Hi Shari, I highly recommend getting a floater strap an additional battery. The strap will save it if the camera ever falls out of the kayak and into the water. The extra battery is just great to have.
I bought the Chums floating strap to go with it, but I have yet to use it. Its a little bulky, but I guess it has to be to keep the camera from sinking... I would definitely want some sort of floating strap. I would hate to donate such a nice camera to the sea.
Get a flotation wristband attachment. I got one from Walmart. Mine if you search was yellow Olympus float strap. Any brand is good. I liked this whole I snorkels with my daughter because if she needed help I let the camera float so I was free hand
Definitely get a floating wrist band. I got mine on Ebay for about six bucks. Did save me on a snokeling trip in Cozumel Mexico when I dropped the camera. Kept it floating at the surface instead of sinking like a rock.
Buy an extra battery and a strap that floats. The battery life was poor in this camera and I would run out in less than 3 hours.I also had a strange smudge image in my pictures despite cleaning the lens. I eventually returned the camera. Consider the Nikon aw100 or the Panasonic lumix TS20. Amazon is offering great buys right now. Good luck
There are not a lot of accessories that would be pertinent. It comes ready to go. The only thing I would definitely suggest is an additional battery or two. The camera comes with one battery, but I know from experience there is nothing worse than being on a day-trip and missing opportunities due to a dead battery.
