Snake River Prototyping BlurFix3+ 55 Adapter with CYD Filter for HERO3/3+/4 Camera Housing

The Snake River Prototyping BlurFix3+ 55 with URPRO Cyan Dome (CYD) filter for the HERO3/3+/4 standard housing is best filter adapter and color-correction product for a GoPro camera yet! The URPRO Cyan Dome filter is pre-installed in the BlurFix3+ 55 adapter. The patent-pending CYD filter provides consistent color correction from center-to-corner and is specifically designed for use in tropical blue water between 12 and 60' in depth (color is improved at even greater depths depending on water conditions). The BluFix3+ 55 takes the best features of the BlurFix3 SO (slip-over adapter for the HERO3/3+/4 dive housing) and the original BlurFix (for the Hero and HERO2 standard housing). The filter adapter can be used in three configurations with/without included o-rings: unsealed, sealed/air filled and sealed/liquid filled. Unsealed Use When used without one of the O-rings, the BlurFix3+ 55 acts as a "wet filter" adapter. Holes at the top and bottom of the filter easily allow the space between the filter and housing to flood. This configuration is commonly used during dives with a color-correction filter. It's also the easiest configuration to use on land when rain, mud or snow intrusion is not probable. Sealed / Air Filled Use In environments where rain, mud or snow may be forced between the filter and camera housing, the space between the housing and filter is best off sealed. And this is easy to do if using the correct size O
