The Polar Pro Red Glass Dive Filter fits the lens port of the GoPro Standard Housing and is designed to ensure the GoPro retains proper white balance in blue or tropical waters. This glass color-correction filter is recommended for depths between 10 and 80'. It can be used with the Standard Housing for the HERO4 and HERO3+.
The filter is built into a slim frame that snaps on and off the lens port of the GoPro's underwater housing. It features a tether cord to help you avoid losing the filter while diving and a scratch-resistant microfiber pouch to store it in.
Because it is made of glass, care should be taken when handling and storing this filter.
