Flashlight Beam Technology

Pure Beam Focusing Optic
Pack two powerful beams into one and seamlessly transition—with no halos or hot spots—between short and long-range viewing. COAST’s patented focusing technology adapts to your need. The Ultra View Flood beam delivers edge-to-edge clarity in a broad circle of light up to 11.5 feet / 3.5 meters across, and the Bulls-Eye Spot beam sends a sharp ray of light at a distance of up to 1151 feet / 351 meters, with a transitional halo around the spot to increase the effective viewing area.

Long Range Focusing Optic
See clearly near and far. With the Long Range Focusing Optic, the power to illuminate and scan nearfield objects combines with a piercing light that goes the full distance. The X-Range Spot beam shines COAST’s longest beam, lighting objects at up to 2762 feet / 842 meters. The Broad View Flood beam delivers an even, sweeping circle of light up to 7.5 feet / 2.3 meters in diameter at a distance of 6 feet / 1.8 meters.

Universal Focusing Optic
All the light you need at just the right size. The Universal Focusing Optic, designed for COAST’s smallest focusing lights, enables the clear, broad light of a flood beam and the tight, long-distance ray of a spot beam. With the Max View Flood Beam, you get a crystal-clear circle of light up to 8 feet / 2.4 meters in diameter at a distance of 6 feet / 1.8 meters, while the Long Distance Spot Beam provides targeted visibility at up to 305 feet / 93 meters.
Flashlight Design and Construction

Slide Focus
Control beam shape with one hand. COAST’s Slide Focus system enables you to seamlessly transition between spot and flood beam with the push or pull your finger. Responsive beam-shape control allows you to operate your light with a single hand and keep the other hand free.

Twist Focus
Dial in the shape of light you need for the situation. COAST’s Twist Focus system makes it easy to move between spot and flood beams by simply rotating the head of the flashlight.

Beam Lock
Set your light to hold the beam just how you like it. COAST Beam Lock technology makes our Slide Focusing system even more valuable, with the option to lock the beam in place on spot, flood, or anywhere in between. Twisting the head of the light to the left locks the beam in place, and twisting it back to the right releases the slide mechanism back into motion.
Knife Technology and Construction
Max-Lock
Take safety to the extreme. COAST knives equipped with the Max-Lock system can lock the blade in either the open or closed position. Locking the blade closed prevents the assisted opening mechanism from accidentally engaging in your pocket. Locking the blade open protects your fingers from an accidental closure during use. Knives with Max-Lock also have a standard Liner-Lock to make the knives twice as safe.
Blade Assist
From closed to open in a flash. Knives with COAST’s Blade Assist mechanism use a proprietary opening mechanism to release the knife blade faster, smoother, and more safely than other blade-assist systems on the market. Operating Blade Assist is as simple as gently push the studs on the side of the blade until it pops open. Only available on knives equipped with Max-Lock.
Double Lock
One blade, twice the safety. During standard use, the Liner-Lock automatically engages and locks the blade open. But when you need to make more rugged cuts, push the Double Lock switch forward to block the Liner-Lock from possibly disengaging and allowing the blade to close on your hand. Adjust the safety detent-action (which controls how easily the knife closes) with the tension screw on the side of the knife. To operate, open the blade and push the switch on top of the knife forward to engage, or pull it back to disengage the Double Lock.
Liner Lock
Safe, single-handed blade control. Knives equipped with a Liner Lock use the knife’s interior stainless liner as a locking mechanism and allow you to keep one hand free while opening and closing the knife. To operate the lock, fully open the blade and the Liner Lock will automatically engage. To close the knife, turn the handle opening toward your body with the blade pointing away, push the ridged metal piece inside the handle to the left, and pull the blade back into the handle.
Frame Lock
Safe, single-handed blade control. Knives equipped with a Frame Lock use the knife’s frame as a locking mechanism and allow you to keep one hand free while opening and closing the knife. To operate, simply open the blade all the way and the Frame-Lock will automatically engage. To close, turn the handle opening toward your body, push the ridged metal piece left, and pull the blade back into the handle.
Lockback
Easily control your knife blade. COAST knives featuring the Lockback system have an easy-to-use, integrated lock mechanism on the back of the knife that ensures the blade stays open during use. To operate, simply open the blade all the way and the Lockback will automatically engage. To close, find the metal tab on top of the handle and push it in toward the handle, and then return the blade into the handle.
