The Snorkel Filter from PGYTECH screws onto the original lens of the DJI Osmo Action camera and is designed to ensure the camera retains proper white balance in blue or tropical waters by allowing more red light to pass through.

The Snorkel filter features SCHOTT optical glass with double-sided multi-coating to make the lens water, oil, and dustproof. It is recommended for depths down to 16.4'. The filter frame is made from durable aluminum and features knurling for easy mounting and removal. Since the camera itself is waterproof, you can use this filter without the waterproof housing. But if you intend to dive below 36', the camera's waterproof housing is required.
