The U.S. Navy has unveiled a groundbreaking advancement in the detection of lost underwater devices, ships and aircrafts, with the underwater device-tracking microphone called the Towed Pinger Locator 25.

The 70-pound tow fish is a hydrodynamic microphone that has been constructed and designed specifically for detecting acoustic underwater signals from data and cockpit voice recorders that are carried aboard all military and commercial aircrafts.

Reaching depths of 20,000 feet, this underwater microphone is set out to help find the missing Malaysian airline that disappeared without signal into the depths of the Indian Ocean. This could be exactly what was missing in the ongoing search of the missing flight that has torn many families apart.

This advancement is a prudent effort to detect debris and move closer to the specified search area, furthermore advancing the development of finding missing valuables within the depths of the ocean.
