The perfect size of the bottle with a diameter of 6 cm is very suitable for taking with you. After the diving bottle has been disassembled, you can take it on the plane and go diving anywhere.
Three ways to inflate: the working pressure of the diving bottle is 3000 Psi/200 Bar/20 MPa. There are three ways to inflate: the first method is to use a filling adapter that is in contact with the large bottle to guide the small bottle. It can normally be filled in 6 seconds. The second method uses an electric compressor. It takes 10 minutes to fully fill the 0.5 litre bottle. The third method uses a hand pump. Filling takes about 600 pumps.
Switched to diving design: the diving suit is specially designed for diving enthusiasts. The full face mask is suitable for 0.5L diving bottles and combines the benefits of traditional snorkelling and diving. On the water, the air enters the mask through the snorkel.

Professional design: with the constant pressure air outlet device, the high-pressure gas in the bottle is decompressed and output through the decompression chamber. The included explosion-proof copper plate bursts when the pressure reaches the tipping point (5000PSI) and automatically deflates to reduce pressure, so you have a safe and better diving experience.
Long service life: the diving bottle is made of high-quality aluminium alloy, which is stable and resistant to pressure, rust, wear and corrosion caused by sea water thanks to hot extrusion, integrated casting, spray painting and high-gloss polishing.
