The Smart Reg™

What allows Nemo to be so compact, energy-efficient, and responsive is our patented 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 a fraction of 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.”

Nemo’s flotation foam gives the unit inherent buoyancy, just enough to float without the flotation tube added on, so you’ll never have to worry about the unit sinking. But always use the flotation tube for times when additional buoyancy, stability, and visibility are desired! (anywhere outside of the pool)


The Battery Pack

Nemo is powered by a custom lithium-ion battery pack that is swappable and rechargeable. The pack and connector are IP67-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!

Dry Bag Float

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 3 to 4 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.

BLU3 Backpack

Take Nemo with you to new dive spots around the world with the BLU3 Backpack, designed specifically to make carrying Nemo and the rest of your gear as easy as possible.

    Super awesome product. Only one thing i had to work loose was the connector to the battery on the unit itself. Ran into my shipment being lost and contacted Nemo and i got my product in 3 days. I have to thank David for that awesome customer service.
    I would recommend this product to anyone that wants to have the best hooka dive system out there!

    Thank you Blu3 Nemo.

      Hello Francesc,
      Thank you for the 5 star rating.

  7. Anonymous (verified owner)

    Works as advertised super convincing and easy to use. Highly recommend price could be lower but I understand this in new tech so you have to pay.

    • BLU3

      We are so grateful for your 5-star review. Thanks for sharing your rating with us and the community. We do offer financing through PayPal or Affirm.

  8. Welsh Tucker (verified owner)

    This device is pretty awesome. I bought since I frequently do shore dives and although the hose is 10ft, it’s more than you would expect. First time taking it out, there were 2-3 ft waves and the device seemed to hold up perfectly. I took it out for 45min and still had 1/3 battery remaining! Nemo is also very light weight and is as easy as carrying a beach chair. Customer service has also been excellent and they respond quickly. Overall I am very happy with my purchase and this product is super innovative and costs less than an iPhone. Check out my Instagram as I will also be adding more underwater videos using the Blu3 Nemo: @welshtucker

      Hi Welsh,
      Thank you so much for this great 5-star review. We really appreciate your business and helping to share the word about Nemo.

  9. Robert (verified owner)

    I am a diver that dives every day. I am mostly in marina’s and canals finding phones, wallets, keys, boat parts, glasses and anything else folks lose in the water and I retrieve them. I have a Shock Alert and underwater metal detectors and this system is awesome for a 5 minute dive to grab something in the muck. I am 63 and my tanks are getting heavy to lug around. I love this light system and it has really helped me out. I am #scubadetector on Facebook.

  10. David Cosby

    I love it! I thought that the battery would only hold a charge for an hour, but so far my record has been 1 hour and 48 minutes working under the boat and it was still pumping out plenty of air. Now I can clean the bottom of the boat in 1/5 of the time that it used to take.
