The course, I feel because of the hours it took, should have been over 7 days instead of 5. When I did my initial course in 1999 only 1.5 days were spent on the locator and signing lighting & guarding. On that course we also covered units 15 & 16. I feel that if it is now considered necessary to spend 2.5 days on locator & slg training, I would suggest that it is either carried out as a separate course or as I said made into a 7 day course.
