Why learning how to dive with Enriched Air Nitrox (EAN) is an important speciality course to obtain.

Posted on: April 9,2016 By Gregg Aidikoff

As we should be learning when taking our first PADI Open Water course, we live in a nitrogen based atmosphere. Many people believe that the air that we breath is mainly oxygen but in reality every breath we take is 78% Nitrogen,21% Oxygen and 1% trace gases.At one atmosphere or 1 bar, this is normal for us and all animals on planet earth.When we scuba dive to 10 meters or 33 ft.,we are now at 2 atmospheres or 2 bar. We are breathing the same percentages of gasses, but the molecules have doubled, including the nitrogen molecules at 78%. At 3 atmospheres or 3 bar, the nitrogen molecules have now tripled on every breath.and, at 4 bar we are now breathing and consuming 4 times the nitrogen molecules on every breath. This is the essence of why we need to track our nitrogen consumption using tables and computers.When we learn how to dive with EAN, or Enriched Air Nitrox, we are reducing the amount of nitrogen we are breathing and consuming on each and every breath. So by using a mix of 30-36% Oxygen as an example, we can effectively dive longer at depth, and consume less Nitrogen per breath. Siam Aquatic Adventures teaches divers how to calculate and to analyze what is the appropriate mix of Oxygen to Nitrogen for a desired depth and dive time with a PADI EAN course.When many of us experience diving on a live aboard multi-day cruise, Siam Aquatic Adventures has found that not only is it more fun to have more bottom time on each dive, but also consuming less nitrogen on multiple dives over consecutive days is safer on your body. Some even say, that there is less fatigue while diving EAN on multiple days. Every diver should know and to understand about diving with EAN and Siam Aquatic Adventures Divers teaches a very thorough  and exciting course.

  • Gregg has been a great instructor - and he was very good at making me feel safe during the dives. When I started the diving lessons, I had my doubts and was a little freaked out, but with help from Gregg and his dive master (Andreas) - I was able to get beyond my limits in the coolest way. I am very blessed that I got my certification, and I will definitely keep diving! A Huge thank you Gregg !

  • My name is Jialei,from China. I got my PADI open water 17-18th, August with my amazing instructor Gregg Aidikoff!!! From the beginning of the training, Gregg was encouraging me and trying to get me over my biggest fear which is the water, but he never gave up and tried his best to make me trust him and allow him to take me to this amazing experience, even when I tried to give up a couple times he was there to take care of me, and finally I DID IT!!! I can’t believe I had done six dives in two days and I did so well without fear and with all the skills he taught me. I can say I’m super confidence now diving under water, his patience and experience under water just made me feel confident of myself and I can’t ever forget this amazing experience I shared with Gregg and my lovely girlfriend Harriet!!! I strongly suggest Gregg as a wonderful instructor with more than 14,000 dives open water and 40 years of experience, he made me feel comfortable and relaxed with his patience and confidence, I’m looking forward to diving with him again next time in Thailand!!!

  • Diving is a big challenge specially for the people like us from mountain. But diving with Gregg made this so simple and easy that one would just fall in love with the under water world. Thank you Gregg for making this possible.

  • October last year I completed my Deep Dive Specialty with Gregg. The training I received was very thorough, Gregg did a great job of highlighting the risks associated with the deeper dives. But at the same time Gregg was very easy going and was happy to answer all of my questions, no matter how silly. Will definitely dive with Gregg again in the future.

  • In May 2015 I took my Junior Open Water certificate, and I had Gregg as my instructor. Not only did he teach me how to dive, but also how to feel comfortable in the water.

    As soon as he started talking to me and telling me what to do, I knew that I would be in good hands for the rest of the trip. It was a really fun experience and I am so glad that I did it.

  • Last year I was lucky to be able to join a class trip (week without walls) with my daughter’s school (QSI Zhuhai).

    The trip included an Open Water class with Gregg. I joined the course together with all the students, and I had one of the best weeks of my life. Moreover, it was a very special and wonderful experience to share with my oldest daughter.

    Gregg is an fantastic instructor, and I was amazed how well he interacted and handled all the kids. Before going to Thailand several of the students were a bit anxious. However, Gregg and his co-instructors always made sure that everyone felt safe and secure. All students certified the Open Water course and they all did great.

    We look forward to many more courses and guided scuba diving tours with Gregg in the future.

  • I was there when Gregg fell in love with diving. It never failed to bring a smile to his face. I can see why it gives him such pleasure to reveal the magic to each student he invites to discover a whole new world.
