Enhance your underwater photography with the removable Yellow color-correction filter for the SeaLife SportDiver. This filter reduces UV and excessive blue colors, restoring natural underwater hues or blocking blue light when using Fluoro or UV lights. It also serves as a protective cover for the SportDiver’s optical glass port. Designed for compatibility with the SeaLife SportDiver and SportDiver Ultra underwater smartphone housings, this filter easily attaches and removes from the SportDiver optical lens frame while underwater. Constructed from optical acrylic infused with proprietary color pigments, it ensures durability and clarity. The filter also includes a lanyard for secure attachment to the housing. For optimal performance in blue water, consider the Red Color-Correction Filter, item SL40007. For green water, try the Magenta Color-Correction Filter, item SL40003.
