Explain how to look through a scope

[fabsroman]

Simple way to explain it is that she needs to move her head forward or backward until she does not see any black around the outside edges of the scope circle. When she looks through the scope, there should be no black at all in the field of view.

That is how it was explained to me and it has worked. However, I have busted my head once or twice from putting my head too close to the scope since scopes have 2 relief positions. Tell her to pick the one furthest back from the scope. It will be better for her in the long run.
