## Questions & Answers

**Q: Q1: How long can this 0.5L mini scuba tank last underwater?**
A: 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.

**Q: Q2: Can beginners or non-certified users use this tank?**
A: 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.

**Q: Q3: How do I inflate it?**
A: 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.

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

**Q: Q5: Has it been DOT certified?**
A: Yes, all UNAROWHALS diving cylinders have passed DOT certification before they are allowed to be sold.
