During the course, the student will be taught the use of oxygen enriched air as a breathing gas on no-decompression dives.

The course consists of one confined water training session and four open water course dives, two of which will be made to a depth of about 30 metres. Skills emphasized during the course are dive planning, buoyancy control, propulsion techniques, decompression cylinder handling, spool and surface marker operation and working as a team member. Breathing gases during the courses will be nitrox (EAN21-EAN36) for bottom gas and decompression (EAN50 or O2, max PPO2 1.5). After certification, the student has the skills to safely dive to 40 metres using one decompression gas.

The course follows the Advanced Nitrox course outline with the exception of the bottom gas, which on at least two of the open water training dives will contain helium. After certification, the student has the skills to safely dive to 45 metres using one decompression gas.

During the cavern diver course, all dives are made in an overhead environment with daylight in direct sight. Skills emphasized during the course are dive planning, buoyancy control, propulsion techniques and reel handling. The course contains a confined water training session and four cavern training dives. A common site for the cavern course is the Kaatiala Quarry in Kuortane.

This is the first real cave diving course, where most of the essential cave diving skills are trained. The dives are limited to 1/6 gas rule. There will also not be any decompression diving. All dives are done on the main line, no jumps or restrictions are negotiated. The course consists of 4 – 6 dives.

The course is intended for experienced tech divers wanting to dive safely in mines. Routine diving twinsets and a good buoyancy control are essential. The essential cave diving techniques are trained. Dives are done partly on the mainline, but jumps and short restrictions such as doorways are negotiated. The course consists of 6 – 8 dives.

The course is intended for trained and experienced cave divers, who want to extend their dives with the use of a dpv. The course consists of at least four dives, on which skills such as correct riding posture and technique as well as towing and gas sharing emergencies are trained. In addition to these, dpv construction, maintenance and handling are parts of the course.

The course is intended for trained and experienced cave divers, who want to extend their dives with the use multiple bottom gas stage cylinders. The course consists of at least four dives, on which handling and management of at least two stages is trained.

The course consists of at least four dives, on which skills such as correct riding posture and technique as well as towing and gas sharing emergencies are trained. In addition to these, dpv construction, maintenance and handling are parts of the course.
