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.
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.
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.
