BSAC Advanced Mixed Gas Diver
The Advanced Mixed Gas Diver course allows the diver to pick and choose their preferred gas mixture for the depth of the dive and allows the diver to expand their depth experience to 80 meters. The course is open to Sports Divers or equivalent who hold the Explorer Mixed Gas diver certification and have 100 or more logged dives.
The Advanced Mixed Gas diver consists of the following elements:
Again the theory builds on the knowledge gained from the sports and explorer mixed gas diver courses. The course takes the students much deeper into physiology and decompression theory as well as going over advanced dive planning procedures, equipment and decompression systems. The Theory lessons covered are as follows:
Once the students have completed the theory lessons they will be given the Advanced Mixed Gas Diver Exam with a required pass mark of 80%
The dry practical session is time for the students to get some practical experience of any new equipment they will be using during the dives and to make any necessary adjustments to their equipment rigs.
Confined Water Session
The confined water session is a chance for the diver to practice old skills as well as introduce several new skills. The diver as always will be assessed on his/her buoyancy skills as well as practicing skills such as regulator switching, mask switching and out of gas procedures. The duration of the confined water session should be no less than 90 minutes and additional sessions may be added if required.
Open Water Dive
Once again the main emphasis on the open water dives is to maintain correct depth, run time and gas management. However on dives 1 to 3 the diver will also be expected to perform skills such as helicopter turns, shutdown drills and DSMB deployment. Dives 1 and 2 are done down to a max depth of 35m, this allows the student time to get comfortable with equipment etc and gives the instructor time to assess the students before moving onto deeper dives. Dives 3 and 4 are depth progression dives to 55 and 65m with the emphasis being on run time management and gas management. The final dive is the final assessment dive to 75/80m, This dive will be thoroughly planned and briefed by the students and once everyone is happy and comfortable with the plan the students will lead the dive with the instructor assessing their progress throughout the dive.
Upon completion of the course you will be presented with the BSAC Advanced Mixed Gas Diver Certificate.
