We could easily build a pinger detector so we would run out and detect pingers. youd have to download the data but it would be geo referenced so youd know where the ping came from. these tools you can launch from multiple boats. >> david malco reported that the conditions are murky, the sea is churning and royaling and that its a mess under there. does that matter? >> it does for visual but for pinger and side scan sonar, it does not matter. you can use these tools in murky water. >> miles, the ...

Location. were told that even though these waves are fairly high and you can see its choppier than it was, this is considered fairly good weather. this is better than it has been for some days. >> the crews looks for debris and bodies. one of them spots something. hes unsure what exactly. the captain calls it in a larger ship in the area will investigate. this search and is rescue boat has a specific mission to deliver a pinger locate tore help with the vital search for the so called black boxes...

Investigate. this search and rescue boat has a spec mission, to deliver a pinger locateer to help with the vital search for the so-called black boxes. but the captain is nervous about the weather. "i feel a heavy burden," he says." i have a responsibility to keep those on board safe but its so important to help find bodies and debris." larger ships compose these conditions he says "this is not a large ship." at the search zone the contact boat is in sight. time to hand over the equipment. easier...

>> reporter: the search for airasia flight 8501 narrowing. the hunt on for a tiny signal in a turbulent sea. minute pings from a device attached to the flight data recorder. >> a pinger has a specific pulse. it comes at a specific interval and it has specific frequency. >> correct. >> but its still hard to find? >> yes. it is. >> reporter: forensic audio expert paul ginsburg simulated what a pinger would sound like undistorted and without by this competing sounds. [ pinging ] but, says ginsburg ...

Teams that they find the tail of the plane, the black boxes, will that be the end of the search? >> oh no i mean they have to map the whole area and for forensic study just as everything they can possibly look around the area of the crash to put the pieces together. now, that being said there are tools that can be brought into play for these divers in low visibility. this sonar -- hand held sonar and pinger locators that the divers can take in the water and bring down we use them all the time on...

Former ntsb managing officer, good to see you again. we have got a black box here. its orange. thats the way they are so they can be spotted in debris. but help us understand how they work and how this is fairly typical to the black box ses. >> it is orange. easy to identify. easy to find visually. you have got a pinger here on the one end. that will be activated as it hits the water you will have information coming from the actual black box telling you where you can locate that. most can often ...

It is going to have data from what the cockpit is saying what the people in the cockpit are saying to one another and to the ground. >> generally they have to be on top of these boxes in order to hear the pingers. the weather has been a big problem. but as we talk about these boxes in association with the tail wing generally, is there a likelihood or possibility that the pinger which is on the outside there could get damaged and perhaps they could never hear it?

This point. >> okay. there are at least two u.s. warships in that area. the "u.s.s. ft. worth" that just arrived. and you talk about the sonar capabilities. the sonar, we understand from which ship actually located four more items. how might the sonar help detect the black boxes? and would that typically be the way in which those black boxes are located? >> well typically, you dont use sonar to detect the black box, or the sonar or the ping from the black box should show up on the sonar record. ...
