SMACO S300 Plus 0.5L Mini Scuba Tank

Supports 10 Minutes of Breathing Time

The SMACO S300 Plus 0.5L Mini Diving Air Cylinder allows you to breathe underwater for up to 10 minutes, which extends underwater time and enhances snorkeling, perfect for quick underwater tasks, short dives and more. Excellent choice for diving experience, yacht maintenance, backup air source, suitable for boat owners to remove the anchor or check the hull, check the underwater structure and so on.

Three-layer Filtration Unit

SMACO S300 has triple filtration device, which can effectively prevent dust and impurities from entering and make the inhaled gas cleaner. (Note: Diving depth, temperature and breathing frequency will affect the usage time of the scuba).

Pressure and Corrosion Resistant

The SMACO S300 Plus is made of 6061 aircraft aluminum for better resistance to internal corrosion and damage.

Simple Operation

Equipped with an integrated regulator that screws directly onto the tank for easy assembly and ease of use. Simply place the mouthpiece in your mouth to free your hands and swim underwater.

Compact and Lightweight

The tank weighs 1.15 kg, making it easy to carry over long distances.
