The U.S. Navy is to deploy two highly-specialized locating devices as it tries to find the black box of MH370 in the vast southern Indian Ocean.
A pair of TPL 25s were deployed aboard the Seahorse Standard, a Royal Australian Navy Rescue Support vessel that will tow them through the search area approximately 2,500 km southwest of Perth, Australia, according to Wired.
The 32kg Towed Pinger Locator 25 is a hydrodynamic microphone designed specifically to listen for the acoustic signal given out by the data and cockpit voice recorders carried aboard all aircraft. It can track the devices to depths of 6,100 m.
The Seahorse Standard will drag a TPL 25 through the search area at a speed of around 3 knots, while keeping the second onboard as backup. The device will be tethered to the ship using a 6,100 m long cable, while remaining about 305 m above the sea floor. The locator can detect a transponder signal between 3.5 and 50 kHz, which includes most commercial airliner data systems as they transmit at 37.5 kHz. It has a 3km detection radius. However, the underwater locator beacon of a black box only transmits a pulse every second for just 30 days.
