False alarm issued by the Chinese government and its reporter trying to show off. Instead it showed their weakness. From the Chinese reporter's video, I noticed a Chinese man on a rubber boat holding a Teledyne Benthos made pinger locator device similar to "Benthos DPL-275 diver hand-held pinger locator" with a yard-long stick. The locator was just few inches below the water surface. He tried to locate a black box which could be 2.5 miles below the surface. Benthos pinger locator is made for divers to communicate or to rescue purpose. It was a joke to use it to locate the black box. Teledyne Benthos is US company in North Falmouth, Massachusetts. They make excellent marine products.
