Hi Charlie,

I have been meaning to drop you a line regarding my recent experience with my first ANDI Course (CSU/SWD) and one of ANDI’s IDT, Todd Powell ITD#116. As I mentioned this was my first ANDI course and I went into it not expecting much since all of my previous diving course experience was limited to a certain large, "Club Med", diving agency. What I received during the CSU/SWD course was over and above anything I expected from the course and Todd. Todd’s enthusiasm, professionalism, non-biased and knowledgeable approach combined with the in-depth and excellent course content made the entire experience very rewarding.

While I was somewhat skeptical about the final SWD exam, thinking that it was going to be a "shut off your brain and fill in the correct answer from the text" it was anything but that. While many of the answers I felt comfortable with, having studied diligently, there were some that I really had to work at and think about. It was an excellent process and I think very differently about it now.

I am now an ANDI (and Todd Powell) convert. While the learning curve was somewhat steep, I honestly believe that the difference between my diving abilities and understanding prior to the course and after completing it are truly night and day. I am a much better, more informed and safer diver. This course has re-invigorated my desire to learn more about diving and diving related activities. Most divers seem to have their opinions about things (courses, equipment, configuration etc) and one thing I learned very quickly was to identify who I agreed with and respected. This is very important in both saving money and safety. I now have great respect for both Todd and ANDI.

The courses are really "courses for divers by divers ". Clearly ANDI’s standards are high and the diving community benefits from this.

I am currently participating in the TSD and have mapped out a number of other ANDI courses that I plan to complete in the near future. I am very much looking forward to each one.

David Gagnon.


Good Afternoon Ed,

This letter is to inform you of how I feel regarding one of your ANDI Instructors located in the Upper Peninsula of Michigan. His name is Rick Malone and he owns and operates UP Blue Water Divers out of Escanaba, Mi.
I think that ANDI is lucky to have a guy like Rick. I have always been interested in Diving and I have brothers and friends who are divers. This year, I decided to pursue this sport. I called several dive shops in the area (even up to 90 miles away). Some of them were professional dive shops and others were people doing it from their homes. Many of these shops were offering “cheaper” courses and/or quick courses, but I chose Rick because is the only one in my area that works with your agency. I asked him why he chose ANDI and he told me “because it is the best”. I now have to agree with Rick, it is the best. The training that we received from Rick was very thorough. We had over 40 hours of classes plus the pool and open water dives. The educational books that ANDI provided were excellent and full of useful information. As an extra benefit, It turns out that Rick is a great guy with lots of knowledge and experience, plus he has a great personality. Even though I am new to this sport, I can tell that ANDI is a great Agency that strives to be the best in the business by providing a quality educational program that allows a person to grow from Open Water Level 1 to any of the more advanced programs.
I am about to take Advanced Open Water Level 2 and SafeAir courses. I am very fortunate to have a great instructor and an awesome agency that will enable to me to develop into a professional in this sport.
Please let me know if there is anything I can do to promote your agency in my area.

ANDI's beginnings are a significant part of diving history.

Ed Betts and Dick Rutkowski joined together in 1988 to form American Nitrox Divers, Inc. (“ANDI”). The purpose was to standardize Instructor Training, Sport Diver Training, and refill station dispensing procedures for Enriched Air Nitrox diving.

Dick Rutkowski retired from the USA's National Oceanographic and Atmospheric Administration (NOAA) with 33 years of service in 1985. He served as Deputy Diving Coordinator and was the founder and director of the NOAA Diving/Hyperbaric Training and Diver Treatment Facility. He began teaching what he called "Nitrox Diving" for sport divers in 1987 under his IAND company. He is directly responsible for introducing this major advancement into the Sport Diving Industry.

After contractually agreeing to close IAND and work exclusively with ANDI, Dick sold IAND to an ANDI Instructor Trainer, Tom Mount. Although both companies continued, this act caused the founders to acrimoniously separate. Tom Mount continued with IAND under the trade name IANTD.

Ed Betts was the co-founder of Island Scuba Centers, Inc. (ANDI # 1), of Freeport, New York in 1968. The Betts Family closed Island Scuba Centers in 1997 after 29 years of service to the local diving community. At that time it was Long Island's oldest full-service scuba facility and had been one of the world's first “high tech” dive centers.

Ed has extensive experience as a practical engineer. He designs and installs specialty gas production and delivery systems and hyperbaric chambers. Ed is founder and Executive Director of ANDI International and has authored numerous published articles, instructor manuals and student text books.

It was through Ed's efforts and business acumen that so many of the standards and procedures that were developed by ANDI are now standard practices in the diving industry of today. In addition, Ed was the first individual to introduce SafeAir®, technical and rebreather diving to many parts of the world.

When the first production-run recreational rebreather was marketed by Dräger of Lubeck Germany, it was ANDI that produced the first training manual in English and German. Since then ANDI has closely followed the emerging rebreather market. As new production product has become available ANDI has produced manufacturer-approved training materials of the highest quality.

In 1991, ANDI trained and opened the first EAN facility outside of the USA. The concept and technology quickly spread as ANDI expanded throughout the world. ANDI’s concept of “optimal breathing gas technology”, at first shunned and criticized by the entire industry, has now become a standard part of diving practice.

As of October 2004, ANDI has training facilities in 68 countries and Regional Headquarters located in the United Kingdom, Israel, Sweden, Italy, Germany, Greece, Japan, Taiwan, Republic of Maldives, Latin America, Middle East and the home office in the United States of America. This growth throughout the world is due to ANDI's commitment to quality education, quality training materials and our dedication to dealer service.

ANDI's educational material is available in several languages in addition to English. These include Hebrew, Italian, German, Swedish, Dutch, French, Greek, Russian, Chinese Japanese, and Spanish with others in process.
