Locating the black box is crucial to know how Flight MH370 mysteriously ended in the Southern Indian Ocean. Even if the debris field is located, finding the black box before it runs out of battery life is a tough ask. The black box has a 30 day battery life, through which it will emit sound pulses to reveal its location. The ping's will stop on April 7. If happened, the search efforts would require more time and assets, added to the already herculean task.
US Navy has deployed its Towed Pinger Locator to locate black box ping's.
