our basic amateur SCUBA dives day or nite but especially at night included flashing beacons. which of course became invisible after about 25 ft in our NE waters at night. but I can only imagine the thing would have some kind of tracking system. but maybe the moronic designer used something else from a toy?
I suppose I was thinking of something more long-range than a flashing light!
Sonar pings? I don't know, I'm only speculating.
The MH 370 flight recorders were supposed to have some kind of beaconing that would be detectable underwater, but I don't know the range limitations of the technology. The problem with the missing plane was the massive and poorly-defined search area, as well as the short life-expectancy of batteries in the flight recorders. At least the release point and intended destination of the submersible were well-known. That's not trivilialse the challenges presented by the depth....
I was reading the news feeds earlier, apparently the submersible does have some kind of 'ping' and there was a report that a ping had indeed been detected. Fingers crossed for those on board.
