I am a certified advanced diver with PADI, but don’t have a network of people to dive with me. I struggle with all the extra weight of tanks and the confinements of wetsuits. When I found this website, I didn’t hesitate to buy the Nomad Dive Buddy. I have had it for years and it has been amazing!! I carry it with me wherever I go. It allows me to hunt for the big shells and sharks teeth where few others can reach. The best story was about a lady that was looking for sand dollars, but she said “I’m only 5’ 2” and can’t get out far enough to reach them”. So I dove down and gathered about 20 sand dollars for her. She was so thrilled. I am constantly asked about my dive system and rave about it to anyone who will listen. Now I am ready to get the upgraded 30’ system! I can’t wait! I have had so many incredible experiences that I wouldn’t have had if I was just snorkeling. Can’t wait to take it on my trip to Hawaii!!

Bought 2 x Blu3 Nomands in March of 24 - put in about 10 hours no complaints. Regulator screws were rusting - a quick call and I had new ones, a day later. ( I winter in Florida)Used the units for another 20 hours maybe, absolutely quality kit - flawless and simple. Jump ahead to winter 2026 and two of the four batteries failed and one of the units was not operating correctly ......
One call, Jack completely understood, walked me through a bit of troubleshooting, we fixed my error - he then diagnosed the batteries and warranteed part of the replacemenet cost - thank you Jack, thank you Blue3 - the replacement batteries are expensive, you must fix this. Your customer service is 100% and your product is incredible. Thank you again from Big Pine Key. g

The BLU3 Nomad is awesome for spring river diving. It’s lightweight, easy to set up, and way more convenient than hauling full scuba gear. The airflow feels solid and it’s perfect for shallow, clear water where you just want to relax and explore. Not a replacement for deep dives, but for springs and river runs it works great and makes getting in the water quick and hassle-free.

We have been using the Nomad Blu3 unit for a little over a year. We are full time cruisers and use it about every 2-3 weeks to clean the hull of our boat. Its a game changer for our situation. We just got he 3X battery which will be even better to allow for more time cleaning. Great product!!

After using the system for 2 seasons, light use , total of 50 dives, the unit started pushing some water together with the air into the regulator. The leak was within the compressor, not the hose. I used NOMAD in that condition for 10 more dives. The unit now stopped working. The compressor is on and running but no air comes out of the regulator. Also , battery latch broke off due to vibrations. Considering this is a USA company you would expect better quality.

As I commented earlier on FB, I own one and absolutely love it. My wife and I both used it in the Bahamas and the Virgin Islands. We have been avid scuba enthusiasts for over forty years. Our BLU3 system is perfect for shallow dives as it frees us up from lugging all the required equipment related to scuba. It's the same experience as skin diving without having to surface. You hardly know it is there. We are retired and travel often so another great advantage is the compact BLU3 system is allowed as carry on when flying!

I have the Nemo model from Diveblu3 and I love it. Recently the electronic components failed due to salt water corrosion. I mailed it back to the company for them to fix it, and even though it was out of warranty, they not only covered the service charges, but also upgraded the battery and the hose attachment. They were very responsive by email throughout the whole process. What great customer service!! I highly recommend that brand!

Just starting with my nomad mini - three dives in and loving it. Really well designed, feels v stable and safe. I dive in shallow water to do u/w surveys in Greece and a tank would be really cumbersome in these conditions. This system is perfect for what I need, to be able to stay still on the seabed and measure/photograph seahorses, without stressing them out with freediving up and down constantly. Also the team in Florida are so responsive and helpful, very much recommend.

The BLU3 Nomad feels like the CPAP of diving — quiet, effortless, and incredibly reliable. Setup takes minutes, breathing is smooth and natural, and the battery easily lasts through a full hour of work under the boat. It’s the perfect mix of simplicity and performance for anyone who wants to dive without the hassle of tanks.

I recently purchased the Nomad and couldn’t be happier with it. Having done plenty of dives and snorkeling over the years, I can honestly say this combines the best of both worlds. The performance is impressive—and it’s great that the air comes at no cost! Customer service has also been outstanding. I misplaced a plug, called support, and they answered right away, were extremely helpful, and even had a replacement shipped overnight.

I went diving a week ago and had a problem with my nomad. I talked to Jack and actually shipped it out to them that day. Called and talked and said I have a big trip lined up. He said we got you.
I got my nomad delivered today. The day before I leave.
So I get to breathe under water again.

We purchased the blue3nemo dive system prior to our Atlantic crossing on our sailboat this past year, and have been impressed with the system that we have now used multiple times. It was easy to use and essential for changing anodes in remote anchorages, and made cleaning the boat bottom so much easier. The batteries have held up well, and the system has worked flawlessly. It has given us peace of mind knowing we can work to free fouled lines ourselves and take care of underwater tasks without having to find a place to haul the boat. And bonus, it’s fun to use for shallow diving!

I bought the Nomad Mini this summer and had a blast diving/floating in the rivers around Pennsylvania searching for sunk treasures & checking out underwater wildlife. We're looking forward to using it in the Caribbean during our winter warm-up, and again next summer. The device seems to be very durable, and there was a lot of thought put into the design. I was initially hesitant to spend the money before seeing the system in action, but am so glad I did! It was very easy to setup & get running. The company was quick to answer my questions as well, and seems to prioritize customer service. Thanks!

BLU3 Nomad allows you to follow underwater....from sea turtles to lobster hiding spots, all easy to access without the weight and bulk of full diving gear!

I've owned the Nemo by BLU3 for 4 years. I love this system for doing my shallow water metal detecting. It's really a perfect product for what I'm doing. BLU3's customer service has also been prompt and helpful the few times I've had question or issues. It was an investment for me to get a Nemo, but it's paid for itself many times over in finding lost jewelry/phones/watches/sunglasses, etc. for myself and others.

I have used my Nemo for years without any problems, the design is unparalleled in both ease of use and reliability. Every interaction I have ever had with the company has been five stars and they go out of their way to make sure that any small problems are taken care of immediately. Customer service like this just doesn't exist anymore and coupled with a superior product is exactly why I will forever be a loyal customer to Blu3.. there are many imitations out there but none can compare to the original. Keep up the good work Blu3!!

I have a BLU3 diving setup that I actually love. I got certified for diving back in 1970 and I've loved diving since then. What I hated was the weight and cumbersome of all of the gear. I've also used Air supply diving gear for a long time, but BLU3 is a real game changer! I can carry this along the beach and enter the water easily within moments of reaching the dive site.
I have had what I call Mr Blue - 3 . I have had no problems with this unit I got 3 yrs ago. Since then I have used it with my waterproof metal detecter Dominican Republic , 2 times and Point Mago Ca, this is so much fun. If you know someone with Mr Blue, ask to try it ! You will order right away ,have fun.

While you're limited to the length of the hose, it's a great way to explore the shallow reefs, clean the bottom of your boat, or just sit in your pool, underwater, for an extended period of time! Had to reach out to customer support regarding something basic and they were quick to respond! Highly Recommend if you're in the market. Be sure to go through the training too.. Great information.

I recently became a happy owner of a nomad! I ordered it with extra batteries and a charger. And I received another battery and charger as a gift from the blu3 team! The order was assembled and shipped as quickly as possible! Nomad was well packed and arrived in Europe without damage! Assembly was as easy and fast as possible! Immediately after assembly, Nomad proved itself in action! An excellent compact solution! I had experience using diving equipment with a dive duration of 35-45 minutes and a depth of up to 7 meters. I tried Nomad in the same conditions, with the same depth and the same dive time. And I can say with confidence - Nomad is lighter, more compact and more convenient! Only positive emotions and joy from the purchase! Many thanks to blu3!

Explore all FAQs

Before diving, read the owner’s manual, complete the Fitness to Dive Evaluation, and finish the free BLU3 Online Dive Training Course.

How does tankless diving work?

A battery-powered compressor floats on the surface and sends air down a hose. BLU3’s Smart Reg responds to your breathing, controlling when the compressor supplies air. You breathe compressed air underwater, so dive training is required.

Should I choose Nomad or Nomad Mini?

Choose Mini for the lightest setup and dives up to 15 feet. Choose Nomad for dives up to 30 feet and longer runtime on the standard battery. Both serve one diver per system.

Is Nomad just a Nomad Mini with a longer hose?

No. Nomad has a more powerful air compressor that delivers higher pressure and a higher flow rate for deeper diving. It’s paired with a larger battery and is rated to 30 feet, compared with 15 feet for Nomad Mini.

Can two people dive from one BLU3?

Nomad and Nomad Mini each support one diver. For a shared multi-diver system, explore Sea Lion from Brownie’s Third Lung, BLU3’s sister company.

Do I need training before using BLU3?

Yes. Every diver must complete the BLU3 Online Dive Training Course, read the owner’s manual, and complete the Fitness to Dive Evaluation before use. Shallow diving still involves breathing compressed air and requires proper preparation.

Do I need a weight belt and backup air?

Many divers need weight to offset natural buoyancy, especially with a wetsuit or in saltwater. Follow training to determine correct weighting. BLU3 strongly recommends a separate backup air supply such as Spare Air, along with training in its use.

Can I take BLU3 on a plane?

Travel is possible with the standard battery configurations, subject to airline approval and battery rules. Review the air travel information before booking. The Nomad 3X Battery is not airline travel friendly.
