SeaLife has released new color filters for their SportDiver smartphone housings. These filters include a red filter for general diving, a magenta filter for green water, and a yellow filter for fluorescence imaging. Each filter costs $20 and helps to correct color loss underwater, especially in the red spectrum. They are easy to attach and remove, and work well at depths between 10 to 60 feet. A lanyard is included with each filter to prevent loss while diving.
