0.5L Mini Scuba Tank

Ten Minutes Between You and the Deep. Make Them Count. Portable Refillable Dive Air System with 180° Mask & Pump

There's a specific kind of frustration that every diver knows: the moment you spot something extraordinary below the surface — a cave entrance, a wreck detail, a school of fish moving like a single silver organism — and your lungs are already burning. You surface. The moment dissolves. The ocean keeps its secret.

The OMNITHRILL 0.5L Mini Scuba Tank exists to close that gap. Not to replace your full rig — to extend your reach. Compact enough to clip to a BCD or drop in a dry bag, this aviation-grade aluminum cylinder gives you 5 to 10 minutes of clean, breathable air at depths down to 32.81 ft (10 m). That's enough time to drop back down, get the shot, explore the ledge, or pull someone to safety. In the water, ten minutes is an eternity.

This is the tank for the diver who doesn't accept "I'll get it next time." The snorkeler who wants to go just a little deeper. The freediver who wants a backup that actually fits in their kit. And the emergency responder who needs a reliable, portable air source that's ready when everything else isn't.

Built from pressure-resistant, corrosion-proof aviation-grade aluminum with a food-grade silicone mouthpiece that won't crack under pressure — literal or otherwise — this is a piece of gear engineered to be there when it matters. Rated to 20 MPa max pressure. Assembled in minutes. Refillable three ways. Ready for the water before you are.

Why You'll Love It

• 5–10 Minutes of Underwater Air at 32.81 ft (10 m): Not a novelty — a genuine emergency backup and leisure dive extender. Drop back down when your lungs say no. The tank says yes.
• Three Inflation Methods — Manual Pump, Supplemental Adapter, or Air Compressor: Fill it at the dive shop, at the surface, or in the field. No single point of failure. No excuses for showing up empty.
• Aviation-Grade Aluminum Construction (20 MPa Rated): The same material standard used in aerospace applications. Pressure-resistant, salt-resistant, and built to outlast the trips you take it on.
• 180° Full-View Anti-Fog Mask Included: Wide-angle, leak-proof, and treated against fogging — because the whole point of going deeper is actually seeing what's down there. No tunnel vision. No blind spots.
• Integrated Sports Camera Mount: The mask ships with a camera mount on top. Hands-free capture at depth, no housing rig required. Document the dive without sacrificing the dive.
• Fully Packable, Travel-Ready System: All components — tank, mouthpiece, pump, mask — break down and store in the included carrying bag. It fits in a backpack. It clears airport security. It goes everywhere your next adventure takes you.

Imagine It In Your Element

Scene 1 — The Reef Drop, Koh Tao: You're snorkeling the outer reef when you see it — a hawksbill turtle resting on a coral head at 8 meters, completely still, completely unbothered. Your freedive training gets you halfway there before the pressure builds. You surface, clip the mini tank to your lips, and drop again. This time you make it. You hover two meters away, camera rolling, watching the turtle blink slowly in the blue light. You stay for six minutes. The turtle doesn't move. Neither do you. This is why you carry the tank.

Scene 2 — Gear Bag, Pre-Dive Check: The full rig is already on the boat. But the mini tank sits in the side pocket of your dry bag — charged to 20 MPa, mouthpiece sealed, mask folded flat. It's your backup, your safety net, your "just in case" that you hope you never need and are deeply glad you have. You run your thumb over the aluminum body — cold, solid, reassuring — and zip the bag. Some gear you carry for emergencies. Some gear you carry because it changes what's possible. This one does both.

Go Back Down. Stay Longer. Miss Nothing.

The ocean doesn't replay its best moments. The turtle moves on. The light shifts. The school of fish scatters. The only way to be there when it matters is to carry the gear that makes "one more dive" possible. The OMNITHRILL 0.5L Mini Scuba Tank is that gear — compact, reliable, and ready to extend your time in the one realm where everything else goes quiet. Every Rush. Every Realm. — this one starts at the surface and ends wherever your air takes you. Make it count.
