The World's Smallest
Dive System
NEMO pumps only the exact pressure, volume, and flow rate that the diver needs at their particular depth. NEMO uses just a fraction of the energy of any other underwater breathing system. That’s why Blu3 can use smaller pumps, motors, and batteries – bringing you the most portable and affordable underwater breathing system ever!
