The Polar Pro Glass ND Filter features a slim, snap on/off design that fits the Underwater Housing and Skeleton Frame for the GoPro HERO3. It will reduce exposure levels while shooting in bright environments by 3 stops, allowing you to use lower shutter speeds and retain a more natural motion blur. In addition, a slower shutter speed can help reduce the apparent effects of vibration when mounting the HERO3 to an RC helicopter or vehicle.
The Glass ND Filter features a tether cord to help prevent loss, and a microfiber pouch to store it in.
