Malaysia will send more equipment to the southern Indian Ocean to join the search for Flight MH370 which went missing four months ago, a minister said Sunday. Defence Minister Hishammuddin Hussein said a Malaysian navy ship equipped with a multi-beam echo sounder - a device to map the ocean floor - would set sail on August 4 for the deep-sea search zone far off western Australia.
State energy firm Petronas, together with Deftech and Phoenix International, would deploy a towed device called a synthetic aperture sonar to scan the ocean floor, he said.
