EANx Gas Blender in worldwide: 16 dive centres on TecDiveTools, with agencies, courses taught and a summary of what students say. 10 publish course prices.
TecDiveTools lists 16 dive centres teaching EANx Gas Blender worldwide. 10 of them publish course prices, in the currency the shop advertises and with the date each was checked — not converted, and not estimated.
Listings are ordered by how much evidence exists about their technical diving, not by a star rating, with any paid Featured listing shown first and marked as such (how rankings work). 11 of these 16 carry reviews we have read and classified as being about technical or overhead training. The count excludes recreational certifications by name, so a busy resort does not outrank a one-instructor cave operation on the volume of its reef trips. Separately, 9 have at least one instructor whose reviews we have read and summarised — a dive centre carries no synthesis of its own. How we read and count reviews.

About the course
This classroom and hands-on certification qualifies individuals to mix, analyze, and blend enriched nitrox (EANx) gases for safe recreational and technical diving applications. You'll master oxygen/nitrogen partial-pressure calculations, oxygen compatibility and equipment cleaning, gas analysis techniques, record-keeping, and safety protocols for professional gas blending operations. EANx Gas Blender is valuable for dive center staff, expedition planners, and independent gas blenders seeking to provide high-quality mixed gases for diving operations.
Divers must demonstrate competency in oxygen handling safety, gas mixing calculations, equipment compatibility verification, and gas analysis accuracy to recreational and technical diving standards.
16 dive centres on TecDiveTools teach IANTD EANx Gas Blender worldwide: Thailand (6), United States (5), Indonesia (3) and Mexico (2). Each is listed above.
Every centre in the TecDiveTools directory that publishes a price for IANTD EANx Gas Blender worldwide charges by the day rather than for the whole course. Prices differ mainly in what they include, so compare the inclusions before comparing the numbers. Prices were last checked in September 2026.
1 day, based on the durations 1 centre publishes for it worldwide. The time depends on the centre's schedule, weather, and how quickly the required skills are demonstrated — agencies set a minimum number of dives, not a fixed number of days.
At the same tier in TecDiveTools' cross-agency comparison, dive centres worldwide also teach TDI Nitrox Gas Blending (106), PADI TecRec Tec Gas Blender (3) and RAID Gas Blender (1). They are comparable rather than interchangeable — each agency sets its own standards and card, so check which one your next course accepts.
