Find a wader moving about over a large area (3,3,4)

Ross

I believe the answer is:

far and wide

I'm a little stuck... Click here to teach me more about this clue!

'over a large area' is the definition.
I can't tell whether this defines the answer.

'find a wader moving' is the wordplay.
'moving' is an anagram indicator.
'find'+'a'+'wader'='findawader'
'findawader' is an anagram of 'FAR AND WIDE'.

'about' is the link.

Can you help me to learn more?

(Other definitions for far and wide that I've seen before include "Everywhere" , "Extensive" .)
