This Amphibico 3 x 4" Bluewater Filter (UR Pro) is a color correction filter for use in warm blue salt water. It alters the color, giving it a rich, natural tone. It also enhances the contrast of underwater video and photographs.
The filter slides into the outside filter holder on all Amphibico Dive Buddy EVO housing's lens ports. It works exceptionally well in shallow depths up to 60'. The filter should be used with available light only.
