Anish Patel of Dukane Seacom, the company that manufactures the pingers aboard Flight 370, tells CNN the pings detected by the Ocean Shield were actually at 33.3 mHz – a lower frequency than the standard locator beacon frequency of 37.5 mHz.

Mr. Patel joined CNN aviation analyst Miles O'Brien and Richard Quest of "Quest Means Business" to explain why the detected pings might have a lower frequency.
