PADI Enriched Air Diver Specialty

from €167

Course Description

The duration of our adventure under the water is controlled by several factors, but dive time (specifically ‘no stop limits’) and the supply of gas we carry with us are the two most important. Increasing our gas supply is easy, just increase the volume of gas you carry (see the PADI Tec Basics course), but increasing our ´no stop time´ requires the use of a breathing gas that has reduced nitrogen and increased oxygen. The PADI Enriched Air Diver specialty provides you with the knowledge and training to understand how and when to use oxygen enriched air (EANx) with mixes from 22-40% oxygen.

We offer two different styles of this course; ‘Computer’ or ‘RDP Assisted (tables)’, so which one is right for you? The majority of today’s recreational diving are done with dive computers, so the ‘Computer’ specialty is the preferred choice, extending the style of diving you already do with air (21% O2) to now include up to 40% oxygen. If you’re considering to progress on to technical diving then the ‘RDP Assisted (tables)’ specialty is a more suitable course, introducing concepts that you’ll later find in your technical diver training.

Both courses take just half a day to complete and are offered as ‘dry’, which means that no actual diving is required. We can offer diving with Enriched Air Nitrox, please just let us know when you book the course so we can arrange this.

Course Content

The PADI Enriched Air Nitrox Diver Specialty includes everything you´ll need. We´ll supply you with –

• Use of oxygen analyser, EANx dive computer and EANx filled diving cylinders for analysing.
• Choice of the ‘Computer’ or ‘RDP Assisted (tables)’ PADI Enriched Air Diver Specialty manual
• RDP Assisted (tables) manual comes with 32%/36% RDP & EAD (Equivalent Air Depth) tables
•  Certification upon successful completion

And remember that on all of our courses there will never be more than four students per course!

You can book this course from €167 or alternatively enjoy a fully inclusive diving holiday from just €247 (2 people sharing)

Enriched Air Diver Specialty

The PADI Enriched Air Diver specialty comes with a comprehensive and informative manual, available in both ‘Computer’ and ´RDP Assisted (tables)’ format. Within each of the formats you’ll get to look at -

Enriched Air Diver Specialty• Advantages and Disadvantages of Diving with Enriched Air and Enriched Air Computers
• Equipment for Enriched Air Diving
• Oxygen Exposure
• Oxygen Analysis and Obtaining Enriched Air Fills
• Guidelines for Diving with Enriched Air Dive Computers
• Diving emergencies and enriched air

Included within the manual are two Knowledge Development sections that you´ll need to complete, and are designed to help you better understand and retain the information.

Enriched Air Nitrox Exam – To successfully complete this specialty there is a multiple choice style exam, with a pass rate of 75%.

With the knowledge developments and exam completed we will conduct two practical sessions and two pre-dive simulations. Within each section we will look at the following -

Practical Application One & Pre-dive Simulation One

Enriched Air Diver SpecialtyOur first chance to analyse an EANx cylinder using an oxygen analyser. We’ll look at how to operate the analyser, take a reading, record the details and apply this to our diving. We’ll also look at how to put this information into an ‘EANx’ dive computer, and plan a dive.

For both versions of the course we will -

• Demonstrate how to use an oxygen analyser to determine the oxygen content in an enriched air blend
• Demonstrate how to verify cylinder content data and sign the fill log
• Plan a dive within the no stop limits, maximum depth and oxygen exposure limits established by the instructor

Practical Application Two & Pre-dive Simulation Two

Enriched Air Diver SpecialtySimilar to before, but this time we’ll look at the procedures for obtaining our EANx fill from an approved fill station, and again using this information to plan an EANx dive.

For both versions of the course we will –

• Demonstrate the procedures for obtaining an enriched air fill and/or renting an enriched air cylinder from an enriched air fill station
• Plan a dive within the no stop limits, maximum depth and oxygen exposure limits established by the instructor (computer version)

Or

• Plan an enriched air dive using the RDP, DSAT Equivalent Air Depth and Oxygen Exposure Tables and Enriched Air RDPs (RDP Assisted (tables))

What other courses can you link in, and achieve greater enjoyment and safety under the water? The obvious benefits of using a breathing gas with a higher oxygen content is to extend your ‘no stop limits’, but it is possible to further increase dive time by selecting a dive profile with different levels; replacing a dive that follows an ‘ad hoc’ profile with one that has pre-defined depths that you stay within. The PADI Multilevel and Computer Diver Specialty course looks at how nitrogen loading into different theoretical tissue compartments in the body can affect your ‘no stop limits’, and introduces the concept of progressing to shallower depths during the dive to extend dive time. When used with EANx it´s possible to undertake a deeper dive and still have a long runtime.
