The Magenta Dive Filter for Standard Housing from GoPro is a colour correction filter designed to remove green colour cast while using the camera in green waters and is ideal for freshwater lakes and reservoirs or salt water that appears green due to algae content. It works best when used at depths between 15 and 70'. The filter is specifically for the Standard Housing and Blackout Housings for the HERO3 HERO3+ and HERO4; if you will use the Dive Housing a different filter is required.
The filter snaps into place for tool-free installation and features scratch-resistant optical-grade glass designed to ensure optimal image clarity. A tether to secure the filter to the housing and a carrying bag are included.
