During spring 2023 Sukellusseura H2O ry is arranging the CMAS One Star Diver course under Sukeltajaliitto ry (Finnish Divers’ Federation) in English.

The goal of the CMAS One Star Diver -course is to teach basic scuba skills to new diver candidates.  After successfully completing the course the participants will be able to independently dive to the depth of 20m while breathing compressed air and observing the no-decompression limits.

The course is managed by Marcin Dobrucki (CMAS M3)


The course starts on February 1st, 2023 at 18:00.  A link to a teleconference will be sent to the participants beforehand.  Pool exercises will be held every other Wednesday between 19:00 and 22:30 at the Helsingin Urheilutalo swimming pool (Helsinginkatu 25, Helsinki).  Open water training will be arranged during one or multiple weekends around the second half of May – depending on the weather.  The open water training will either be from shore, or from the club’s boat Deko.

About the course

During the CMAS One Star Diver -course the candidate will receive training and skills to undertake scuba diving activities within the limits of the certification level.  The emphasis during the course is on skill performance and safety.

The course consists of a theory module taught through the Dyykki e-learning system, six confined water exercise sessions and four open water dives.  In-water exercises are carried in a swimming pool until skill mastery is achieved, and then in open water.

The CMAS Dry Suit course can be combined with the CMAS One Star Diver course to allow participants to undertake the dives using drysuits.  This is the preferred way due to prevailing water conditions in Finland.

Successful candidates will receive a CMAS One Star Diver certification card issued by the Finnish Divers’s Federation.  The card is internationally recognized as certifying divers to dive to 20m using compressed air and observing the no-decompression limits.
