So there is a market for scuba divers to carry down to debth if it will take the pressure of say 100 feet underwater in a sealed water proof bag. Lots of cases where lost at sea (see left behind movie for true story) where the divers are swept out to sea in strong currents and boat couldn't find them. You might want to test your product out and see if it will do the job.
I would say probably not. it is only rated at 5 meters for 60 minutes or 10 meters for 10 minutes.
