SwitchBlade GoPro Hero3+ Red/Macro  Filter-Aqua3+-Scuba
The Polar Pro SwitchBlade3+ is a combination Red Filter and Macro Lens. The Switchblade3+ allows you to have a red filter for color correction in Tropical and Blue water, as well as a macro lens for close up shots along the reef. The filming options are endless wit this system. The red filter swings up and out of the way, for filming in shallow water. Then swings back in front of the camera for filming below 4 meters. The macro also locks open and closed, and any combination of the two lenses can be used. The entire unit slides onto the Hero3+ waterproof housing.
