Traditional speed measuring devices have been largely replaced by the acoustic Doppler log. This can make measurements of velocity relative to the sea bed, but only in modest operating depths. Greater depths can be attained using the correlation log. This is not yet an established technique, and the principles of the design parameters for a satisfactory system are discussed.
