Q1: How long can this 0.5L mini scuba tank last underwater?

When fully filled to 3000 PSI, the 0.5L scuba tank can provide up to 5-10 minutes of breathing air. Actual duration depends on dive depth, water conditions, and individual breathing rate. This tank is a backup air source, not a primary scuba tank.

Q2: Can beginners or non-certified users use this tank?

No. This product is intended for certified scuba divers only. Proper training and knowledge of underwater breathing equipment are required to use this tank safely.

Q3: How do I inflate it?

You will need a high-pressure air compressor capable of producing 4500 psi, and you will need to ensure the air is dry and clean. Using a high-pressure manual pump, it would take over 500 cycles to raise a 0.5L cylinder to 3000 psi.

Q4: Can I use a regular air pump or tire inflator to fill it?

No. Standard air pumps, tire inflators, or low-pressure compressors cannot reach the required pressure and should not be used. Only professional high-pressure scuba filling equipment is suitable.

Q5: Has it been DOT certified?

Yes, all UNAROWHALS diving cylinders have passed DOT certification before they are allowed to be sold.

Buyer beware

Dangerous and irresponsible. There's a reason you need a class to start scuba diving. Decompression illness is no joke.
