    FILE- In this handout image provided by the U.S. Navy, The Bluefin 21, Artemis autonomous underwater vehicle (AUV) is hoisted back on board the Australian Defense Vessel Ocean Shield after successful buoyancy testing April 1, 2014 in the Indian Ocean. The Bluefin 21 sonar scanner has been used in the search for the wreckage of missing Malaysia Airlines Flight 370.

    Experts hunting for traces of missing Malaysia Airlines Flight MH370 lost a state-of-the-art sonar device for the second time in three months, NBC News reported.

    The "towfish,"an underwater sonar device dragged behind ships that scans the seabed for debris, was attached to an 1,800-pound weight to keep it floating from the surface when "the failure of a tow cable connector resulted in the loss," the Joint Agency Coordination Centre (JACC) said in statement Wednesday.

    A remote-controlled submersible was flown in from the United States to attempt to recover the yellow, torpedo-shaped unit from the seabed.
