This Ducame Purple Underwater Snap-On Filter for Gopro HERO 3+ HERO4 Standard Housing (Not Compatible with Hero 3) is a snap-on filter that is compatible with the GoPro HERO3 and HERO4 Standard Housing. The red color-correction filter is specifically designed to be used in tropical and blue-colored waters from 10-20m deep. The red coloring balances the overwhelming blue cast that is caused by the water in order to provide increased vibrancy and a more natural-looking white balance.
The filter is constructed from durable optical acrylic for increased protection and maintained image sharpness. The snap-on design also allows quick installation and removal of the filter while underwater.
