hmm well if that cam is foging inside the actuall cam housing with salt water,it will be very short lived. I bought a cam that was made to be water proff,not water ressistant like alot of the others,I thought you were talking about it foging inbetween a protective housing and the cam, mine did at first. check out helmetcamera.com and the protective cover that comeswith it,when the one you have craps out ,buy that system,it comes with a waterproff mic and lanc controll and waterproff hel cam and box for your main cam,under 600 bucks.worth every penny.
