The invention relates to the technical field of seabed detection, and concretely to a coil submarine cable detection device and a detection method thereof. The detection device comprises three groupsof induction coils for detecting the induced electromotive force of a submarine cable, the three groups of induction coils are mutually orthogonal, each group of induction coils is an annular coil, the detection device further comprises a data transmission module and an upper computer, and the three groups of induction coils, the data transmission module and the upper computer are in communicationconnection in sequence; the three groups of induction coils transmit the obtained corresponding induced electromotive force to the data transmission module, and the data transmission module processesthe induced electromotive force and transmits information of the maximum induced electromotive force to the upper computer. Further, the submarine cable detection method provided with a multi-coil array observation mode and im
