The BlurFix3+ 55 Adapter with CYD Filter for Hero3+ Housing from SNAKE RIVER PROTOTYPING features a URPro Dome CY color-correction filter pre-installed on a BlurFix3+ 55 filter adapter, which slips over the GoPro Hero3+ standard underwater housing.
The CY filter provides consistent cyan color correction from edge to edge and is specifically designed for use in tropical blue water between 12 ft and 60 ft deep. (Color is improved at even greater depths depending on water conditions.)
The filter adapter can be used in three configurations with/without included o-rings: unsealed, sealed/air filled, and sealed/liquid filled. (Please see below for descriptions of the three.)
