Sub detector (5)

Ross

I believe the answer is:

sonar

'sub detector' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for sonar that I've seen before include "Underwater echo sounder" , "Underwater detection system" , "Echo-sounding equipment" , "Detection system at sea" , "Locating device" .)

I've seen this clue in the Universal, The Wall Street Journal, the USA Today, the Penny Press and the King Feature Syndicate.
