Safety First
Use Responsibly
The GEAROPT 0.5L Mini Tank is intended for properly trained users and short underwater access in controlled shallow-water conditions within 3 meters.
It is not a replacement for full scuba training, standard scuba equipment or proper dive planning.
Always:
Read the product manual before use.
Use only clean, dry, breathable compressed air.
Do not exceed 200 BAR / 3000 PSI.
Use within 3 meters and within your training ability.
Check all connections before entering the water.
Do not use for deep diving, cave diving, wreck diving or professional underwater work.
Go Anywhere. Do Anything
With compact air support for quick moments just below the surface.
Protect What You Explore.
The ocean gives us freedom. It deserves our respect.
Every dive reminds us why clean water matters — for marine life, for future adventures, and for everyone who feels at home in the sea.
Go anywhere. Do anything. Leave nothing behind.
Built for Water. Made to Last.
The ocean gives us freedom, movement and stillness. But even what feels endless is more fragile than it looks.
At GEAROPT, we design water-sports products with long-term use in mind. We focus on durability, responsible maintenance and practical product choices that help reduce unnecessary waste.
From rechargeable audio products to reusable Mini Tank systems and refill accessories, our goal is simple: create gear that supports adventure while showing respect for the water that makes it possible.
