The 55 mm URPRO Shallow Water Cyan (SWCY) filter utilizes URPRO's patented color-correcting technology. This filter is ideally suited for tropical blue salt water or clear fresh water at depths of 25 ft or less. We recommend the URPRO SWCY filter to snorkelers or shallow water divers who are headed to a tropical paradise somewhere in the world.. All URPRO filters sold by SRP feature an ultra low-profile filter ring in order to limit mechanical vignetting.
Note: Camera and filter adapter not included
