About Nemo

Nemo is a compact dive system that supports 1 diver to 10 feet with a rechargeable battery pack that lasts over an hour. Air is drawn from the surface above the water and pumped through the air hose to deliver clean breathing air to a diver up to 10 feet deep.

Nemo’s custom-designed compressor is fully sealed and built to interact with saltwater. Patent pending Smart Reg™ technology enables Nemo to be the world’s smallest dive system and weigh in at only about 10 pounds.

Battery Powered

Nemo’s lithium ion battery weighs about 1.3 pounds and can be easily swapped for an additional 60+ minutes of run time. Recharge time is 3 hours or less. The battery capacity is less than 100 Wh (watt-hours) so it can be brought onto an airplane in carry-on luggage.

Patent Pending Smart Reg™

Nemo’s Smart Reg is patent pending and unlike any other diving regulator on the market, and it is what enables Nemo to be more portable and energy efficient than any other dive system on the market. Inside of the Smart Reg, a waterproofed sensor detects when a diver inhales and 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.

Nemo Online Dive Training Course

Learn about diving techniques before Nemo Diving by taking the Nemo Online Dive Training Course, available for free to anyone at any time at This course was specifically designed for Nemo Diving with the help of experts in the field of diving. It is required that all users complete the course with a passing score prior to Nemo Diving.

Dive Flags

Dive flags are used to signal that a diver is underwater. The Red and White flag is used in the United States, Canada, and some other countries. The Alpha flag is used in most other countries around the world.

Always check the dive flag regulations for where you’ll be Nemo Diving and make sure to install the proper flag style so that boating traffic will steer clear while you are underwater. If you travel, you may find it useful to have one of each – choose “Both Dive Flags” from the drop down menu above!

Flotation Tube

Nemo has enough buoyancy to float in the water without clipping on the flotation tube for times when you are diving in the pool or other enclosed body of water. But whenever waves or boating traffic are present in your diving location then the flotation tube should be installed to provide Nemo not only 22 lb of additional buoyancy but also superb visibility.

The flotation tube easily inflates and deflates so that it packs away nice and small. Inflates by oral inflation. To attach the flotation tube, simply slide it onto Nemo from the top and clip the corresponding buckles together.

Nemo Backpack

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. Includes pockets for your flotation tube and dive flag. Nylon blanket unfolds to give you a mat while setting up for your dive.

OTS Spectrum Full Face Mask

The OTS Spectrum is a Full Face Mask that can be used with Nemo to eliminate the bite down mouthpiece of the Nemo Smart Reg. The Spectrum adapts to the Smart Reg by inserting the Smart Reg into the Spectrum and securing with a zip tie. With the Spectrum, users can breathe through their mouth or nose, with no need to bite down on the mouthpiece. The mask seals around the user’s face for extreme comfort and warmth.

Other benefits of the Spectrum Full Face Mask: no jaw fatigue, no dry mouth, double seal for a better fit, five point head harness and the option for communications systems. Add on the Spectrum GoPro Mount if you have a GoPro you’ll use to film your dives with Nemo.

    G,day BLU3 ?
    I’ve used a variety of hookah systems and have to say NEMO has been Alot of fun due to its light weight compact travel friendly design and almost silent system allows me to take NEMO anywhere. NEMO has already helped me reunite 3 people with their lost wedding rings. Your welcome to see me diving with NEMO on my YouTube channel: Michael Oliver. Overall I’m happy with my purchase and gave 4 stars, I’ll give 5 stars for a 10 metre hookah I hope to see BLU3 Roll out in the future. See you on the next hunt

    I bought NEMO so I could dive under my boat in the Mediterranean. I had SCUBA kit but found it difficult to get bottles refilled. Then my air cylinder needed to be pressure tested and that proved almost impossible. NEMO is the perfect solution for me. I only need to dive to 2 metres to clean the hull and change anodes. So far I have only used NEMO in a swimming pool. I am looking forward to using it later this year when I take it out to my boat in Greece.

    I originally purchased my nemo dive device during their kickstarter campaign. Since the beginning I have been more than impressed with the company and their team. They had consistently kept backers updated about their product and once it came time to ship boy did Nemo impress. The device far exceeded my expectations, and worked better than I expected. The nemo device is simple to use, with dive times lasting well over an hour. I am very thankful I purchased their buddy pack as it has been extremely fun to dive with friends. These devices are very compact, lightweight, and easy to travel with. I fit both of mine in a carry on bag and transported them on the plane with ease. My first few dives with Nemo absolutely blew my expectations out of the water. I cannot wait to see what team Blu3 has instore in the future. After diving with Nemo vacationing will never be same so many endless possibilities. I cannot wait to share my experience with friends and family in the coming summer months. I highly recommend the nemo device if you are interested in learning to dive or already enjoy diving.

    Blu3 Nemo has been incredibly valuable in search and recovery of aquatic treasure & lost items. My friends and I have Blu3 Nemos that we use for uncovering prehistoric fossils in central florida. We have found Mammoth bones and Megalodon Shark teeth thanks to Nemo. Nemo is way easier to use than tank based scuba gear and much lighter weight. That has prove very useful in remote areas where we dive. What I love about Nemo is I’m not being dependent on dive shops to fill tanks. Battery lasts at least an hour in my tests even with some newer divers. I simply can charge my batteries at home and go out diving whenever I want! The unit is so compact I even can carry it in kayaks and paddle boards. Excellent rig for Lobstering in the Florida Keys or Bahamas. Also a great rig for teaching kids diving skill basics in the pool. I like that the pump can only be turned on/off by the diver. This unit was designed with safety and quality in mind & it shows. Excellent product for the money and will likely buy more from this company.

    Nemo has been a hit with me, my family and all who have tried it so far. I bought several units to try for a family vacation. This summer. We have so far taken then to a 12′ indoor pool. The aquatics director tried it and loved it, we brought a freind who has never been to the ocean, or snorkled or scuba’d. He watch the very well designed training and we then hooked him up. He jumped in a stayed under for over 40 minutes in one session, playing with my kids. I am a big guy and blow thru a tank scuba diving in 25min. I was able to swim at the bottom of the pool ( with weights) for an hour chasing after coins and pool dive toys with my kids and freind. My wife likes the carry bags, as it holds battery, mask, weight belt, camera, dive socks, suntan lotion ,and you have cool outside straps for fins. We found we can pack two nemos and stuff in 1 x carry on so now we have 1 set aside as as our go bag for trips. We are awaiting to go to the caymans to explore the ocean. Oh btw they are quiet in a pool. With every one else talking and outside noise, the little back ground sound from each unit is not noticed. I just recently took to outdoor pool at out condo in fl with a bunch of seniors. No one complained about noise, and all want to borrow the 2 units I am now keeping in my condo for their kids to play with.

    I have only used the NEMO in the swimming pool at the YMCA to familiarize myself with it, and it functions perfectly. I then booked a vacation to St. Thomas/St. John, specifically to use the NEMO for shallow water reef diving, but I never made it there. Tornados and a severe weather system shut down the southeast US, stranding me in the Charlotte airport. As it turned out, they couldn’t get me to St. Thomas, and they turned around and flew me back to Pittsburgh. I didn’t get to dive with the NEMO, but I had a lot of experience carrying the unit around the airport for 14 hours. As such, I can offer some advice about traveling with it.
    Rather than lug it around in its backpack (after 14 hours, it would have become a load), I purchased an iFLY 18-inch Upright – Fibertech Kids suitcase from Walmart ( It makes the perfect travel case for the NEMO. The unit fits snuggly into it, and the case is small enough to fit under the seat of your standard airline seat. With the wheels and the telescoping handle, it’s perfect for air travel. I keep the inflatable ring, charging cord, and my neoprene weight belt (without the weights) in the storage side of the case. The snorkel is a little too long to fit, so I pack that in my larger checked suitcase along with the weights, mask, fins, and NEMO backpack. (I’ll use the backpack when transporting the unit to the dive site.)
    To secure the unit inside the suitcase so it doesn’t slide around, and so you can sit the case on any side without the unit moving around inside, I installed a web strap with a clip that I pass around the metal tubes lining one side of the suitcase, the tubes through which the retractable handle slides. Using this strap, I can securely fix the unit inside the case, tying it to the metal tubes. (Installing the strap requires cutting two slits in the lining. I applied duct tape to the lining first before cutting the slits to keep the material from fraying.) I also inserted a small piece of foam padding at the end where the NEMO rests against the suitcase and on the other end to keep it from sliding forward. The harness, regulator, and air hose, I coil inside the suitcase beside the unit.
    Since the lithium battery is installed in the unit, you could put the NEMO in your checked bag (or check this small kid-sized bag), but the TSA is going to open the bag and take a look at the unit. They will also pull it out and inspect it, swabbing it for explosive residue. I prefer to be there with them when they do this so I can be sure it is strapped in properly when they are finished; therefore, I take it as a carry-on through the TSA checkpoint. It didn’t take them long to do their inspection, and I even alerted them about it when I placed it on the belt. Regardless of whether you say anything or not, they are going to open the bag once it passes through the X-ray machine because, let’s face it, it looks like a bomb in the suitcase! After you get it through the TSA checkpoint, you can always gate-check it if you don’t want to carry it. They forced me to gate-check it on my return flight to Pittsburgh, even though it is tiny and fits under the seat, but I was too tired to argue with them after 14 hours in the airport. I also feel better carrying the unit with me rather than trusting the airline people to be gentle with it as a checked bag. After all, it needs to be functioning properly to deliver air to me when I’m submerged.
    I’ll be taking a cruise in April that will stop in Grand Cayman and Cozumel, so I will get to use the NEMO at Eden Rock and Devil’s Grotto on Cayman and another spot I’m familiar with in Cozumel.
    I’ve posted pictures of the NEMO inside the suitcase at
