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!

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 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.


Frequently Asked Questions Nemo Phase Out


The Nemo dive system is being phased out to make way for our latest product, the Nomad Mini, which is the result of design updates stemming from users feedback on Nemo and Nomad. We have combined the best features of each to bring you the sweet spot between portability and performance


Nemo and Nomad Mini are both portable, battery-powered dive systems that are similar in size. Nomad Mini has several features that set it apart, including a more user-friendly experience, increased depth rating, and ability to add multiple batteries with the DiveBoost Kit. Air flow performance of Nomad Mini is improved relative to Nemo, but in exchange it does have a shorter expected battery run time of about 35-40 minutes per battery compared to the Nemo's 60-90 minute battery run time.


Nemo batteries may be used to power Nomad Mini, under certain conditions. When using Nemo batteries (that have a date code of 2023-03-24 or older) to power Nomad Mini, you must also use the DiveBoost Kit and two fully charged Nemo batteries at the same time. One Nemo battery cannot power the Nomad Mini alone as there is a risk it will shut off suddenly while in use.

Flotation Tube and Dry Bag Float:
The Nemo Flotation Tube can be used on Nomad Mini in addition to the Dry Bag Float that comes with Nomad / Nomad Mini.

If you purchased a Backpack with a Nomad, then it will fit Nomad Mini just fine. When storing Nomad Mini with DiveBoost Kit into the Backpack, there will be a bulge in the top of the backpack but it will zip. A Nomad backpack has a height of 9 inches.
Most backpacks purchased with Nemo are the same dimensions as those that come with Nomad and Nomad Mini, however some older Nemo backpacks have a shorter height. If the height of your backpack is 7 inches, then it will fit Nomad Mini without the DiveBoost Kit but there will be a bulge from the top of the backpack. Nomad Mini with the DiveBoost Kit attached will not fit into a backpack that has a height of 7 inches.


Yes, even though Nemo is currently being phased out, we will still offer service and warranty options for our Nemo customers. If you experience any issues with your Nemo, please contact our customer service team for assistance at

    So easy. I am certified SCUBA, but it’s been years since I have donned all the gear. This thing is so simple and works as advertised. No renting tanks. No lugging heavy gear to the water. I will be using it to metal detect underwater for coins and jewelry. Good job, Blu3.

    • David

      Thank you for the positive review and feedback! We’re thrilled to hear that the Nemo has made your underwater activities more convenient and enjoyable. Don’t hesitate to reach out if you have any questions or concerns in the future. Thanks for choosing BLU3!

  2. Tom Judge

    I use the Nemo to clean the bottom of my boats that are kept in the water. It beats the heck out of holding your breath which is what I used to do! It makes an unpleasant job almost enjoyable. The only reason I give it 4 stars instead of five, is the air hose can get twisted at the point where it exits the machine causing the air supply to be blocked. I did get the protective cover for the air hose which I believe makes the issue worse. Once you get the twists out of the hose, the Nemo works flawlessly. The Nemo will save me money on frequent haul outs just to have the bottom cleaned. . An added benefit to a clean bottom and running gear is the fuel savings and performance increase. This is more important than ever with the high fuel prices we are now experiencing . I consider my Nemo a very good investment.

    • David

      Thank you for letting us know about the issue with the air hose on your Nemo, and we apologize for any inconvenience it may have caused. We have since fixed this issue on all new units and improved the hose design. We are glad to hear that you are enjoying the benefits of using the Nemo to clean the bottom of your boats and saving money on frequent haul cleaning. Thank you for choosing BLU3 and investing in our product.

  3. Stephen Patterson

    The Nemo is an excellent device for shallow-water diving. I bought one in Dec of 2021 and have put over 30 hours of dive time on it. I am an avid treasure hunter, and I use the Nemo in the beach areas of the lakes near my house. This unit is solid, and works great. If I am in a shallow beach and stay in the six or seven foot level of depth, the battery can last about an hour and a half. That is a lot of time under water!
    Another awesome part about this company is they provide the necessary online training course to prepare one for using the Nemo. It is definitely worth one’s time to complete it. It is full of important information. Great Job Blu3! I hope one day to be able to add the Nomad to my gear.

    • David

      Thank you for taking the time to leave us such a thoughtful review. We are thrilled to hear that the Nemo has been serving you well in your treasure hunting adventures. We are also happy to hear that you found our online training course to be valuable. Our team is constantly striving to provide the best customer experience, and we hope to have the opportunity to serve you again in the future. And when you’re ready to add the Nomad to your gear, we’ll be here to help!

  4. Josh Jenevein

    The Nemo is awesome. I didn’t really know what to expect because I had never used a hookah diving system before. It surpassed my expectations. Easy set up, easy to carry around, and I have 2 batteries which I have yet to run completely through both of them during a single dive. I’ve had a lot of divers talk to me about it because they love how easy and compact it is to go for a shallow dive (Nomad is on my list next). I used this for the first time in a pool to get used to it and to practice with it. I’ve now used it in the gulf on some calm days and in some springs. I’ve taken it out for about 10 dives now and I couldn’t ask for a better product. And it’s so easy to just throw on my kayak with some goggles, snorkel, fins, and weight belt and I’m good to go diving for the day. I’m so glad I purchased the Nemo because I’ve had nothing but great experiences with it!

  5. Charles White

    I purchased the BLU3 NEMO system for short shallow dives while out traveling. This system is built durable, engineered for safety and provides excellent training for first timers. If you want to get your dive on but don’t know if scuba is for you, NEMO will is the answer. I have used it to work on my pool and search for treasures in a large freshwater lake. Let NEMO take you on an adventure today!!

  6. Jesse

    I like to dive. But if you’re diving with a group you can’t stay long as you want in one place i.e. In front of a fisglh cave.
    If you’re snorkeling, you are limited to air and time underwater.
    wiht Nemo i got the freedom like snorkeling but with a feeling of diving.
    And don’t forget: there is no large heavy weight tank – it’s just a battery that you can charge as you’re charging your smartphone.
    Highly recommended!

  7. Michael Brouillette

    Have used my blu3 3 times so far and it has been great. Have primarily used for commercial pool repair and cleanings and it’s been a wonder….saved me and the customer countless hours and money. The North Carolina USA lakes are pretty brown so haven’t had a successful lake dive yet but am looking for the right opportunity. I’ve only snokeled, and this system is easy to use and a wonderful piece of equipment. I encourage newer divers/snorkelers like myself to definitely watch the great into videos. I look forward to putting my backpack on and heading to the islands soon. Great job Team Nemo.

  8. Ryan Bennett

    Amazing Product that has helped me to find countless treasures.


    Used the Nemo for the first time in Egypt this year. Loved it. Easy to set up. Easy to use. Battery lasts longer than advertised. Caused a fair bit of attention on the beach from other divers. Excellent product.

  10. Todd James

    I cannot praise my Nemo enough. The ability to carry it anywhere I want, the 5 minutes set up, and the the incredible customer service that I have received is well beyond anything I expected when I purchased it almost a year ago. I use it mostly for treasure hunting and have found multiple gold rings and other jewelry. I have three batteries and can put one on charge while using the others to get a full day without downtime. I will say the batteries last considerably longer than advertised and my Nemo is working just as well as the first day I used it after almost 100 dives. Quality like this and the customer service that comes along with it cannot be matched. Now I’m looking at the new nomad for some of those deeper spots and would gladly give my money based on my experience with the Nemo. Keep up the good work and you’ll always have a lifetime customer.
