Review: Not working - Tank leaked Review: Don't buy - All I need to say is in the comments ## Features - Compatibility: When these scuba tanks are used with a compatible diving mask, the snorkel mask draws air from the outside when on the surface, and when underwater, the air from the diving tank automatically fills the inside of the mask, allowing you to breathe freely through your nose and mouth. Whether snorkeling along vibrant coral reefs or conducting shallow dives in tranquil lagoons, it will provide users with the flexibility to immerse themselves in different aquatic environments. - Convenience: Mini scuba diving tanks offer convenience like no other. This scuba tank can hold 3.5cuft of air at a pressure of 3000psi, which can be used underwater for about 5-10 minutes. They eliminate the need for bulky dive gear and extensive setup processes. With a mini dive tank, divers can enjoy quick and easy access to underwater exploration. Whether it's a snorkeling trip, a shallow dive, or underwater photography, these small scuba tanks provide hassle-free diving experiences. - Safety: While scuba air tanks are smaller in size, they are engineered with safety as a top priority. This diving tank is made of aviation aluminum and is equipped with reliable pressure gauges, valves, and regulators while using a more stable constant pressure breathing valve to ensure proper functioning and air supply during dives. They are rigorously tested and DOT-certified to guarantee the safety of divers. With mini diving tanks, divers can go on underwater adventures with peace of mind. - Instructions for use: This gas cylinder needs to be assembled by yourself, and there is no gas in the bottle. There is a multi-layer filter device at the gas cylinder interface to prevent dust and impurities from entering the bottle. The bottle head is equipped with a switch to freely control the in and out of the gas in the bottle to prevent accidental leakage. The manual pump in this set can inflate this device, but it takes more than six hundred times to fill a 0.5L scuba tank. - Package contents: Includes a 0.5L gas cylinder, a constant pressure breathing valve, a high-pressure hand pump, a big handbag, a full-face mask, a mask adapter, and an anti-lose rope. We provide 24-hour online service and lifetime customer support if you have any questions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CW941D2C | | Best Sellers Rank | #207,458 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #25 in Diving Tanks | | Brand Name | UNAROWHALS | | Color | D005 D Black | | Customer Reviews | 3.0 3.0 out of 5 stars (18) | | Date First Available | February 23, 2024 | | Item Package Dimensions L x W x H | 24.76 x 9.96 x 3.27 inches | | Item Weight | 3.95 Kilograms | | Manufacturer | UNAROWHALS | | Material | Aluminum | | Package Weight | 3.95 Kilograms | ## Images ![Mini Scuba Tank with Pump, 5-10 Minutes Scuba Tank with Mask, Portable Diving Tanks, 0.5L Lung Tank Dive Tank - Image 1](https://m.media-amazon.com/images/I/61KXT3+58ZL.jpg) ![Mini Scuba Tank with Pump, 5-10 Minutes Scuba Tank with Mask, Portable Diving Tanks, 0.5L Lung Tank Dive Tank - Image 2](https://m.media-amazon.com/images/I/71A5MiYmioL.jpg) ![Mini Scuba Tank with Pump, 5-10 Minutes Scuba Tank with Mask, Portable Diving Tanks, 0.5L Lung Tank Dive Tank - Image 3](https://m.media-amazon.com/images/I/71dfJl4b9kL.jpg) ![Mini Scuba Tank with Pump, 5-10 Minutes Scuba Tank with Mask, Portable Diving Tanks, 0.5L Lung Tank Dive Tank - Image 4](https://m.media-amazon.com/images/I/71TnTLxDNNL.jpg) ![Mini Scuba Tank with Pump, 5-10 Minutes Scuba Tank with Mask, Portable Diving Tanks, 0.5L Lung Tank Dive Tank - Image 5](https://m.media-amazon.com/images/I/71-im2acawL.jpg) ## 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.
