The Polar Pro Red Glass Dive Filter fits the lens port of the GoPro HERO3+ 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'.
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.
