Poseidon Mk IV Discovery Scuba Diving Tank
The Poseidon Mk IV Discovery Scuba Diving Tank actually extends the time you can be underwater by recycling your carbon dioxide exhaust and turning it into breathable oxygen. The Poseidon Mk IV Discovery accomplishes this with its C02 scrubbers and oxygen cells, which are powered by a lithium-ion battery. Plus, since it takes in the air you breathe out, you'll be able to dive stealthily without your bubbles alerting people to your presence. Not only will you be able to stay down longer, but your tank won't release any bubbles as you surface. Now that's stealth!
