Was your Solo Diver "course" a whole two days?Situational awareness, was a big part of my Solo course.
Rescue diver is considerably longer and includes EFR and a whole load of other things. At least mine was and it was taught in the conditions I dive in — cold, poor vis, sea. The search and recover/rescue was one of many highlights.
My solo "course" really didn’t teach me anything I didn’t already know. Not me being clever, just me being prepared and fully dived up taking the Solo "course" after normoxic trimix.
