Mixed Gas Training Frequently Asked Questions

Where can you get mixed gas training?

A number of training organizations offer different types and levels of mixed gas training. Training organizations such as, IANTD, GUE, NAUI, and TDI all offer mixed gas training. Finding a dive shop in your area with technical instructors may be difficult. Typically, only dive shops that categorize themselves as “technical” shops offer this type of training. You may have to travel out of your area to find a dive shop or instructor.

How much does mixed gas training cost?

Trimix courses range from $500 to $800+. Gas mixing technician or blender courses range from $150 to $200. Trimix courses assume that you have all of your gear, which means gear is not included in the course price. Check with your training agency and instructor for detailed costs and breakdowns.

How long does the training take to complete?

Trimix courses can take up to five days to complete. Many hours of classroom work as well as four to six dives must be completed. Each training organization has different requirements and time-to-complete can vary. Check with your training agency and instructor for a detailed time schedule for the class you are interested in taking.

Gas blender courses typically last two nights or maybe one full day. Again, each training organization has different requirements to complete the course. Check with your training agency and instructor for a detailed time schedule for the class you are interested in taking.

How long does the certification last?

Certification in mixed gas courses never expires. There is no yearly requirements or payments to keep your certification current. If you haven’t used mixed gas in a year or more, it’s recommended that you go through refresher training.

What do you learn in a mixed gas training course?

Entry level or beginning trimix courses provide the training required to competently and safely utilize breathing gasses containing helium for dives that require staged decompression, utilizing nitrox and/or oxygen mixtures during decompression to a maximum depth of 200 or 225 fsw (60 or 68 msw).

Advanced level courses provide the training required to competently and safely utilize breathing gasses containing helium for dives that require staged decompression, utilizing nitrox and/or oxygen mixtures during decompression to a maximum depth of 300 fsw (91 msw).

Mixing technician and gas blender courses provide you with the skills, procedures, and knowledge needed to safely handle high-pressure gases and prepare EAN and helium based gas mixes for use by divers. You learn how to prepare and blend high quality gas mixes. In addition, you may also learn the skills necessary to clean, test, and document the testing of equipment used with high levels of oxygen.
