Underwater Text Messaging

An intriguing article in Israeli newspaper Haaretz describes a new gizmo recently developed to allow wireless communication underwater, between divers. The underwater text-messaging device, according to the article, works using ultrasound and has been provided to U.S. Navy “special forces”.

I tried to find more details of this interesting device, but couldn’t. It’s not cheap – around $1200 per device – and I doesn’t appear to use any sort of encryption or other keying mechanism to ensure privacy. Then again, the range is undoubtedly pretty limited, and the simple, pre-programmed codes most likely aren’t exactly a huge intelligence bonanza for the world’s spy agencies. Still, I expect that some Chinese or Russian boffins are already at work, developing a hull-mounted submersible ultrasonic detector to help detect devices like these; that is, after all, the way the technology race works…
