This 3-in-1 combo filter has a glass Red filter and a glass Macro lens, both which can easily swing away and be used in any combination.
The Aqua Glass Red filter captures beautiful deep blue hues as well as vibrant tropical colours that pop off the screen. It provides colour correction underwater from 10 to 85 feet. But, if you're diving shallow, simply flip the red filter up and use just the macro filter instead!
The Macro lens features a powerful 2.2X magnification and allows you to focus sharply underwater from 4 to 18 inches. The glass construction of the lens gives even higher durability against scratching. To see the true difference the Switchblade makes, check out the video below.
