Dive Leader Lessons DO6 and DO7 - Diving and Rescue Skills Review
In DUSAC, Dive Leader open water lessons DO6 and DO7 are combined in a single assessed dive. The dive is carried out from a RIB in approximately 15m of water using a shot line as a datum.

The DL rescue assessment is followed by a scenario-type question and answer session. Scenarios / questions are to be agreed by the examiners beforehand to ensure that the tests are run as fairly as possible. They may encompass all areas that a dive leader would be expected to know. Examiners are to be briefed fully by the training officer beforehand. A Nationally Qualified Instructor (NQI) must be present at all tests although assistant instructors may administer the test itself. The verdict of the NQI is final. The students will be given full reasons for failure and areas for improvement noted. If possible, the NQI should be present at all debriefs.
