my 2 cents... emmmm pennies i mean....
if you want a cheap low budget poor quality video then go ahead and buy the gopro or whatever else is in the same league...i myself im using a the camera mask (broken up an mounted on speargun) cause im on a very very very low budget and i only did it for my 'amusement' ....
but you on the other hand, researching for a BBC2 program, which will be broadcasted i guess to the viewers save your self the hussle and get at least a semi-decent quality (resolution-wise) video-camera and appropriate housing. or if money is the problem get a normal camera with decent video capabilities+housing and shoot a video that will be worth shooting and worth to be watched by your viewers.
a low spec camera as the one mentioned is a :rcard:naughty
if you are on the other hand looking only for camera mounts, they are easy to 'construct' and each speargun will 'demand' its own setup, taking in consideration the 'user-spearo' (aiming, loading, camera etc) !!!
I thought we were trying to move from standard def to HD, and not to sub-standard def :blackeye
Best of luck with your tv program (also a quick search on vimeo or youtube will give you plenty of bad quality and good quality examples spearfishing videos) !!!

edit: just pating the link to my setup (the camera was sitting in my aiming line and now i have inverted the Π shaped aluminium part so that the camera sits a bit higher and i have a 'window' , an aiming window if you like from where i can track the fish and aim without obstructions...it also helps to conceal my shining mask lenses ' i think'
!!!!
