As many already know the GoPro HD (High Definition) Hero camera is unique in that it combines the ability to take high quality video with a low price, in a very compact unit which is most suitable for our application, shooting freediving and spearfishing video. This camera was originally conceived for taking point of view wide angle footage in extreme sports, none of which were really taking place underwater. Hence the Gopro has a problem, the curved lens of the waterproof housing doesn't allow the camera to focus underwater and all resulting footage is blurry. Once the problem was identified the solution was simple; the housing must have a flat lens. Do it yourselfers have come up with different ways to modify the housing for it to incorporate a flat lens, but until now there hasn't been a commercially available solution.
Pursuit has acquired a drop in replacement flat lens for the Gopro housing. It's made of Polycarbonate resin, an amorphous thermoplastic material noted for its outstanding impact strength, superior dimensional stability, glass-like transparency, excellent thermal resistance, and low-temperature toughness.
Replacement of the GoPro housing lens is as easy as undoing the screws, taking out the original lens and dropping in the new lens. There's only one position in which the lens can go in so there's no worry of positioning it wrong. There's a rubber seal between the lens and the housing, no sealant or gluing is required. When tightening the screws of the black plastic mounting ring it's recommend to do it in a crisscross pattern to tighten it down evenly.
Housing and lens disassembled, with new lens on top of the camera.
Housing and flat lens installed, original curved lens is next to the screwdriver.
It's recommended to try the housing at depth without the camera having stuffed tissue paper into the housing to clearly indicate a leak if there is any.

Pursuit is currently offering a special; the Gopro Hero HD naked camera for $259.99 includes a flat underwater lens. No additional purchase necessary, you'll be ready to start filming underwater GoPro HD HERO Naked - Pursuit Freediving & Spearfishing Gear The flat lens is also sold separately.
