In ECHO SOUNDING, false indications occasio­nal­ly appearing on the DIAL or FATHOGRAM of an ECHO SOUNDER. They may be caused by the motion of the vessel through the water, by acoustic or electric NOISES in the ship, or by electric NOISES in the echo sounding equipment. Strays may be mistaken for the true echo or may be of such a nature as to prevent the identificati­on of the true echo.
