with an amazing 1-second sampling rate
for subsequent PC download and analysis. Dive Time is displayed in seconds and
minutes. Custom audible alarms include Elapsed Dive Time, Countdown Timer and
(3) Independent Max Depth Alarms. The GEO is the first Free Diving Computer
to calculate and track Nitrogen Tissue Loading, allowing you to switch between
SCUBA dives and Free Dives on the same dive day.
Advanced
Wristwatch Functions
The GEO is an advanced digital wristwatch featuring a 1/100 second
chronograph (stopwatch) with lap timer, 24 hour countdown timer, daily alarm,
alternate time zone with date, 12/24 hour clock, and OceanGlo® Backlight.
Dive
Time Remaining
Dive Time Remaining provides a 'real' number in minutes, considering Nitrogen
and Oxygen absorption, and automatically displays whichever allows less time.
Oversized
Digits
Take the Oceanic challenge: When shopping for a new dive computer, compare the
displays. When it comes to viewing critical information, which would you rather
see at 100 feet?
Audible
Alarms with Flashing LED Warning Light
The GEO features a variety of system and user-customized audible alarms, alerting
you to situations that pose a potential danger, or simply serve as a convenient
reminder.
Audible
Alarm Acknowledgement™
Have you ever had difficulty hearing your computer's audible alarm? Perhaps
that little beep signifying a potentially dangerous situation was timed perfectly
with your exhaust bubbles rushing past your ears. Or maybe it seemed insignificant
as that huge manta ray soared overhead. You won't miss the GEO's audible alarm.
Once triggered, the alarm will sound continuously for 10 seconds. We know what
you're thinking. "That's nice, I'll definitely hear the alarm, but isn't
that going to annoy me and everyone else in the water?" We thought of that
too. The alarm's job is to get your attention so that you look at the computer.
Once it does that, simply press the button and it will stop. You're a responsible
diver and the GEO treats you that way.
Air
or Nitrox
The GEO acts simply as an 'Air' computer until you tell it otherwise, whether
that is this weekend or 2 years down the road.
Oceanic
Personal Dive Computer Algorithm
Decompression theory can be trusted only as far as it has been demonstrated
by actual test dive data. In 1987 a unique series of experiments were conducted
by Diving Science and Technology (DSAT). Commissioned by the Professional Association
of Diving Instructors (PADI), these Doppler ultrasound monitored human experiments
conducted by Dr. Michael Powell produced the most comprehensive data set that
exists for recreational divers to this day. These data were used to validate
the PADI Recreational Dive Planner and are the basis of the algorithm used in
all Oceanic Personal Dive Computers (PDCs).
Personal
Conservative Factor Adjustment
When the Conservative Factor is set On, the no-decompression limit times are
reduced to values equivalent to those that would be available at the next higher
3000 foot (915 meter) altitude.
"The
Ultimate Adjustable Algorithm"
That's the way divers, instructors and Authorized Dealers refer to Oceanic PDCs.
Our tissue loading bar graphs provide complete control of your margin of safety
for each dive. Want to be a bit more cautious? Make it a personal rule to never
enter into the caution zone; or stay one or more pixel away. Now you can even
program several of our PDCs to do it for you with our patent pending Nitrogen
Bar Graph Alarm; set it once and let the GEO alert you when your bar graph reaches
that level.
No
Deco Safety Stop Prompt with Adjustable Depth and Time
An audible and visual alarm remind you as you approach your programmed no decompression
safety stop depth and an automatic timer counts down to zero. As in any other
dive mode, you still have access to other pieces of information, and there is
no penalty should you choose to disregard the safety stop.
FastSet
User Interface
Speed through menu items and set modes easily and quickly with Oceanic's FastSet
Menu and intuitive button operation.
Date
and Time Stamp
The GEO features time of day on the surface as well as underwater for quick
reference. Time and date stamp also helps you to easily identify specific dives
in Log Mode or PC download memory.
Alphanumeric
Display
An alphanumeric "Message Box" is incorporated in the upper portion
of the GEO display to provide text and numeric readouts in simple, unambiguous
terms. Imagine beginning an ascent and as the ascent speed increases hearing
a warning beep from the GEO as the message box alerts with the words "TOO
FAST" while the red LED warning light flashes.
Automatic
Altitude Compensation
The GEO automatically compensates for altitude dives up to 14,000 feet, giving
adjusted no-decompression times and depths. The GEO even automatically recalibrates
the depth displays for freshwater instead of seawater above 2,000 feet.
Diver-Replaceable
Batteries
The GEO features a diver replaceable battery. This can be a real trip-saver
on board a live-aboard boat!
Battery
Hot Swap
Should you be in a tight spot between dives, the "hot-swap" feature
allows you to change batteries between dives while maintaining all calculations.
24-Hour
Fly Countdown and Calculated Desaturation Time
The GEO features both a 24-hour countdown timer and calculated Desaturation
Time, the theoretical time required to off-gas all residual nitrogen at sea
level.
Depth-Dependent
Ascent Rate
The GEO features a depth-dependant ascent rate, allowing increased rates at
deeper depths and providing additional safety as you near the surface.
SmartGlo®
Backlighting
Want to verify your set mode options before your night dive? Press the side
button to activate the backlight and go ahead! A small photo-sensor in the face
of the GEO analyzes the intensity of ambient light each time another button
is pressed. If it’s dark, SmartGlo backlighting will be there for you when
you need it, and it will preserve battery life when you don’t.
