How waterproof are action cameras?

Many resist water to a few metres without a case, with deeper diving needing a dedicated housing. Check the rated depth and rinse the camera in fresh water after sea use.

Do I need extra batteries and memory cards?

High-resolution filming drains batteries quickly and fills storage fast, so spares help on longer days. Use a fast, high-capacity card rated for the camera's video modes.

Will my existing mounts fit a new action camera?

Most cameras share a common finger-mount design, so many accessories transfer across models and brands. Check the fitting type, as some require a frame or adapter to attach.
