VEVOR Mini Scuba Tank with Sub-Mask, 0.5L Portable Diving Tank for Underwater Breathing, Reusable Lung Diving Cylinder up to 10 Minutes Dive Time, Emergency Rescue Pony Bottle with Pump for Snorkeling

Complete 0.5L Capacity Mini Scuba Tank and Mask Kit with 5-10 Minute Breathing Duration 

This mini scuba tank and mask set includes an aviation-grade aluminum 0.5-liter (0.13-gallon) tank, a full-face mask, and a manual high-pressure pump that provides 5 to 10 minutes of air. The system can reach depths of up to 9.8 feet (3 meters), ideal for shallow-water exploration, beach use, and light diving. All the parts that come with the kit weigh 9.7 pounds (4.4 kg).

Breathing duration varies with dive depth and individual respiration rate, with typical users experiencing 7-8 minutes at moderate exertion levels. The Φ2.4 x 11.8-inch (Φ60 x 300mm) tank's size and 0.2-inch (4mm) wall thickness make it easy to move around without compromising its structural integrity. The all-in-one system comes with a portable carrying bag and a manual high-pressure pump that measures 24.6 x 10.4 inches (625 x 265mm).

Aviation-Grade Aluminum Construction with Mini Scuba Tank and Mask 20MPa Pressure Rating 

The tank is constructed from aviation-grade aluminum that can withstand a maximum filling pressure of 20 MPa (about 2900 PSI) and will not rust in saltwater. The M18 x 1.5 thread specification ensures safe connections, and the 0.2-inch (4mm) wall thickness keeps the structure strong even after repeated pressurization. 

The pressure relief disc helps safely release excess pressure before it becomes too high. The improved breathing valve has precisely manufactured parts that ensure smooth airflow and reduce inhalation resistance. The silicone mouthpiece resists wear and maintains flexibility over repeated use. 

180-Degree Panoramic Full-Face Mask with PC Lens and Liquid Silicone Seal 

The polycarbonate (PC) lenses in the full-face diving mask provide 180-degree views, are impact-resistant, and remain clear. The anti-fog layer helps maintain visibility during long dives, and the design that prevents water from entering keeps it out. The liquid silicone edging creates a waterproof seal without any pressure points that would be uncomfortable to wear for long periods.

The two sets of breathing tubes allow breathing on the surface through snorkel tubes or underwater by connecting to an air tank. The quick-disconnect design lets you switch modes quickly without taking off the mask. The camera bracket on top can hold action cameras, so you can take pictures and make videos underwater without using your hands. 

Dual Breathing Mode System with Seamless Air Supply Switching Capability 

The flexible breathing system has two separate modes that provide flexibility in the water. The surface breathing mode uses two snorkel tubes, so you can swim for longer without using up your tank air. Through a detachable breathing tube, the underwater breathing mode links directly to the 0.5L tank, letting you explore underwater up to 9.8 feet deep.

To change modes, you only need to separate and reconnect the tubes; you do not need to make any complicated valve adjustments. When the air in the tank runs out, users can easily breathe again through the snorkel ports on the surface. 

Three Refilling Methods with 400-600 Pump Strokes and 8mm Connector Interface 

Three different ways of refilling the tank are available to suit different access situations. The foldable manual high-pressure pump that comes with the kit requires 400 to 600 strokes to fill the tank, allowing you to refill the tank without external power. The pump includes a built-in pressure gauge that lets you monitor the filling process and prevent pressure from rising too high when you manually refill.

The refill port is a 0.3-inch (8 mm) male fitting and can connect to standard diving tank refill adapters for larger dive tanks (adapter not included). Compatible air compressor systems give people who have access to powered tools the fastest way to fill up. 

Lightweight Portable Design with Detachable Components and Airline-Checkable Transport 

All of the parts come apart completely and fit inside the carrying bag that comes with the kit, making it easy to take to the beach, boats, and other travel settings. The small storage arrangement takes up very little room in your luggage and keeps parts safe while you transport them. The empty, movable scuba diving tank may be transported as checked luggage, subject to airline regulations.

The total system weight of 9.7 pounds (4.4 kg) is manageable for long trips over rough terrain. The carrying bag design makes it easy to store when not in use and keeps all the parts safe and organized. 

Emergency Backup Air Supply for Boat Operations and Water Safety 

The mini scuba tank and mask system gives boat operators, water sports instructors, and marine workers who need to get underwater right away a reliable backup air source in emergencies. The 5–10-minute air supply is long enough for sudden entanglement situations, underwater hull inspections, or the retrieval of emergency tools back on board. 

Professional uses include pool maintenance, yacht maintenance, pier inspection, and shallow-water rescue. The small size makes it easy to store on board without taking up valuable deck space. Simply checking the pressure before deploying the system keeps it ready and makes sure it is immediately available in case of an emergency.

Beginner-Friendly Operation with Pool Training and Reef Exploration Applications 

The simplified operation makes this mini scuba tank and mask accessible to beginners with appropriate training. Before going out into open water, new users can practice breathing underwater in a controlled setting during pool training lessons. 

Reef exploration uses the system's ability to move around easily in shallow coral environments where regular dive gear is hard to use. The compact size helps improve control in delicate environments like coral reefs.
