Go small, go bright, go waterproof. The compact GX10 is built water-tight with an ultra-strong, lightweight polymer handle over-molded with grippy rubber. At just 5.25 inches long, this pocket-friendly light shines in four modes—medium, high, Turbo, and low—with a max output of 550 lumens. Use the COAST-patented PURE BEAM® optic and TWIST FOCUS™ system to transition seamlessly between the edge-to-edge clarity of the Ultra View Flood Beam and the long-range precision of the BULLS-EYE™ Spot Beam. No storm, splash, or submersion down to 1 meter (3 feet) will stop you. The grip-textured handle features a lanyard loop, which doubles as an anti-roll tail cap so you can set the flashlight down and not worry about it getting away on uneven surfaces. Engineered with COAST Dual Power technology, the flashlight runs on three AAA alkaline batteries (included) but can also operate using a COAST ZITHION-X™ ZX557 rechargeable battery (purchased separately). The GX10 is constructed of top-grade materials to meet IP67 waterproof and dust-resistant standards and is backed by a lifetime warranty.
