Perfect for shallow dives, snorkeling, and emergency backup, this tank combines safety, durability, and freedom for your underwater adventures. ## Description The unarowhals scuba diving tank is made of aviation-grade aluminum and uses an upgraded breathing valve core to provide you with a better user experience. At the same time, the diving tank has a three-layer filter device that can effectively prevent dust and impurities from entering, making the inhaled gas cleaner. All products are DOT certified, so you can use them with confidence. Its maximum diving depth is 33 feet, and it can be used as a backup air source for deep diving within a depth of 100 feet. Small diving tanks are suitable for underwater exploration, boat cleaning, emergency rescue, backup air source, etc. The use time of a 1L is 10-15 minutes, depending on your diving depth and breathing rate. Of course, no matter what capacity of diving cylinder, there are two ways to inflate: 1. Use the scuba adapter, 8mm inflation port, connect to a standard large diving tank, and your diving cylinder can be inflated in 10 seconds. 2.4500psi air compressor, 1L diving tank inflation, about 20 minutes to complete. Review: No instructions, very hard to use and fill. - I bought one in blue and my Fiancé got one in black. We got them back around Christmas and now that its summer we are trying to use them. Very confusing, doesn't come with instructions. Im pretty sure the black one is broken when you try and fill with air you hear the mouth piece hissing and the button doesn't release air. Plugged up the blue one to the compressor and its actually filling up but the mouth piece is also hissing and its taking a very long time to fill the valve goes up extreamly slow. Hopefully im doing it right since the are No instructions. Review: Simple to use. - Great product for the price. Need to pump non stop for 15-20 mins to completely fill though. ## Features - 【Constant Pressure Breathing Valve】（CPBV）: The scuba diving tank uses CPBV technology, which can provide a consistent air supply in different environments and diving depths to ensure worry-free underwater adventures. Compared with other diving tanks, constant pressure diving tanks allow your body to be more free and unrestrained in the water without worrying about changes in flow. - 【DOT Certified Aluminum Bottle】: Lightweight and durable, it offers unparalleled pressure resistance, superior corrosion protection, and versatile compatibility with scuba gear. All scuba tanks are DOT-certified to ensure safe and reliable diving. - 【5-10 Minutes】: 0.5L scuba tank has a maximum safe pressure of 3000 psi and holds approximately 3.5 cubic feet of air. After filling with air, you can start a pleasant underwater journey for 5-10 minutes, your diving depth and your breathing rate will affect the length of diving time. - 【High-Pressure Hand Pump】: If you don’t want to go to a dive shop or use a PCP air compressor to fill, this scuab diving gear includes a high-pressure hand pump, it’s time to show off your skills! The hand pump needs more than 500 operations to make the 0.5L diving tank reach the pressure value of 3000psi! Come on! - 【Wide Application】This mini diving tank is suitable for underwater work, snorkeling, deep diving, fishing, hunting, underwater sports, etc. Portable scuba tanks are also the perfect tool for outdoor travel underwater photography, and we recommend using the device in freshwater areas such as lakes or pools, or shallow sea areas.

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 ### ⭐ No instructions, very hard to use and fill. *by E***S on June 28, 2025* I bought one in blue and my Fiancé got one in black.
