PURE BEAM FOCUSING OPTIC: Shine two beams from one optic—using PURE BEAM technology to transition seamlessly between Ultra View Flood Beam and BULLS-EYE Spot Beam. TWIST FOCUS: Adjust the beam shape—flood beam, spot beam, or anywhere in between—by twisting the bezel to focus the light. DUAL POWER: Power your flashlight how it suits you best—with standard alkaline AAAs (included) or a COAST ZITHION-X ZX750 rechargeable battery (purchased separately) for added convenience and savings over time. GRIP-TEXTURED HANDLE: Keep close control of your light with a firm grasp on the grip-textured handle. IP67 WATERPROOF: Shine through just about anything—with a light that stands up to dust and is waterproof against full submersion down to a meter.
