• With constant pressure and respiratory stability, beginners can also dive easily
• Constant pressure valve balances air pressure in the bottle, achieve constant pressure function, let the air flow out smoothly, breathing smoother, avoids wasting air
• The air switch valve can completely shut down the air source, no air leakage when storing it
• With a luminous pressure gauge, 80 meters underwater still can distinguish the pressure value at a glance
• The pressure gauge is made of stainless steel, waterproof and corrosion-resistant, high hardness and durable
• Designed with a food-grade silicone breathing mouthpiece, safe and odor-free. Ergonomic design, easy to bite and breathe
