Time is valuable. Nemo is hassle-free and easy to use. Spend more time underwater and less time filling tanks. Charge your battery and get out there!

Durability is key. Nemo's proprietary air pump withstands saltwater intrusion without damage. All of Nemo's parts are corrosion resistant and simple to maintain.

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

  1. Mike Brady (verified owner)

    I’m completely enamored and in my second season with my NEMO. As a”young-ish” 60 year old, my wreck diving days are behind me. I’m out in the bays & beaches everychance I get. Cleaning up trash, treasure hunting and just generally enjoying the underwater environment as I always had….but so much more conveniently. I spent the pandemic watching Michael Oliver doing wonderful work as a steward of his local ecosystem and I WAS HOOKED. Can’t wait to get back out this week.

  2. Jeff W

    I purchased the Nemo set up to clean my swimming pool. It’s a whole lot more fun blowing bubbles while cleaning than standing on the deck! It’s a fantastic set up. I bought 2 batteries so I can spend a good amount of time under. I have also taken the opportunity to involve my daughter in diving concepts for future fun in the islands! I have had no issues with the system. The Nemo is great set up! Recommended!

  3. Wesley (verified owner)

    Great product.
    And alot of fun on vacation or with metal detection.

  4. Zach

    Amazing product and the best customer service I’ve ever experienced!! I ordered my Nemo and got the wrong plug. So, I shot the team at blu3 an email and within hours I had a shipping number for the correct plug. I am extremely satisfied. Also, I would 100% recommend this for anyone who loves to scuba/ snorkel. It’s the perfect bridge between a scuba dive and a snorkeling session. The unit pulls air very easily and naturally. It also has a quick and easy set up. Great job to the team at blue!!

    • Emily Smith

      Hey Zach. Thank you for taking the time to leave us a review. It’s great to know that you’re loving Nemo so far! Thank you again for contacting us about the plug. Mistakes don’t happen often but when they do, we appreciate customers coming to us and allowing us to rectify the issue. Your glowing remarks regarding our service made our day. Thanks again, and have a wonderful rest of your week.
      Happy diving.

    Aloha Blu3 ohana,
    Love my Blu3 Nemo. So stoked to get to the next level under the sea finding treasures, recoveries and reef cleanup. After the quick customer service you’ve provided and have helped me out with, Blu3 has my 100% support and I proudly recommend this to everyone who ask me about what it is???? Mea aloha, Patrick

    • Emily Smith

      Aloha, Patrick! Thank you for taking the time to leave us a review. At BLU3, we strive to provide amazing customers like you with the best service so we thank you for noticing. Nemo can be used as a tool and a toy, so you’ll definitely be getting your use out of it! And It sounds like there’s a lot of fun to be had.
      Happy diving!

  6. Damon Jacobs (verified owner)

    This is an amazing unit for our underwater relic recovery team! We only have one certified SCUBA diver on the team, so this unit will be able to aid us with doing shallow water dives without having to get more members certified for SCUBA! Thank you so much BLU3 for the user friendly and simple user guides and certification course.

    • Emily Smith

      Hi Damon. Thanks for leaving us a review! It’s great to hear that you and your relic recovery team are enjoying your Nemos. Nemo is perfect for shallow dives and was intended to give water enthusiasts – like you – a substitute for scuba diving. It’s also awesome to know that you appreciated the free online training course and the Nemo Owner’s – Users Manual. We always encourage our BLU3 divers to complete the course and review the manual before their first dive on Nemo or Nomad.

      We hope you have a great day!
      -BLU3 Team

  7. Tim wah

    Definitely the future of scuba divig. I like the fact I only have to wear a weight belt and I’m not constricted as you are with a scuba BC. It’s definitely an awesome machine and highly suggest getting one.

    • Emily Smith

      Hi Tim! Thanks for the review. We are glad to hear that you’re enjoying your Nemo. Have a great day.

  8. Tae Hoon Kwon (verified owner)

    I ordered from South Korea for underwater metal detection. It’s a really good product. This portable system relieves stress on heavy scuba diving equipment. Please refer to the video below for my review:)

    • Emily Smith

      Hi Tae! It’s great to hear that you’re using Nemo for metal detecting. Thanks for taking the time out to link your awesome video too. Have a great day! -BLU3 Team

  9. Charles P. (verified owner)

    Have only used it a couple of times, but it is just right for what I purchased it for. I have a man-made pond in our back yard (about 7 feet deep at its deepest) and I wanted something that would allow me to stay under water while I clean the pond liner. Had to buy a weight belt so I could stay near the bottom easier as I scrubbed the liner. Very happy with the purchase so far.

    • Emily Smith

      “Hey Charles. How cool! It’s great to hear that you’re happy with the purchase. Nemo is great for underwater maintenance. Thanks for buying BLU3!” -BLU3 Team

  10. Seth (verified owner)

    I’ve been considering this purchase for about 1.5 years. I’ve watched many videos on this product, and similar products and recently decided on the Nemo for my situation. It is everything I expected. Excellent design and
    engineering from the product, to the backpack, and even shipping methods. This is one well thought out product. I spent almost an hour in the water this weekend. Buyers should plan to spend a 4-6 hours going through the online training program, practicing assembly at home, and finding a pool to practice basic diving skills. You will be pleased you spent the time getting to know the product once to get into open waters.
