The DiveMaster 3-Pack Filter Kit for HERO8 Black from PolarPro allows you to capture more accurate colors underwater. Included are snorkel, red, and magenta filters, designed to be attached to the protective housing for the HERO8 Black. They're for use in shallow, blue, or green waters, and each is fine-tuned for the HERO8's white balance to ensure optimal image quality. The filters each feature an optical polycarbonate lens and are made with a dual-lock snap and twist-mounting mechanism that allows for quick and secure swaps. The mounting mechanism incorporates an integrated thumbscrew that quickly locks/unlocks the filter.
