Find a hunter at sea (7)
I believe the answer is:
unearth
'find' is the definition.
(I know that unearth is a more specific form of locate)
'a hunter at sea' is the wordplay.
'at sea' indicates an anagram.
'a'+'hunter'='ahunter'
'ahunter' with letters rearranged gives 'UNEARTH'.
(Other definitions for unearth that I've seen before include "Expose" , "Disinter" , "Disclose" , "Disconnect terminal" , "Dig up for a hunter" .)
