Most promising lead yet in the hunt for flight 370. i spoke earlier with commander williams marks, he's the public affairs officer for the u.s. seventh fleet. remember, the u.s. is the one controlling the pinger locators. we got him from yokosuko. this is the most encouraging news we've heard. tell us what we know. >> well, it is encouraging. u.s. navy counterpart did detect a ping signal, actually, over a pretty significant amount of time in the search area. at first the cpl, or code pinger locator, heard a signal about 300 meters. that's pretty shallow. but it still is encouraging because so...

Breaking overnight in the search for flight 370, the signals detected by pinger locaters are those consistent with aircraft black boxes. what do we know about the pinger locaters used by the chinese and australian ship ocean shield. jeff weiss is here. you're here to discuss all these possibilities. >> right. >> the location these signals were detected, are you as optimistic as authorities in australia are that this could be what we're looking for? >> i would say guardedly optimistic remember this approach is a long-shot approach. the chances of finding something by acoustic ping without narro...

With surface debris is very small. as authorities say, miracle do happen. >> let's compare the chinese pinger locater as opposed to what's being used on board the "ocean shield." a tow locater. >> what the chinese are using is a system designed to be held by divers, so very shallow water. you sort of aim it in the direction that you think the ping might be located. it's very directional. >> so in a situation like this, that's a little risky to be using that for such a gigantic area. >> right. the manufacturers have told me it's barely -- operating right at the range of what is possible. it's o...

Shield has detected signals consistent with those of aircraft black boxes. >> the audible signal sounds to me just look an emergency locator beacon. >> reporter: the "ocean shield" picked up two distinct pinger alerts here. these signals detected 350 miles away from an area where a chinese ship picked untwo audio signals on saturday. britons "hms echo" has been moved there to investigate. they do not believe it's related to the "ocean field" find. >> i'd say it's unlikely. but in deep water, funny thing happen with acoustic signals. >> reporter: officials dress they need to find wreckage befor...
