The GOYOJO 0.5L Mini Scuba Tank is designed as a compact and portable option for short dives or training sessions, offering about 6 to 12 minutes of breathing underwater or roughly 66 breaths at shallow depths. Its 0.5-liter capacity is quite small compared to standard scuba tanks, making it best suited for beginners or those needing brief underwater access rather than extended dives. Made from durable aluminum with corrosion-resistant coatings, this tank is built to last and handles pressures up to 3000 PSI safely.

It includes useful features like a luminous gauge that's visible down to 80 meters, a pressure relief valve for safety, and a multi-filter system to ensure clean air. Weighing just over 7 kilograms with accessories, it remains relatively easy to carry, though not ultra-light for its size. The package is comprehensive, providing diving goggles, ropes, a manual pump, and other helpful gear, making it a convenient all-in-one kit for new divers or training purposes.

Its small tank size limits dive time and depth (recommended up to 10 meters), so it is not suitable for serious or longer scuba diving adventures. Users must be mindful to release pressure before flying and handle refills carefully. This tank serves well as a portable training or beginner device, but those needing longer, deeper dives should look at larger capacity tanks.

Some users find the fit challenging, which can affect comfort and balance during use despite the device's functional potential.

The HOUVAN Mini Scuba Tank with Snorkel Mask is designed for casual snorkelers and shallow divers who want to breathe underwater briefly without bulky equipment. Its 0.5-liter aluminum tank is lightweight and corrosion-resistant, making it suitable for use in seawater and easy to carry around. The tank provides about 6 minutes of air underwater, with a maximum safe diving depth of 30 feet. This makes it ideal for short, shallow dives but not for extended or deep dives.

One standout feature is the full-face snorkeling mask with a wide 180° field of view, which helps reduce distortion and discomfort during use. The mask separates inhaled and exhaled air channels to keep breathing smooth and fresh. The tank connects conveniently to the mask and can be removed for easy refilling or replacement, adding flexibility. An action camera mount lets you capture your underwater experience.

While the compact size and combination of snorkeling and diving in one set are clear advantages, the limited air capacity and short dive time mean it's not suited for serious scuba diving or longer underwater exploration. Users must also be mindful of depth limits to stay safe. The included mini hand pump and accessories make it user-friendly, but those seeking more robust performance should consider larger tanks. This product is well-suited for adult beginners or recreational users looking for a portable, easy-to-use air backup for snorkeling and shallow dives.

Capacity
The 2-liter tank lasts about 5 minutes during physical activities like cleaning a boat hull.
Buoyancy Characteristics
Buoyancy control is challenging without a BCD, but positive buoyancy can be helpful for certain tasks.

The SMACO S700 Mini Scuba Tank is a compact and portable scuba diving solution, designed for both beginners and seasoned divers who need a backup air source or a convenient way to explore underwater. With a capacity of 1.9 liters, this tank can provide up to 30 minutes of dive time, depending on conditions like depth and breathing rate. This makes it suitable for shallow water activities such as snorkeling, recreational diving, and even rescue scenarios.

One of the standout features of the SMACO S700 is its upgraded pressure gauge, allowing divers to easily monitor air pressure while submerged, enhancing safety. The included vest frees up your hands, making it easier to engage in various underwater tasks. The kit also comes with an aluminum hard case for easy transport, which is perfect for trips, including air travel.

It's essential to consider some limitations. The refill options are convenient, with the ability to fill the tank at local dive shops, using an 8mm adapter, or through a SMACO air compressor. Yet, it’s worth noting that a high-pressure hand pump cannot be used for refilling this tank, which may be a restriction for some users. Additionally, while the tank's lightweight design is a plus for portability, it may not be ideal for deep-sea divers requiring larger capacities for extended dives.

Buying Guide for the Best Portable Air Tank For Diving

Choosing the right portable air tank for diving is crucial for ensuring safety and enjoyment underwater. The right tank will depend on your diving habits, experience level, and specific needs. Understanding the key specifications will help you make an informed decision and select the best fit for your diving adventures.
CapacityCapacity refers to the amount of air the tank can hold, usually measured in liters or cubic feet. This is important because it determines how long you can stay underwater. Tanks with smaller capacities (e.g., 50-80 cubic feet) are lighter and easier to carry, making them suitable for shorter dives or beginners. Larger tanks (e.g., 100-130 cubic feet) provide more air for longer dives but are heavier and bulkier. Choose a capacity based on the duration of your dives and your physical ability to carry the tank.
MaterialPortable air tanks are typically made from either aluminum or steel. Aluminum tanks are lighter and more resistant to corrosion, making them easier to handle and maintain. However, they are bulkier and have a lower capacity compared to steel tanks. Steel tanks are more durable and have a higher capacity for the same size, but they are heavier and can rust if not properly maintained. Consider your diving environment and how often you dive when choosing the material.
Pressure RatingThe pressure rating of a tank, measured in PSI (pounds per square inch) or bar, indicates the maximum pressure the tank can safely hold. Higher pressure tanks (e.g., 3000-3500 PSI) can store more air in a smaller size, making them more efficient for longer dives. Lower pressure tanks (e.g., 2000-2500 PSI) are easier to fill and maintain but may require a larger size to hold the same amount of air. Choose a pressure rating based on your diving depth and the availability of filling stations.
Valve TypeThe valve type determines how the air is released from the tank and how it connects to your regulator. The most common types are DIN and Yoke (also known as A-clamp). DIN valves are more secure and can handle higher pressures, making them suitable for technical diving. Yoke valves are easier to use and more common in recreational diving. Choose a valve type that matches your regulator and diving style.
WeightThe weight of the tank is an important consideration, especially if you need to carry it over long distances or handle it frequently. Lighter tanks are easier to transport and manage, but they may have lower capacities. Heavier tanks can hold more air but can be cumbersome to carry. Consider your physical strength and the logistics of your diving trips when choosing the weight of your tank.
Buoyancy CharacteristicsBuoyancy characteristics refer to how the tank affects your buoyancy underwater. Some tanks are negatively buoyant, meaning they will sink, while others are positively buoyant and will float. Aluminum tanks tend to be more positively buoyant, while steel tanks are more negatively buoyant. Your choice will depend on your buoyancy control skills and the type of diving you do. Proper buoyancy is essential for maintaining control and conserving energy underwater.
