Removable underwater colour-correction filter for the SportDiver that restores natural underwater colours. 

The Red colour filter is designed for blue water conditions and is most effective at depths of 3m to 18m, when not using an external light.

The Yellow colour filter is designed to restore natural underwater colours, or block blue light while using Fluoro or UV lights. 

The Magenta colour filter is designed for green water conditions and is most effective at depths of 3m to 18m, with or without an external light.

The filter easily attaches/removes to the SportDiver optical lens frame while underwater. Made of optical acrylic infused with proprietary colour pigments. Includes lanyard for attaching the filter to the housing. The filters also serve as a protective cover for the SportDiver's optical glass port.
