Ikelite filter 3.9 "to clip (for portholes with external diameter 99mm)
External filter adaptable to a flat Ikelite watertight porthole thanks to its rubber ring, which clips on the edge of the porthole.
The filter absorbs a portion of the blue or green color in depths between 3 and 15 meters, which rebalances the colors when using no flash or headlight.
