Discover the quiet, comfortable, bubbleless diving of a closed circuit rebreather. Rebreathers provide warm, moist breathing air at consistently optimum nitrox levels allowing for extended bottom times. The Poseidon Mark VI is the first and simplest to use closed circuit rebreather designed specifically for the recreational diver. Its automation and simple display make it easy to operate.
The Poseidon Rebreather Event is on June 21 & 22. To register, contact Aquatic Adventures of MI
