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.
24
Dive On-Unit Log Book
The GEO features on-unit data storage capacity for 24 dives. Date and time stamp
makes locating and viewing a specific dive quick and easy .
History
Mode
History Mode displays accumulative information for up to 9999 dives, 9999 dive
hours and the maximum depth achieved. History information is maintained indefinitely,
even if the battery is replaced .
Optional
OceanLog® PC Download and Settings Upload Interface
Oceanic's GEO OceanLog PC Interface is an exquisitely detailed digital dive
log. OceanLog allows you to easily transfer dive data from your GEO to your
PC via a plug-in USB cable. Following download, your dive data is automatically
formatted for easy viewing, sorting, analysis, and printing. Enter location,
dive buddy and your notes and you've instantly created your own digital logbook.
In addition to detailed
dive analysis, the GEO OceanLog PC Interface also allows you to quickly and
easily set most of your user settings and options through your PC.
Gauge
Mode
Divers using advanced breathing gas may utilize the GEO as an advanced air integrated
digital depth gauge and bottom timer with detailed PC Interface.
Split
Set Mode Access
To make easy work of customizing your GEO, our user settings and options are
organized in one of three set mode menus. Set F (FO2) includes all Nitrox settings.
Set A (Alarms) allows you to activate and customize all audible alarms. Set
U (Utilities) includes units of measurement, PC sampling rate, and conservative
factor settings.
USER
SETTINGS AND OPTIONS
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. As your training and experience
grow, the GEO is designed to grow with you, being easily programmed for Nitrox
mixtures from 21% to 50%.
FO2 50%
Default On/Off
Following a Nitrox dive, many dive computers calculate your next dive based
on a "worse-case scenario", mix of 50% Oxygen and 79% Nitrogen should
you forget to reset your actual mix. With FO2 50% Default OFF, your mix remains
at the original set point until you change it again.
Mode
Selection
Activate Digital Gauge Mode for dives conducted beyond the limits of the Air/Nitrox
computer, Free Dive Mode or NORM Mode for Air or Nitrox dives.
Audible Alarm and Flashing
LED Warning Light On/Off
You may choose to deactivate all audible and LED alarms.
Maximum
Depth Alarm
The Maximum Depth Alarm provides an audible warning upon reaching your planned
maximum depth. This is an important safety feature for deeper dives or less
experienced divers, and it comes in handy for rebreather diving where you can
pre-set another level of safety.
Elapsed
Dive Time Alarm
You're on a boat trip and the captain says, "Dive your own profiles, but
be back in an hour - we're having lunch!" Just set your GEO to alert you
when your elapsed dive time reaches one hour.
Nitrogen
Tissue Loading Bar Graph Alarm
Oceanic's trademark nitrogen bar graph design provides the ultimate user-adjustable
computer. Want to be a bit more cautious? Make it a personal rule to never enter
into the caution zone, or stay one pixel away, or - you get the point. Now you
can program the GEO to do it for you. Set it once and let your computer alert
you when your bar graph reaches a pre-determined level.
Dive
Time Remaining Alarm
Dive Time Remaining provides a 'real' number in minutes. This calculation considers
both Nitrogen and Oxygen absorption, displaying whichever allows less time.
With this unique GEO feature, you are able to program an audible alarm to alert
you upon reaching a pre-set number in minutes.
Maximum
PO2 Level Alarm (Nitrox)
When diving Nitrox, do you prefer your maximum PO2 exposure to be 1.2 ATA? 1.6
ATA? Depending on where you learned and your own personal comfort zone, the
answer may be very different from diver to diver. The GEO lets you set your
own limit. Program an audible alarm to sound at the level that you prefer.
Water
Activation On/Off
The GEO automatically enters Dive Mode when the water contacts are wet, and
the unit is submerged past 4 feet. To avoid this when swimming or enjoying other
water sports, simply set Water Activation Off.
Units
of Measurement
Choose between Metric and Imperial settings for date, temperature, depth and
pressure.
Automatic
Safety Stop Prompt with Adjustable Depth and Time
Set the Automatic Safety Stop Prompt On or Off. Set the Stop Depth to 10, 15
or 20 feet and the Stop Time to 3 or 5 minutes.
Personal
Conservative Factor
Set the Conservative Factor On to further reduce your exposure to decompression
sickness.
Backlight
Duration
Would you like the backlight to shut off as soon as you release the button?
Would you rather it remain on for 0, 5, or 10 seconds? We don't need to make
these decisions for you; it's your choice.
PC
Interface Sampling Rate
You have the option to choose at which rate the GEO samples and stores data
for later download to your PC. More frequent sampling will provide extreme detail
of your dive profiles with limited storage capacity.
