"Teledyne Benthos, a Falmouth-based company that creates a variety of undersea equipment, developed and manufactured the DPL 275 Locator — the device used by the Chinese ship that yesterday heard pings

"The device is typically used by divers, but was lowered into the southern Indian Ocean by a Chinese crew

"Teledyne Benthos’ officials are not convinced their device found the missing airliner and are running tests to assess the probability.

"The pulse was on the same frequency as the plane’s black box, but it is not conclusive evidence of the jet’s whereabouts, according to retired Air Chief Marshal Angus Houston, the head of the search coordination agency. Other experts also are not ready to jump to conclusions.

David Gallo, the director of special projects at the Woods Hole Oceanographic Institution, "said the Teledyne Benthos device is 'not normally the one that would be used to listen in deep water for something like this.' He said the ping could come from a number of other sources. 'It’s possible that it’s something biological in the water, and it’s possible that there was an operator error or the equipment was not tuned exactly right,' he said.
