Neal,
I sure am glad you posted this. I am considering buying this particular camera. I am looking for a small, pocket sized, quality camera to replace my oooold Toshiba that finally broke after 10 years of faithful service.
I purchased an Olympus SP510-uz to take on a family vacation this past summer. It is a great camera and takes great pictures. It is just too big framed a camera to keep in your pack or pocket while hunting and fishing.
I also like the fact that the 770SW is not water resistant, it’s water proof. Like you said, it’s submersible up to 33ft. (35 by your calculations, lol)
Since you took it diving over 30ft, i’m sure it will do everything I want it to do. I am always worrying about taking a dive in my waders and ruining a camera.
