PolarPro’s Red Filter for the GoPro Hero4 and Hero 3+ cameraa helps you capture vibrant tropical colors while scuba diving. The GoPro has a difficult time registering colors underwater due to red light loss. Our Red Filter has a specific red formula which helps significantly improve underwater colors when diving from 15 to 80 feet in blue or tropical water. The Red Filter also quickly snaps on/off the camera for quick tool-free installation and removal. The new lens is constructed of a blend of optical lexan plycarbonate, meaning it is very difficult to break, while still retaining razor sharp optics. Be sure to grab our Red Filter before your next scuba diving adventure to ensure your once in a lifetime videos come out as bright and vibrant as possible.
