Can new technology help me map my underwater fieldsite?

I need to make relatively precise measurements, to the nearest half meter, of locations on my field site, which is on the floor of a Mediterranean cove (not more than 10m deep). One possibility is to swim on the surface above my locations and use a GPS to record the points - but so far my older-model GPS's have not been accurate enough for this. I'm leaving in about a week, and just recently I was reminded that technology may have advanced to meet my needs, even since last year! Can anyone update me on the latest and greatest (waterproof) mapping instruments out there?
