I have a GoPro HD Hero 2 waiting under the tree which Santa has brought me 
but this summer I'm off to Greece sailing for two weeks and basically will be using my GoPro for almost 100% underwater use. I also do a lot of kayaking and outdoor swimming etc. and the standard curved lens does not offer focused videos.
So, Iv'e been youtubeing many videos for flat lense kits to attach to GoPros. Theres a few different options to do either 100% homemade, DIY installation of a bought lens or buy a housing with lens pre-fitted.
Anybody had any experience with this and any advice?
cheers
(I'm really not sure how to spell lens so sorry if its wrong)
