## Overview

The Coast GX20 is a tactical-grade LED flashlight delivering up to 1200 lumens with patented PURE BEAM optics and twist focus technology. It offers dual power options—standard AAA alkaline batteries (included) or a rechargeable ZX750 battery (sold separately)—and is built tough with an IP67 waterproof and dustproof rating. Featuring a textured grip and anti-roll tail cap, it ensures secure handling and stability. Perfect for professionals and outdoor enthusiasts seeking versatile, high-performance lighting backed by a lifetime warranty.

## Description

Shine bright through the elements. Built waterproof with an ultra-strong, lightweight polymer handle, the GX20 flashlight goes big on brightness and never backs down. This go-anywhere light offers four modes—medium, high, Turbo, and low—with a max output of 1200 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 even 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 that 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 four AAA alkaline batteries but can also operate using a COAST ZITHION-X ZX750 rechargeable battery (purchased separately). The GX20 is constructed of top-grade materials to meet IP67 waterproof and dust-resistant standards and is backed by a lifetime warranty.

## Features

- 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.
