Course content

Building on your previous knowledge, you will refine your theory and practical skills in the CMAS ** and achieve autonomous diving status. From now on, you will be able to plan and carry out dives with other diving partners who have at least the same level of training, take precautions for possible emergencies and take appropriate measures in the event of an emergency
.

Theoretical training

• Repetition/deepening of CMAS* / i.a.c. Open Water Diver
• Further knowledge of regulators, SCUBA with and without reserve circuit, instruments for diving including dive computers, tare systems, diving clothing, basics of operating compressors.
• Diving physics: gas laws in diving, in particular the laws of Henry and Guy-Lussac, light/optics, sound/acoustics, heat.
• Diving medicine: tissue types/compartments, anatomy of body and cranial cavities, basics of anatomy and physiology of the cardiovascular system, poisoning by respiratory gases, hyperbaric/negative pressure barotrauma, deep intoxication and decompression sickness, thermal damage and shock.

Practical training

• Dive planning
• Dive preparation
• Dive briefing
• Group management (of a partner)
• Orientation with and without a compass
• Diving in difficult conditions (e.g. night, current)
• Breathing techniques
• Determining the correct amount of lead
• Emergency procedures
• Behavior in the event of general problems, e.g. loss of partner

In addition, this CMAS** course includes further scuba diving-specific and freediving-specific exercises.

• 45 seconds time dive with constant change of position (about 10 meters).
• 30-meter distance diving without or 25 meters with neoprene jacket and pants.
• 7.5 meter deep diving in open water.
• 40 minutes of time snorkeling covering a distance of at least 1,000 meters, including ten minutes each in the breast position, side position, supine position and with only one fin.
• 100 meters snorkeling to a scuba diver lying at a depth of five meters, transporting the scuba diver to the water surface and 100 meters at the water surface, 50 meters each with different transport handles
• Jumping from a height of 0.5 meters into the water with complete SCUBA equipment in accordance with the rules

However, as an alternative to the CMAS**, you also have the option of completing the i.a.c. Advanced Open Water Diver course. This will not only familiarize you with navigation and diving at greater depths, but you can also complete another specialty of your choice.
