TELESIN Underwater Housing & Lens Filter Kit for GoPro (Purple, Red & Magenta) GP-WTP-904

A polycarbonate housing rated to 148′, sealed with a rubber gasket and fitted with a tempered glass lens port, for the GoPro HERO9, 10, 11 and 12.

Water strips red light first, then magenta, then purple, which is why footage turns blue-green as you descend. The three included filters put those wavelengths back, so the colour is right on the card instead of being clawed back in the grade.

The 2-prong mount and mounting buckle drop straight onto the GoPro mounts you already own, and the whole housing weighs only 4.7 oz.
