After having earned your PSS Trimix 60M qualification you have gained sufficient experience in using normoxic trimixes and you now want to widen you horizons even further by extending the certification to 78 meters (225 feet) and you can do this thanks to the PSS "Trimix 80M" course.
This course is an intense but brief and synthetic experience because, in fact, you already received the basic training on the Trimix 60M course. All you have to do now is get used to the added difficulty of managing two decompression cylinders on the dive.
On successfully completing this course you will be certified to dive autonomously, within the established limits for technical diving and with the following restrictions: maximum depth 78 meters (255 feet); use of oxygen-nitrogen bimixes and oxygen-helium-nitrogen trimixes, with oxygen percentages greater than 16%; use of two decompression mixes different from the bottom mix.
