Pleasure Diving Computers

Presentation

Dive computers are in widespread use today and offerings from multiple manufacturers.
In recent years, new functions have appeared on the market, ranging from nitrox to multi-gas management, including electronic compasses, integrated air management, the concept of deep stops, optional stops, freediving mode, etc.
On the display side, the latest OLED technology has appeared alongside traditional LCD screens, now posing differently the question of screen ergonomics and access to different functions.
It is even possible to see information on desaturation in your mask and to use your smartphone as a dive computer.
On the interface side, Bluetooth technology has been integrated, making it possible to export data not only to his desktop computer, already available for many years via a physical connection, but also to tablets and, in general, to any mobile support.
As for the desaturation models, they now all integrate the Haldanian approach (dissolved nitrogen) and the microbubble approach, for even safer decompression.
In short, you have understood it, the world of dive computers is in full swing and it was necessary to take stock of the issue, to have an overview to better understand the possibilities offered, the choices offered and the safety issues of desaturation.
This is the subject of this Plongée Plaisir memento which is aimed both at divers, whether supervised or autonomous, and at supervisors, guides, initiators and instructors.
Divers will find the answers to their questions there:
- How does a dive computer work?
- What are the selection criteria?
- What are the limits of use?
- What are the main functions available?
- What is a desaturation model?
- etc.
The supervisors will be able to draw from it material for their courses on desaturation procedures.
With this in mind, each page of the memento is captioned:
PE: means that the page concerns supervised divers, who must know how to read their instrument, understand the key concepts and know the possibilities offered.
PA: means that the page concerns scuba divers. In general, they must be aware of all the possibilities offered by their instrument and, in particular, be aware of the configuration possibilities having an impact on the safety of the desaturation.
EP: means that the page is intended for supervisors (guides, initiators, instructors), whose knowledge in the matter must be broader than that of autonomous divers and go beyond their only instrument, in order to be able to advise divers who 'they supervise, help them in handling their computer and guide them in their choices.
