Those are some great pictures, Chris. I know what you mean by being brave the first time you submerge it. I literally had to force my hand into the river the first time I used it. It felt like I was tossing my wife's iPod into the water.

I took one of those common boat key chains that has the float on one end of it where you can pop the top and put boat registration, money, etc. and attached that to the camera. It still doesn't float, but it doesn't sink like a rock to the bottom either.
