A good shot of late surveillance (7)

I believe the answer is:

deadeye

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

'a good shot' is the definition.
(thesaurus)

'late surveillance' is the wordplay.
'late' becomes 'dead' (similar in meaning).
'surveillance' becomes 'eye' (I am not sure about this - if you are sure you should believe this answer much more).
'dead'+'eye'='DEADEYE'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for deadeye that I've seen before include "One secures a shroud" , "Ace marksman" , "Unerring marksman" , "Expert marksman" , "top marksman" .)

I've seen this clue in the Sydney Morning Herald.
