Can it tell you just where your golf ball has landed? (3,8)
I believe the answer is:
lie detector
This clue could be a double definition.
'can' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'it tell you just where your golf ball has landed?' is the second definition.
The definition suggests a singular noun which matches the answer.
Can you help me to learn more?
(Other definitions for lie detector that I've seen before include "Machine for establishing truth" , "Police polygraph" , "Device helping find truth" , "help to tell a story" , "Truth-finding machine" .)
