I talked about surf photography in my other post. I put together a small list of companies that make surf water housings. I use SPL water housing but I have used Mike Waggoner' s housings as well. All these manufactures make great products, it really comes down to what your needs are. SPL housings work great for my needs. Good luck if you have any questions please feel free to ask.
