We're all taught during our initial training that water filters out light. Conveniently we all learnt the colors of the rainbow which is the same order in which color disappears from the light which we are trying to capture with our cameras: Red, orange, yellow etc. You have to go pretty deep to start losing the greens and blues.
Adding a GoPro Dive Filter will cut out some of the unwanted color:
- A Red Filter will cut the blues.
- A Magenta Filter cuts the greens.
They come with a string lanyard that attaches the filter to the mount. Handy for the moments when you don't need the filter, such as when you are filming on the surface or at depths above 10 feet.
Personally I find that the simplicity of the filter is a good thing. You set it and forget it. Some of the other filter systems on the market have moving parts, small screws, hinges etc.
Keeping it simple adds an element of safety by reducing task loading and potential distractions.
If you are doing macro videography then you might want to go another way, but for everything else, the GoPro filters are well priced and do the job.
