Enjoy night diving with your buddies? See and be seen by other divers in the dark, thanks to Aqualung's “color ID beam deflectors." SEAFLARE users can add a blue, yellow, pink or glacier color beam deflector to your light beam. You won't be mistaken for another diver ever again. The silicone, glow-in-the-dark color beam deflectors are collapsible and help to reduce the “light pollution" so you can focus on what you want to see - without blinding others.
