Designed to fit the GoPro Hero9, Hero10, and Hero11 Black, this filter kit reduces or removes the propeller in most of the conditions encountered on a typical VFR flight. Mount it inside your cockpit to capture your flight without distracting propeller distortion ruining your video! This kit includes two filters: one for standard light (ND8) and an additional one for bright light (ND16). A soft pouch with dividers is included to protect your filters from scratches. HOW IT WORKS: The GoPro's image sensor is controlled by the amount of light it senses. In normal lighting conditions, the sensor runs faster than the propeller, causing distortion and odd lines in your video. This filter modulates the amount of light entering the sensor and keeps the speed of the sensor slower than the propeller. Since the amount of light changes constantly and the filter does not, we chose a Neutral Density filter that reduces or removes the propeller in 90% of the conditions experienced in VFR flight. For best results, we recommend avoiding shots straight into the sun. COMPATIBLE WITH: GoPro Hero9, Hero10, and Hero11 Black. Not compatible with any other GoPro. *Camera not included.
