A New Way to Look At Dive Planning


Plan your Dive and Dive your Plan is one of the thing that our instructor told us, over and over, when we first learned how to scuba dive.

We believe in this, and we are taking dive planning to the extreme; making it easier and more interesting for you.


You know already that with eDiving, our scuba diving simulator, you can virtually dive a real place to get an idea of the "lay of the land" (in this case the submerged one).


Now, with the introduction of divePAL, you can use the dive profiles generated by eDiving to Plan your real dives.

Imagine this; you are planning a 2 tanks dive trip on the USCGC Duane and Bibb in Florida and you would like to know what you are going to see and how your multi-levels dive profile will look like to reach your dive objectives. How do you plan those dives?

Simple, dive into the eDiving simulator and go explore both wrecks, then log each dive making sure to save - in the cloud - the dive profiles. Then fire up divePAL and load those profiles - or you can even search for similar virtual dives performed by other members of the eDiving community - and analyze them.
With the free Basic version of divePAL you can review one dive at time, and with the Full and Nitrox versions you can create series of 3 and 5 dives respectively.


By the way, the dive profiles saved by eDving are already in 3D .... and soon divePAL will show you also the dive paths in addition to the dive profiles.

Cool eh?

Fine Tuning a Decompression Algorithm
Part 1 of 3
I have been asked several time what kind of decompression algorithm is DiveNav using in its eDiving and divePAL simulators and my answer invariably was ...... "Buhlmann"  ;)
But I realized that probably you wanted a more specific answer, and maybe even a comparison of our algorithm against the ones used in real dive computers.

Existing Data
We did some research and found a very interesting article published by ScubaLab: Digging Deep on 2009's New Dive Computers. This article is based on a report generated by our friend Karl Huggins and his staff from the USC Catalina Hyperbaric Chamber.
This article describes the results of a head-to-head comparison among several dive computers during a series of 4 dives performed at the Chamber.

Our Tests
To test our own decompression algorithm we entered into divePAL the series of 4 dives (dive profiles and surface intervals) described in the original report. We used the recently released divePAL Nitrox because it allows to Plan and Analyze series of up to 5 dives.
Here below the profiles for the 4 dives:divenav community 15000 members

From the winner of the Suunto D6 dive computer
Congratulations to Ray Chesney from London, Kentucky for winning a Suunto D6 dive computer!

This is what Ray had to say about the D6 and its related online class:

"I really enjoyed the online dive computer class for the Suunto D6 it covers all the functions of use in an easy to learn way. The D6 is very similar to the old discontinued Vyper 2 computer that I have in function and use. The online classes are a great tool as a SCUBA instructor its not always easy to teach student about all the different computers so having them take the online classes make my job easier."
