Coast Products Gx10 Flashlight 550 Lumens W/Pure Beam & Twist Focus Black

The Coast GX10 is a compact 550-lumen flashlight designed for hunters, shooters, and outdoors enthusiasts who need reliable light in a pocket-sized package. At just 5.25 inches long and weighing 4.37 ounces, this waterproof tactical flashlight delivers serious brightness without the bulk. Whether you're checking a stand before dawn, inspecting gear at camp, or navigating in low light, the GX10 pairs raw output with genuine versatility—all backed by durable construction and dependable battery options.

The standout feature is Coast's patented PURE BEAM optic system paired with a TWIST FOCUS mechanism that lets you shift instantly between a wide, even Ultra View Flood Beam for close work and a focused BULLS-EYE Spot Beam that throws light downrange. Four output modes—low (73 lumens), medium (170 lumens), high (360 lumens), and turbo (550 lumels)—let you dial in brightness for the situation while managing runtime. On low, you'll get up to 18 hours of light; turbo mode delivers full punch when you need it. Beam distances range from 203 feet on low to 580 feet on turbo, so you can see what you're aiming at or spot movement at distance.

Build quality matches the performance. The GX10 is sealed to IP67 waterproof and dust-resistant standards, so rain, splashes, and submersion to 1 meter won't wreck it. The polymer body is over-molded with textured rubber grip that won't slip even in wet hands, and a lanyard loop doubles as an anti-roll tail cap—set it down on uneven ground and it stays put. The flashlight ships with three AAA alkaline batteries already installed, so you can use it right out of the box. If you want rechargeability, it's also compatible with Coast's ZITHION-X ZX557 rechargeable battery (sold separately), giving you flexibility to match your field setup.

Frequently Asked Questions

Can the Coast GX10 be used in wet conditions or underwater?

Yes. The GX10 is sealed to IP67 standards, meaning it's waterproof and dust-resistant. It can be submerged to 1 meter (about 3 feet) of water, making it reliable in rain, splashes, and brief submersion. For extended water exposure beyond that depth, we'd recommend keeping it in a dry pouch.

What batteries does the GX10 use, and can it run on rechargeables?

The flashlight ships with three AAA alkaline batteries installed and ready to go. It can also operate with a Coast ZITHION-X ZX557 rechargeable battery (sold separately), so you can switch between disposable and rechargeable depending on your needs and the mission.

How far does the beam reach on the GX10?

Beam distance depends on the output mode. On low, it reaches about 203 feet. Medium throws about 328 feet. High hits 475 feet. Turbo mode (550 lumens) extends the beam to 580 feet, giving you serious reach for spotting or tactical work at distance.

What's included in the box?

The Coast GX10 arrives with three AAA alkaline batteries installed, plus an alkaline battery cartridge. No separate purchase is needed to start using it immediately.
