The Switchblade2.0 is the new redesigned version from Polar Pro guaranteed to live up to the harsh scuba environment. The new design utilizes metal rivets and a durable rubberized coating for improved strength. This is the perfect tool for scuba divers filming with GoPro cameras. Also improved is the macro lens, this macro is even more powerful and has a focal range of 3 to 6 inches underwater, perfect for capturing small reef critters. The Red filter is riveted onto the frame to ensure a solid connection and can be flipped open and closed depending on your filming depth. Both the red filter and the macro lens can be used together for stunning macro shots without using video lights. This filter is backed by a 6 month money back guarantee through Polar Pro. Take your scuba videos to the next level.
