If you engage in any water activity with a GoPro (or any other action camera for that matter), you know that condensation will build up quite quickly on the inner side of the case. This is because of the temperature drop that chills the water vapor trapped in the case.
The DIY option is quite easy, and dirt cheap:
- step 1: Cut strips about 0.75″x3″ from a paper towel, and fold them up to little squares.
- step 2: friction fit a few of those between the camera and the case.
- step 3: No more foggy GoPro clips
Ho Stevie goes through the process of comparing a case with some towel paper and without in a fridge and his solution totally works.
