The new Nova 850 Wide delivers the same illumination and offers the same features as the Nova 850, but is equipped with a wider 80º beam, making it the perfect primary night diving light. It is machined from heavy-duty aluminum with a rugged matte black finish so is both lightweight and built to last. It’s also easy to use. A 50% mode allows you to increase burn time if you don’t need the full power. For divers looking to brighten their night dives by illuminating large expanses of underwater terrain, the Nova 850 Wide is a winner. The Nova 850 Wide is powered by 3 C cell disposable or rechargeable batteries (not included).
