They might have both but the audio ones are the ones in play now.

That’s because acoustic beacons, or locator "pings" from the black box will probably fall silent within two weeks, Gibson told CBC News.

"At some point, the pinger will simply run out of power, and that’s usually in about 30 days," he said. "Once you figure out when the aircraft went into the water, you go 30 days from that point, and that’s its shelf life."

Phoenix International’s “Batwing-like” towed pinger locator (TPL) weighs about 31 kilograms and can detect a black box’s signal ping from about a mile (1.6 kilometres) away, Gibson said.

I know the sub thing is a long shot, but given all the secrecy regarding capability of military systems we have seen regarding this flight, it seemed appropriate.

You're exactly right. I'm sure I already knew they were acoustic pingers and I forgot somewhere along the way. Underwater locator beacon
