A level finder drops credit (8)
I believe the answer is:
dipstick
'a level finder' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'drops credit' is the wordplay.
'drops' becomes 'dips' (I've seen this in another clue).
'credit' becomes 'tick' (I've seen this in other clues).
'dips'+'tick'='DIPSTICK'
Can you help me to learn more?
(Other definitions for dipstick that I've seen before include "Engine oil measuring device" , "Fluid measuring rod" , "Turkey" , "Oil gauge" , "Graduated rod for measuring oil levels" .)
