Introducing the GoPro Dive Filter for Diving Housing. Designed for use with the Dive Housing and Wrist Housing, the Red Dive Filter provides colour correction while capturing footage in blue salt water or clear fresh water at depths of 15′ to 70′ (4.5m to 21.3m). The Magenta Dive Filter provides colour correction while capturing footage at depths of 15′ to 70′ (4.5m to 21.3m). It’s ideal for freshwater lakes and reservoirs or salt water that appears green due to algae. It’s ideal for sunny, tropical locations like the Bahamas, the Cayman Islands and Hawaii. The filter snaps into place for quick, tool-free installation, and features scratch-resistant, optical-grade glass to ensure optimal image clarity. Includes a carrying bag and camera tether. Both lenses improve vide clarity however each colour works better under different water conditions.
