This makes my algea dives and underwater drain replacements faster, and more profitable.... its also a blast to use in my personal time in the Florida springs!

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 flooded my nomad mini in salt water and I called for support and was advised to run fresh water through the intake system I did that and my unit is working well. Thanks Blake for your help.

Love their products. Ordered an extra battery for my Nemo and I had it in less than 24 hours. Great company to do business.

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. They truly stand behind their products and are a good example of what other companies should aspire to be. Shout out to Jack - really appreciate the support and excellence you’ve delivered.

We love our BLU3 Nomad. We use it when anchored to explore our underneath world. We put it in our dingy and take to clearer waters and reefs. My husband also uses it to clean the bottom of the boat. It is Very quiet.

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.

How Does the Nomad Mini / Nomad Tankless Diving System Work?

The main unit floats on the surface while you dive underwater. Inside of the unit there is a custom battery-powdered air compressor. The compressor pumps air to the diver through the air hose and out through our patented  Smart Reg™, which saves battery life by monitoring breathing patterns to let the compressor know exactly when it needs to send air. This means it doesn't just push air to you, but rather breathes with you.

"I was shocked at how user friendly..."

I've always wanted to scuba dive, without the scuba stuff. It all just seems intimidating. So after going over some alternatives, this seemed like the logical step. After you take the well put together online course, you're pretty much ready to hit the water. The Nomad worked amazingly on its first use! I was shocked at how user friendly the whole thing is and how comfortable I felt going out and using it. This is really a great product and I look forward to many more adventures with it!

"Great product and excellent customer service!..."

Great product and excellent customer service! I’ve used the Nomad Mini with the DiveBoost kit a few times now for my underwater metal detecting and it has been an absolute pleasure to use. It takes a bit getting used to regulating your breathing correctly but after the first time it feels natural. I would highly recommend!
