How Does a BLU3 Dive System for Pool Leak Detection Work?

Instead of carrying heavy scuba tanks that require refills, BLU3 systems deliver air from the surface through a small floating compressor. The compressor sits on top of the water, powered by a rechargeable battery, while you breathe underwater through our patented Smart Reg™ regulator. This Smart Reg system enables Nomad Mini to be less than half the weight of the nearest comparable products, making BLU3 dive systems the only truly ultra-portable systems on the market.

It’s a lightweight, portable system designed for use in shallow water — perfect for pool leak detection and repairs.

A person uses BLU3 Nomad Mini to breathe underwater in a swimming pool without scuba gear.

Why is Nomad Mini the Best Dive System for Pool Leak Detection and Repairs?

For pool service professionals, efficiency and reliability matter most. Traditional scuba gear is heavy, costly, and time-consuming to manage, while snorkeling or breath-holding limits how well you can inspect and repair. Nomad Mini is the best dive system for pool leak detection because it’s lightweight, portable, and designed by the Brownie's Third Lung team in South Florida. Our included BLU3 Online Dive Training Course can even be taken before purchase, so you and your team can get trained and ready to work with confidence.

When you buy direct from BLU3, you’re working with the manufacturer behind Brownie’s Third Lung, a trusted name in surface-supplied diving since 1969. Unlike cheap, unserviceable imports, BLU3 systems are engineered in South Florida with professional-grade components, backed by real support and warranty coverage. That’s why pool pros who invest in Nomad Mini save time, reduce overhead, and build trust with their clients.

Compare Nomad vs Nomad Mini — Which Dive System Fits Your Work and Lifestyle?

Nomad Mini is the ideal dive system for pool leak detection and repairs, but BLU3 also offers the Nomad — designed for deeper dives up to 30 feet. Many pool professionals choose Nomad Mini for day-to-day service work and then consider Nomad for recreational diving, boat maintenance, or exploring underwater beyond pool projects. Both systems share the same professional-grade engineering, warranty, and training access — the choice comes down to your specific needs.

No matter which system you choose, both include a backpack, easy-swap batteries and airplane-friendly design. Plus BLU3’s training and warranty support!

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 am so happy that I bought from you a whole year's experience of diving under the sea, very fun, a special device. I just saw that you released a new battery that lasts two hours, what is its price?

We knew we needed a BLU3 when we purchased our catamaran. This device is a game changer not only for boat bottom maintenance but exploring. We put it to the test, helping a fellow sailor unsnag their anchor. Hands down an amazing tool. Thanks Blake and team for an out of this world product.

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.

Ok I love my nomad. I have used it at many beaches in Florida to the Caribbean. But what has made me like them even more is customer service.
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.

The Blu3 Dive system has been exceptionally helpful for the work on our Coral City Camera and urban coral research. It gives me more flexibility to do work underwater in relatively shallow water where I would normally have to hold my breath via snorkel

21:37 09 Oct 25

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!

18:00 09 Oct 25

Having used a Nemo for several years, my friends and I decided to upgrade to the Nomad Mini. Easier to use, and better for cleaning sailboats, as 5 feet makes a material difference. I cannot say enough good things about the product support, and development.

I purchased the 30 foot model of the Blue Sea and have used it for bottom cleaning on my 53 foot mono hull with a 6 foot draft. It has exceeded my expectations! The fast charging time of the battery packs and the 30 foot air hose fits the bill.

I bloody love Blu3! I own a boat and it is brilliant for diving under the boat to remove ropes (oops) around the prop and check the intakes. And then you can chase after fish. fabulous

These guys make outstanding products and their customer service is second to none. My kids have were certified to dive, but wanted to do it more often with a lower barrier to just "check a spot out". The Blu3 Nomad is the perfect tool for this and these guys make a first class product with outstanding after sale service.

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!

I am so happy with our purchase! I relinquished my heavy/awkward SCUBA gear years ago...and am so happy to have found the ease and convenience of the Nomad underwater discovery device!

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 felt very comfortable and at ease using BLU3. Customer service is exceptional, Jack was very helpful in keeping my unit in perfect running condition!

Highly recommend

An out-of-this-world experience!
BLU3's equipment is unlike anything I’ve ever used before! innovative, lightweight, and absolutely game-changing. Whether you're a beginner or experienced diver, their gear opens up a whole new way to explore underwater. The team at the store is incredibly kind, welcoming, and truly know their stuff. They answered all my questions with patience and gave me great advice. I only have amazing memories from this place, thank you BLU3!! for such an unforgettable experience! Highly recommend to anyone even remotely curious about diving. 🌊💙

16:34 22 Jul 25

We absolutely love our BLU3 Nomad! We keep ours on our boat when traveling, using it to dive and maintain our hull /zines as well as spearfishing and Lobster hunting. It is compact, self contained and lightweight, making it easy to take with us when exploring in our dinghy. No affiliation with the company, just a very satisfied customer. Bonus is that it is easy to reach support at their company, speak with a knowledgeable person and get answers with any questions. Highly recommend!!!!

Met Heather, Blake, and the guys at Blu3 today! I’ve had my Nomad for about a year and it has been amazing. Great team and so willing to help in any way. I lost a few minor items and they had me replacements and a minor issue fixed for me in minutes!

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.

Jeff R.

02:09 31 May 25

The Nomad is a great product. I use it mostly, but not totally, in less than 5' of water. At these shallow depths I get about 1 1/2 hours of battery power. I've had it over two years. Customer service is fast, friendly, and helpful.

Sergei M.

21:38 12 May 25

Working with the Blu3 dive systems has been a breeze! Many people may know me from my videos but few know I only use Blu3 made systems for my treasure hunting. I highly Recommend their products to anyone looking for a hookah diving system for whatever they need it for, treasure hunting, Spear fishing, boat maintenance, or just simply diving to have fun. The dive systems are easy to use, easy to maintain, portable and safe. Everything I could have asked for in a dive kit and more!

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.

19:28 23 Apr 25

We already have a Nomad Mini, and love it, so we decided to purchase a second unit! 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 saw the BLU3 Nomad at a boat show and thought it was the coolest idea ever. I rationalized that I would use it to clean our bottom when cruising but the truth is that I just wanted it. I ordered and using the Nomad was even more fun than I expected. I love how compact it is, and how easy it is to use and maintain. Best boat purchase of the season!

Great company, great staff. Incredible customer service. We love our Blu3 products and excited for all the new technology this company brings to the industry.

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!

I purchased my Nemo from Blu3 over a year and a half ago, and I’ve absolutely been loving it! Their support team is great, as they always respond to my emails promptly and address any questions I have with the care and concern you would expect from a professional and reputable company. They have 10 out of 10 for products and customer service in my book.

Frequently Asked Questions About Using BLU3 Dive Systems for Pool Service

We get a lot of questions from pool professionals about how BLU3 dive systems work for leak detection and repairs. Here are answers to some of the most common ones. For more details, check out our full FAQ page.

What Training Is Required to Use a BLU3 Dive System?

Every BLU3 system includes our Online Dive Training Course, which your team can take before purchase. The course is comprehensive with quizzes and tutorial videos that show users how to perform necessary skills for diving with BLU3 dive systems.

Do I Need Scuba Certification to Use Nomad Mini?

Scuba certification is always recommended for diving with compressed air. All users of BLU3 dive systems, whether scuba certified or not, need to complete the BLU3 Online Dive Training Course, available at diveblu3.com/training. Certain health and fitness requirements still apply.

Can You Recharge a BLU3 Underwater Breathing Device In a Car or Boat?

Yes, with an inverter, it's possible to charge our underwater breathing devices from a DC source. We recommend using an inverter with a power rating of 100 W or more for either device.

How Does a Diver Know When Nomad / Nomad Mini Battery Is Depleted?

As the Nomad's / Nomad Mini's battery gets closer to complete depletion, it begins to sputter with slight delays in airflow in the middle of each breath. These minor delays will cause a pulsating sensation that will be noticeably different from normal airflow. These are the signals to conclude the dive and start your ascent.

Why Buy Direct From BLU3 Instead of Cheaper Products Online?

BLU3 is built by the team behind Brownie’s Third Lung, trusted since 1969. We engineer and assemble our systems in South Florida, provide real warranty support, and include training. Cheap knockoffs may look similar but are misleading in their specifications, and they are heavier, unreliable, and lack real customer service.
