For a more detailed description of the BlurFix Air product line, reasons why filters are used with a GoPro® camera, and BlurFix Air in-depth instructions, click here
Each BlurFix Air is made from two CNC machined Delrin® pieces so that the filter frame can be disassembled to facilitate easy cleaning of the filter glass. Delrin, which is more costly than billet aluminum by volume, was selected because of its high quality and excellent machining qualities.
The Hero3/3+/4 lens body can vary slightly from camera to camera. To ensure a good fit, each BlurFix Air includes an optional o-ring that can be installed in a groove on the inside of the BlurFix Air body.
GIMBAL USERS: Refer to the gimbal manufacturer about safely using our products with your specific gimbal make and model. Not all gimbals can safely support extra weight. SRP will NOT be liable for damage.

What about ND32 or ND64 Filters?
Snake River Prototyping (SRP) do not offer a standard ND32 or ND64. ND64 is too much and results in noise and "muddy" footage. The SRP ND16/CP has the same light transmission as an ND32, with the added benefit of reducing unwanted reflections or glare. The ND/CP combo filters are as if you stacked a Circular Polarizer onto the ND, which adds nearly a full stop. So an ND8/CP and a standard ND16 would have similar light transmission or stop, and the ND16/CP would be very close to an ND32.
