A scuba certification is not required to purchase GEAROPT Mini Tank. We do strongly recommend all users to have scuba training to make sure you understand the risks and maximize your enjoyment when using it.
4.How long does it last?
The duration of GEAROPT Mini Tank depends on the person's breathing rate and depth. The 1-liter tank is filled to 200 bars, which equals 200 liters of breathable air at the surface (1 atmosphere of pressure). Here’s an approximate breakdown based on the average breathing rate of 12-20 breaths per minute:
- At the surface (1 atmosphere of pressure):
- A human breathes about 0.5 liters per breath.
- At 2 meters depth (1.2 atmospheres of pressure):
- A diver breathes about 0.6 liters per breath (0.5 liters × 1.2).
- At 200 liters, the tank provides roughly 166-200 breaths, lasting around 10-15 minutes under calm conditions.
Key Notes:
These estimates assume a calm breathing rate and no movement. Stress, exertion, or emergencies will increase air consumption.
GEAROPT Mini Tank is not intended for scuba diving use.
