The Switchblade2.0 is a great scuba diving accessory for the GoPro diver. It combines a macro lens and a red filter making it one of the most versatile GoPro filters on the market. The all new Ultra-Macro lens provides 10x magnification which means underwater focus distance of 3 to 8 inches, and above water focus distance of 1.5 to 5 inches. The macro is incredibly powerful and has the ability to capture close up images and videos like never before. The PolarPro red filter provides precise color correction from 15 to 80 feet. The red filter and the macro lens can be used together, or separately. The redesigned engineering on the Switchblade2.0 includes a new macro latch system locking the macro open or closed, a new zinc rivet connecting the red filter to the base, and a overall structure boost, ensuring that your Switchblade2.0 will withstand rough diving conditions.
