Looks like a great find, hay I see a bit of gopro fogging?
Put the camera and housing open in the fridge for 10 mins then close the housing in the fridge & she'll be good.

Ta for the fog info. My mate was using the go pro and forgot to check the lenses for dried salt. The gopro 3 didn't fog. It just got salt on the lenses. Need to lick then lens every so often...
Polarised filters sound interesting. URL? Does that make the water look more clear?
