This course is a continuing education course for certified divers. The importance of dive planning is stressed, as well as types of diving. There is an open discussion of advanced diving practices and procedures. Training dives will take place at Lake Isis and either Paradise Springs or Key Largo under the direct supervision of the dive instructor. These dives will concentrate on air consumption calculation, underwater navigation, buoyancy control, emergency procedures and self-rescues. Students will perform an open water safety stop and simulate decompression. Other dives include a deep dive and a low light or night dive. This private class is available for those whose schedule demands a more flexible time frame and can be completed during the day or on the weekend.
