  • Comfortable dive harness

  • Accessible (compact and lightweight)

  • Air travel capable


10.75″ x 7.5″ x 8″ (L x W x H) without flotation tube (about the size of a 2-slice toaster)

Weight: ~10 pounds
Run time:  60+ minutes
Depth:  10 feet (3 meters)


  • 1 NEMO™

  • 1 BLU3 Smart Regulator

  • 1 Tow harness

  • 1 Battery Pack

  • 1 Dive flag

  • 1 Comprehensive Training Course


Each NEMO will include a comprehensive training program that covers safety and best practices of both snorkeling and scuba diving. These lessons will also be available on our website to be reviewed at any time.

Know when your battery is low
NEMO features a low-battery signal is programmed into the system to alert you when it’s time to make a safe ascent back to the surface.

The Buddy System
An important rule to diving of any kind is to never dive alone. So convince a buddy or a group of friends to go in on one of our 2 or 6-unit rewards and dive BLU3 together!


This feature-rich backpack was designed specifically to carry NEMO wherever the call of the water beckons. These stylish packs are made out of textilene – a sturdy and resilient material that looks great too. Intelligently-designed straps and pockets all around the bag keep your NEMO neat and tidy. 

The rollout mat provides a barrier between your equipment and the sand/surface. There’s a convenient spot for your fins on the outside of the bag, plus plenty of space inside for your mask, GoPro, phone, reusable water bottle, or anything else. This bag is everything we want and more.


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.

Electric Smart Regulator
The Smart Reg™

What allows NEMO to be so compact, energy-efficient, and responsive is our patent-pending Smart Reg™ – the first of its kind!

Here’s how it works: A silicone diaphragm inside the Smart Reg™ moves when the diver breathes. A waterproofed sensor measures the diaphragm movement – it then sends an electronic signal which triggers the compressor to pump air at exactly the time and speed that the diver is inhaling.

NEMO pumps only the exact pressure, volume, and flow rate that the diver needs at their particular depth which means it uses just 1/10 the energy of any other underwater breathing system. That’s why we can use smaller pumps, motors, and batteries – bringing you the most portable and affordable underwater breathing system ever!


The Compressor

We’re not just using some off-the-shelf compressor and sticking it in a box. NEMO’s compressor is an entirely custom design. We’ve built it specifically to ensure clean breathing air is supplied as efficiently and in as compact of a package as possible. Our engineers like to call the compressor an “oil-less linear two-cylinder brushless DC diaphragm pump.” Everyone else calls it “innovative.”


The Battery Pack

NEMO is powered by a custom lithium-ion battery pack that is swappable and rechargeable. The pack and connector are IP68-rated to handle saltwater environments. It’s under 100 Wh, so there are no issues with air travel! A charge-level indicator is located right on the battery itself so that you always know your battery level. Be sure to grab a few extra packs so that you can dive all day long!


BLU3 foam to dive without tanks

The Flotation Foam

NEMO’s flotation foam is made of cross-linked polyethylene and is shaped with a computer numerical control cutting machine. The foam is designed to give NEMO inherent buoyancy while keeping the main compressor unit in the water for cooling purposes.

The Flotation Tube

Designed to give NEMO extra stability and visibility in open-water settings such as the ocean, the flotation tube provides an additional 22 pounds of buoyancy and is brightly colored so that family, friends, and by-passers can easily spot your location while you’re diving. The tube inflates with only two breaths and similarly deflates with ease. Not diving in an open-water setting like an ocean or lake? NEMO will float just fine without the flotation tube!

The Air Hose

NEMO’s 10-foot air hose is the perfect balance of weight, flexibility, and durability. The coils prevent the hose from kinking and make it super easy to handle. The buoyancy of the hose allows excess to float on the surface so that it stays clear of you, the marine environment, and other divers underwater.
