Coast Products Gx20 Flashlight 1200 Lumens W/Pure Beam & Twist Focus Black

The Coast Products GX20 flashlight delivers 1200 lumens of tactical-grade brightness in a rugged, lightweight package built for hunters, shooters, and anyone who needs reliable illumination in the field or at the range. This is a serious work light—waterproof to 1 meter (IP67 rated), with edge-to-edge beam control and enough runtime to get you through a long day. Whether you're scanning terrain in low light, setting up camp, or performing equipment checks before a hunt, the GX20 combines versatility with dependable performance.

What sets the GX20 apart is its patented PURE BEAM optic system paired with a TWIST focus mechanism that lets you instantly shift between a wide, even flood beam and a concentrated spot beam for distance. Four brightness modes—low, medium, high, and Turbo—give you control over light output and battery life, so you're not forced to run at full power when you don't need it. The Turbo mode peaks at 1200 lumens with a beam distance of 853 feet; dial it back to low for 18 hours of runtime on alkaline batteries, perfect for longer expeditions or camp duties.

Built from top-grade polymer with a textured grip and an anti-roll tail cap, the GX20 is designed to survive hard use. The lanyard loop doubles as a tail cap stabilizer—set it down on uneven ground without watching it roll away. Dual power technology means you can run it on four standard AAA alkaline batteries (included) or upgrade to a Coast ZITHION-X ZX750 rechargeable battery for repeated field use, though the rechargeable is sold separately. At just under 6 ounces, it won't weigh you down in a pack or on a belt.

This is a flashlight built for the real outdoors—hunting camps, tactical training, overlanding, or emergency kits. It's not marketing hype; it's a tool that works when conditions get rough.

Frequently Asked Questions

Can I use rechargeable batteries in the Coast GX20?

Yes. The GX20 is compatible with the Coast ZITHION-X ZX750 rechargeable battery (sold separately). The flashlight comes with four standard AAA alkaline batteries, so you can use it right out of the box. If you plan to use it regularly, the rechargeable battery option reduces long-term battery costs.

What's the difference between the flood beam and spot beam?

The patented TWIST focus system lets you transition smoothly between two beam patterns. The Ultra View Flood Beam spreads light evenly across a wide area—ideal for close-range tasks and general illumination. The BULLS-EYE Spot Beam concentrates light into a narrow, focused beam that reaches out to 853 feet in Turbo mode, perfect for scanning distant terrain or identifying targets at range.

Is the Coast GX20 truly waterproof?

Yes. The GX20 is rated IP67, which means it's waterproof when submerged to 1 meter (3 feet) and completely dust-resistant. It's built to handle rain, splashes, and accidental dunking without failure. This makes it reliable in wet hunting conditions, river camps, or coastal overlanding.

What batteries are included with this flashlight?

The Coast GX20 comes with four AAA alkaline batteries ready to use. If you later want to switch to a rechargeable option, you can purchase the Coast ZITHION-X ZX750 battery separately.
