ANDI International enriched air and technical training agency.

  ANDI International (ANDI) is one of the world's fastest growing diver training agencies. ANDI began by specializing in training programs for Enriched Air Nitrox ( SafeAir ) diving. As a natural evolution from SafeAir®, ANDI developed training programs for what has now become known as Technical diving and Closed Circuit Rebreather systems. To meet the demands of our international network of training facilities, in 1999 ANDI introduced a unique methodology for training entry-level divers with the ANDI Open Water Sport Diver program.

Since our origin in 1988, ANDI has expanded throughout the world with Regional Headquarters located in the United Kingdom, Israel, Australia, Sweden, Italy, Germany, The Netherlands, Greece, Japan, Taiwan, Republic of Korea, Republic of Maldives, Republic of Philippines, Latin America, Middle East and the home office in the United States of America. To meet the needs of these regional markets ANDI developed educational material in many languages in addition to English.

ANDI has developed a multifaceted training system with comprehensive programs. These include Openwater Sport Diver, Dive Medic, SafeAir® User courses, Technical and Exploration programs, Rebreather training for SCR and CCR systems, specialty-focused training and a full offering of technician and instructor programs. ANDI’s growth throughout the world is due to ANDI's commitment to quality education, quality training materials, the highest operational standards and a dedication to customer service.

  Many divers have asked how EnviroDive ended up writing the PADI/DSAT Gas Blenders Manual.

Years before PADI began offering gas blender training through DSAT
1 they recognized the need for this type of training.

As you may remember, PADI was initially very cautious about entering the Enriched Air Nitrox field. Starting with a basic nitrox course they found that the missing ingredient was not so much "how to dive the gas mix" but "how to get the gas mix".

Back in 1997, EnviroDive was approached by PADI to see if we would offer our gas-blending program at DEMA
2 exclusively for PADI dive shops and instructors. The results were overwhelming. The initial success of these courses resulted in them being offered at subsequent dive shows.

Year after year the attendance increased to the point where we were offering a gas blenders course before DEMA as well as a gas blender instructors course following the trade show. To accommodate the overflow students we often had to deliver evening courses during DEMA.

From a business point of view our relationship with PADI could not have been better. We had done our homework and developed what many considered to be the best gas blender training available but as a fledgling training agency we lacked the credibility of the established, big name agencies.

By aligning ourselves with PADI we piggybacked on their reputation as well as enjoyed their advertising and support. What PADI received from us was a quality course that met their standards and an opportunity to be able to offer gas blender training to their dive shop operators and instructors immediately without having to wait for the development of their own course.

With the continued success of the EnviroDive gas blender program, PADI/DSAT decided that it was time for them to have their own gas blender course. Instead of re-inventing the wheel, it was decided to contract EnviroDive to develop the Gas Blender program. I would like to say that it went without a hitch, but it didn't. Thankfully, even with the many disagreements resulting in a few compromises (by both sides), the end result is the DSAT Gas Blender Manual.

On behalf of EnviroDive, I sincerely hope that the PADI/DSAT Gas Blender program fulfills your gas mixing needs.
