  1. 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!

  2. 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!!

  3. 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!

  4. 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.

  5. 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.

  7. 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.

  8. 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.

  9. 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!

  10. Wesley (verified owner)

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

  11. 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!!

      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.

  13. 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!

    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.

  17. 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.

    Buying this was a breeze and shipped in a very timely manner. I had taken the course months ahead of time, knowing full well I was going to own the Blu 3 Nemo. When I received it I read the manual fully and set up was as easy as everyone said it was. It has opened a whole new way to enjoy the water. Great time had every time I use it. I am going to have to but one for my wife now. Thanks for the professional service.

    Just got back from Mexico where I used Nemo many times and really enjoyed it. After being used to breathing in the pool and towards the surface it took a little getting used to breathing in deeper water as it seemed I trying to breath faster than pump was providing air. Or maybe it was pumping the same amount of air at the surface but after being compressed under water the lower volume made it feel like less air. Either way after I started breathing at the same speed as Nemo it felt very natural and more than enough air. Battery time seemed as advertised or slightly longer. Only timed my dive one time and battery lasted an hour or so. Seemed to last longer on other dives.

    I also supervised my older kids using it in the shallow pool after warning them about the dangers of compressed air and never to hold their breath. I went through one of my three batteries a day just in the pool with them using it.

    Backpack had a little extra room to carry small weights and belt and was comfortable transporting through the airport on my back. And backpack fit loosely in the airplane overhead compartment.

    Every video I watched about BLU3 NEMO,
    was Outstandingly Positive. That is why I decided to buy one. It is everything they said it was!!! Customer service is Outstanding!! Very prompt replies to any questions I had. This is Perfect for Metal Decking in rivers or shallow lakes. It sure beats my full Scuba gear for this. Almost all detecting underwater is less than 10 ft anyway. No other device on the market even come close to this product. AAAAAA++++++

  33. Gabriel Garcia (verified owner)

    I have had my eyes on the Nemo for a while after seeing Michael Oliver on youtube, it seemed like a very practical machine because of its size and weight. I have my scuba diving license and I know first hand what a pain it is to carry your diving gear down to a beach or to a unique hidden spot and I am not a fan of it. When I got the Blu3 Nemo I was not sure how good it would be. It came with a nice backpack and was pretty strait forward setting it up. I tried it in a pool first so I could get a feel for it. Then I went to my local lake and did some underwater metal detecting. It was so it easy to carry it down to the swim hole I was going to metal detect in and only took a few minutes to set up. Only difference I noticed was that I had to breath in a bit more than a regular scuba tank so I could activate air delivery system, but after a few minutes I did not even notice this, I was under water for about 35 minutes the first time and had not issues. Plenty of battery left. Look forward to using it more in the summer.

    This device is cleverly done, materials and construction are reasonable and of good quality.
    But……, even for an experienced scuba diver like I am the noise and the hammering airflow of the compressor destroys almost every fun, I think a beginner will even get scared by that.

    If I had known about that I think I would not have bought it, sorry!

    In my opinion you definitely should find and use a different type of compressor, otherwise I can’t image you will have big success with this product

    Ich habe die Full Face-Mask dazugekauft. Bei der erfolglosen Montage des Nemo-Mundstücks an die Maske bin ich in der Innenseite der Maske nur ein kleinwenig abgerutscht. Dabei ist leider das rechte Plastik-Innenteil für die Kommunikation von seinem Kleber abgegangen. Wäre es aus einem Stück gewesen, hätte es gehalten…
    Wäre e möglich, dass Ihr mir das kostenlos repariert oder eine neue schickt?
    Ich habe bislang meine alte Maske genommen und leider erst jetzt festgestellt, dass sie völlig ausreicht. Am liebsten würde ich die Maske zurückgeben…

    just a bad mark / for the charger connectors
    they are to the US standard /
    and does not work on European sockets
    (you should offer them as an option / or give a reference to buy them online)

    once this problem solved

    This device is pretty awesome. I bought since I frequently do shore dives and although the hose is 10ft, it’s more than you would expect. First time taking it out, there were 2-3 ft waves and the device seemed to hold up perfectly. I took it out for 45min and still had 1/3 battery remaining! Nemo is also very light weight and is as easy as carrying a beach chair. Customer service has also been excellent and they respond quickly. Overall I am very happy with my purchase and this product is super innovative and costs less than an iPhone.

    I am a diver that dives every day. I am mostly in marina’s and canals finding phones, wallets, keys, boat parts, glasses and anything else folks lose in the water and I retrieve them. I have a Shock Alert and underwater metal detectors and this system is awesome for a 5 minute dive to grab something in the muck. I am 63 and my tanks are getting heavy to lug around. I love this light system and it has really helped me out. I am #scubadetector on Facebook.

  57. David Cosby

    I love it! I thought that the battery would only hold a charge for an hour, but so far my record has been 1 hour and 48 minutes working under the boat and it was still pumping out plenty of air. Now I can clean the bottom of the boat in 1/5 of the time that it used to take.

  58. Jody Vining

    As someone who has used various surface supplied air systems over the decades – this thing blew me away.

    The compact, portable size makes all the difference. Not having it take up half the boat is a big deal, and opens the door to more frequent and more spontaneous dives with the rig. Also – the noise –
    Or lack thereof – is amazing. I’m not missing the sound of that gas engine whirring away constantly.

    Overall this thing is a huge win. They did an incredible job on the design. It’s obvious tons of thought went in to this product and I couldn’t be happier.

    Absolutely an incredible invention. I have not had quite enough experience yet to honestly evaluate it, but I wish I owned the patient.

    Good but no warning when the batteries die so no battery no air.

    Easy to use and very compact

    I love thats it so compact and I can pretty much take it anywhere.

    Everything worked great, my only complaint is for them to educate the purchaser that when you order two batteries that the for some reason the chargers are married to a single battery and that you cant charge multiple batteries with one charger. First time I took it out i could only use one battery as the charger would only charge one and not the other. Other than that had a great time and would recommend to others.

    First dive went awesome stayed in a small swimming hole and adjusted wet weight belt for different wet/dry suits. The Nemo seems nicely thought out and built well. The online training that was procured covered everything you need to know to use Nemo safely. The only thing I would have liked to see is a 15 to 20 foot dive depth to meet my needs better. Will definitely recommend to others. Thanks Blu3.

    Purchased two units, one of them arrived broken. The other one had bad wire connection, so water got in! Took pictures and videos of everything :-((( Then I saw a Divebuddy, which is better in every sense! All parts are better quality! Only 2 things that are better on Blu3, is the promotional videos and the nice design of the device. Customer service reacted immediately to my complaint, so let’s see the outcome. Sorry for this negative post, but I truly believe that with few upgrades, Blu3 can be a truly amazing device (just look at a Divebuddy, all the right clues are there!). Until then, I’d not recommend buying a Blu3.

    Did my first dive with Nemo this weekend. So far so good. I stayed in a small swimming hole so I could figure out how much weight I needed while wearing my dry suit, wet suit and swim suit. The Nemo seems well thought out and easy to use. Blu3 does an awesome job taking you through an online training course to prepare any level user. The only change I would like to see is the ability to go 15 to 20 feet to fit my needs better. Thanks Blu3.

    I took my Nemo out yesterday for the first time. I love it! I just did a shallow easy dive to get familiar with the gear. It worked great. Tons of fun. Handled well. No issues. Your online class is important and very well done. I highly recommend Nemo and I’m looking forward to getting back in the water this weekend! Thx Blu3, you’ve made diving fun again!

    The Nemo is fantastic. Not usually commented on in reviews, but the training course and videos are very thorough and excellent. Over 40 years ago I was teaching similar material in scuba classes. Use. When you first adjust the straps it feels a bit restrictive but in the water it is perfect. I would recommend the straps be a bit longer. As I am a big guy they were almost too small. When you first try it out you feel the pump supply the air with a brrrrrrrrr sound. But you get used to that quickly and in the marina it is not noticeable at all with all the other sounds around. The air supply is very smooth and enjoyable. I used Nemo when I was cleaning the propeller on my sail boat. I bought Nemo basically for that purpose, instead of gearing up with scuba to clean the propeller off of barnacles and mussels. It surpassed my expectations. I will get the protective cover as I can see a need for it after my first outing with Nemo cleaning the propeller. What a great device. It has been a while since I have been this excited about anything I’ve bought. My wife was impressed with my comments. The battery lasts longer than I expected based the rated time limit. As one of the other reviewer commented, after one use I would definitely buy it again. And I am considering a second for my wife and son. By the way I am 66.

    The Nemo is absolutely amazing! I’ve been looking at dive hookah systems for a while now. The gas powered options are expensive and bulky and other battery powered models I’ve looked at have some other draw backs. The Nemo checks all the boxes for me and I’m very impressed with this little system. I use mine for metal detecting in the deep trough at my local beaches. I wasn’t sure if 10′ feet was really going to be deep enough to get down to the bottom but, it was even at high tide. Talk about looks at the beach, people that have never seen anything like this watch in wonder as Nemo floats by. Only to be surprised as I surface to get my barring before diving back down. So what’s it like using Nemo? On the inhale you can hear Nemo’s compressor run. It sounds like a little machine gun or maybe the government printing press printing out those stimulus checks…brrrrrrrrr. While inhaling you can feel the air supply having a pulsation feeling as the compressor runs. The stated battery run time from my experience is not limited to 1 hour. I was getting 1 hour 45 minutes on a single battery. From my understanding a scuba tank lasts about 1 hour and a little longer if you control your breathing in comparison. Nemo bridges the gap between snorkeling and scuba. Now that I’ve used my Nemo would I buy it again if I had to do it all over again? Yes, I would and I’m going to be buying my wife one in the near future as well.

    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

    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.

    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.

    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.

    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.

    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
