Good question. I think it would be great to video the line/full cast, rod and student
as documentation of the whole ball of wax
but that requires a very wide angle --
focusing on just the student and lower rod often gives sufficient information
when you are working 1 on 1 with a student. The student can usually see what's happening with the line after
you tell them what to look for, for example
an overly wide loop. So we
can focus on movements of the hand, arm, shoulder, and lower end of the rod
needed to make a narrower loop.
Lots of students can't visualize how they are moving the rod and a video really
But to come clean,
in the short term, I am working on my own casting and I want to see what
the heck I am doing with shoulder, elbow and hand so
I can be more efficient in my casting. It can be surprising what you
see when you video yourself...at least it was for me.
