Now that I’m old, I was looking for a scuba that’s light weight that I can check out potential dive sites in Riviera Maya. This tank flips the bill. Weighs nothing under water. The built in regulator works and feels like my old scuba pro mark V. Very easy breathing. Purge works very well, but not really needed as there is minimal water to purge. Normal full breathing, air supply at 3,000 psig lasts 9 minutes in 10’ water depth. Also, very easy to feel when last two breaths are coming up, but also have a gauge to go by. When gauge hits red mark, there is about five or six full breaths left in bottle. Only takes 12 minutes to fill using a small compressor. ## Features - UPGRADED CONSTANT PRESSURE BREATHING SYSTEM: Unarowhals scuba tank feature an upgraded constant pressure breathing system, ensuring a consistently stable airflow for smoother breathing and a better diving experience. - SUPERIOR MATERIALS: The cylinder body is made of aerospace-grade 6061 aluminum alloy, making it lightweight, compact, and highly resistant to pressure and corrosion.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressed *by J***V on June 25, 2024* Been scuba diving since 1975.
