What is Nemo?

How does Nemo work?

Inside of Nemo is a custom battery-powered air compressor. The compressor pumps air to the diver through the 10-foot hose and out through our patent-pending Smart Reg™. Our Smart Reg saves battery life by monitoring breathing patterns to let the compressor know exactly when it needs to send air. This means Nemo doesn’t just push air to you, but rather breathes with you.
