PERSONAL

There Have Been Many Bad Dive Computers On The Market That Have Come And Gone (Unfortunately We Got Treated Bad And Wasted Money On A OCEANIC Computer!).  A Generic Model Dive Computer Is Something Like Diving With A Digital Dive Table; So Why Bother, Save Your Money And Dive With A Dive Table!  The Market Is Filled With Bad And Very Dangerous "Used" And "New" Dive Computers.  Many Can Cause A Sense Of False Security; Causing The Diver To Not Pay Attention To The Risks And Their Personal Dive Health Profile!

Suunto's Advanced Approach To Personal Instrumentation Is Well Know Around The World, And They Bring Advanced Thinking To Diving.  There Are Personal Factors That Can Affect Your Personal Susceptibility To DCI, Which You Can Predict In Advance, And Input Into The Decompression Model Of The D4.  Such Factors Vary Between Divers And Also For The Same Diver From One Day To The Next!

A Easy 'Three-Step Personal Adjustment' Is Made Available.  For Very Experienced Divers, A Two-Step Adjustment For RGBM Effect On Repetitive Dives Is Available.

Personal Factors Which Tend To Increase The Possibility Of DCI Include, But Are Not Limited To:

? COLD Exposure - water temperature less than 20 ?C/68 ?F
? Below Average Physical Fitness Level
? Fatigue
? Dehydration
? Previous History Of DCI
? Stress
? Obesity

DIVING EASY

Welcome To The World Of Casanova's SUUNTO Diving Instruments.  The Suunto D4 From Finland, Was Designed To Help You Get The Most From YOUR Diving!  Powerful Computing Intelligence Combined With Advanced Medical Research, Simplifies Your Diving Experience; Enabling Personally Computed Information On Depth, Time, Decompression Status, Altitude, No-Fly Time, Which Can Extend Dive Times, And Fit More Dives In A Day, Or Holiday Travel.

RGBM/DEEP STOP ALGORITHM

Suunto?s Reduced Gradient Bubble Model (RGBM), utilized in the Suunto D4, predicts both dissolved and free gas in the blood and tissues of divers.  It is a significant advance on the classic Haldane models, which do not predict free gas. The advantage of Suunto RGBM is additional safety through its ability to adapt to a variety of situations and personal dive profiles.

In order to optimize the response to different increased risk situations, an additional category of stop, referred to as a Mandatory Safety Stop, has been introduced.  The combination of stop types depends on the user settings and the specific dive situation.

4 PRACTICAL BUTTONS | EASY MENUS

'MODE', 'SELECT', 'DOWN', 'UP' Printed On The Bezel Next To The Associated Button.

Modes: Three Main Operating Modes; 'TIME', 'DIVE', 'MEMORY'

Mode Select: Press 'MODE' Button

Mode Functions Menu: Scroll Through Menu Pressing 'UP' Of 'DOWN' Button.

Function/Setting Selection: Press 'UP' Or 'DOWN' Button To Increase Or Decrease A Setting's Value; And To Select Alternative On-Screen Data Display When Available.

DIVE MODE AUTOMATIC

The system activates automatically when submerged deeper than 0.5 m/1.5 ft..  However, it is necessary to activate the DIVE mode BEFORE diving to check the altitude and personal adjustment settings, battery condition, oxygen settings etc.

Graphic Surface-Time Indicators

	Attention! Extend Your Surface Time
	Violated Decompression Ceiling
	Do Not Fly Flying or traveling to a higher altitude should be avoided at any time when the computer is counting down the personal no-fly time.  The no-fly time is always at least 12 hours, or equivalent to "desaturation" time, if longer than 12 hours.  Suunto recommends that flying (Higher Altitude) is avoided until all the DAN and UHMS guidelines, as well as the personal dive computer?s no-fly conditions, are satisfied.

Repetitive Dive Planning

A Onboard Pre-Dive Planner Enables Reviewing No-Decompression Limits Available To Dive; Based On Residual Nitrogen Loading From The Previous Dive.

Lifestyle Time Piece | Fiji Time

Decompression Dives

When The 'NO DEC TIME' Display Is ZERO '0', YOUR Dive Becomes A 'DECOMPRESSION Dive'; And YOU MUST Perform One Or More Decompression Stops To Return To The Surface.

'ASC TIME' And 'CEILING' Will Appear.  An Up Arrow Will Indicate To Start An Ascent.

If The No-Decompression Limits On A Dive Is Exceeded, The D4 Will Provide The Decompression Information Required For Ascent.  After This, The Instrument Will Continue To Provide Subsequent Interval And Repetitive Dive Information.  The Ascent Time (ASC TIME) Is The Minimum Amount Of Time Needed To Reach The Surface In A Decompression Dive.

Ceiling, Ceiling Zone, Floor And Decompression Range

Continuous No-Stop Decompression

Advanced Computations Enables Decompress Within A Range Of Depths, Rather Than Stopping At Fixed Depths.

Extra Safe

When Ascent Rate Exceeds 10 m/33 ft Per Minute Continuously For More Than 5-Seconds, The Microbubble Build-Up Is Predicted To Be More Than Is Allowed For In The Decompression Model.  The Suunto RGBM Calculation Model Responds To This By Adding A 'Mandatory Safety Stop' To The Dive.  The Time Of This 'Mandatory Safety Stop' Depends On The Severity Of The Ascent Rate Excess.

Safety Stops
Safety Stops are widely considered good diving practice for recreational diving, and are an integral part of most dive tables.  Reasons For Performing A Safety Stop Include: Reducing Sub-Clinical DCI, Microbubble Reduction, Ascent Control, Orientation, Diver Check And Clearance Check Before Surfacing.

Real Time Bookmarks

PRESS 'SELECT' Button ---- Instantly Record 'Depth', 'Time' And 'Water Temperature' In An Instant, During The Dive, To Active Dive-Profile Log.  Each Of These Entries Is Referred To As A "Bookmark".  'Bookmarks' Are Displayed When Scrolling Through The Dive-Profile Memory On The D4 Display.  'Bookmarks' Are Downloaded And Shown As Annotations In The 'Suunto Dive Manager' PC-Software Tool Suit.
