Tudiving 0.5L Mini Scuba Tank With Mask Portable Diving Kit For Training

This compact 0.5L diving tank with mask delivers 6–10 minutes of breathable air for training dives, depending on your breathing rate and depth.

• Portable design: 0.5L bottle with a 6 cm diameter is easy to carry; disassembly lets you take it on a plane.
• Durable, clean air: 6061 aviation aluminum resists seawater; fluorescent pressure gauge reads remaining pressure in low light; three-layer filtration keeps dust and impurities out.
• Diving-ready compatibility: the full-face mask fits 0.5L bottles; on the surface you breathe through the snorkel, underwater from the scuba tank.
• Certifications and operation: DOT/CE certified; safe depth about 33 feet; can be a backup air source for dives within 100 feet; inflate via 8mm interface using a fill adapter, electric compressor (about 10 minutes to fill), or hand pump.
