## Features

- 🏊【USING IT MORE SAFER】:SMACO S400 diving gear adopts a constant pressure air outlet device to make the air outlet pressure constant, making breathing very easy.At the same time, an external explosion-proof valve design is adopted, which makes the explosion-proof index more accurate and safer to use.

## Questions & Answers

**Q: How can you see how much bar/psi you have left if the gauge is on your back?**
A: For the S400 series, we recommend that you carry the bag on your chest to check the pressure gauge. If you don’t like this, I suggest you buy the latest S400 PRO, this one uses an extended pressure gauge and a waist pack, you can check it through the extended pressure gauge.

**Q: Is this a disposable mini scuba tank?**
A: no we bought this one on purpose so we can refill it

**Q: What about buoyancy? how can you control your buoyancy without bcd? will the tank drag you down?**
A: I deleted two answers... 

A filled tank (200 bar or 3,000 psi) - may it be S700, S400 1.0L or S300 - will go down to the bottom. It has a negative buoyancy.

An empty tank won't ascend from the bottom, but it will take an upside down position, its buoyancy is much less negative. 

Attached to you it "might" affect your buoyancy, but that depends on your own buoyancy. Buoyancy control depends on your buoyancy, and that from your weight, bodyfat ratio, gear weight, salinity etc.

**Q: Are these air tanks allow on planes**
A: Yes, if you can show that the first stage regulator is unscrewed from the tank.   Airlines are concerned with pressurized tanks.
