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.

The Nemo Dive System

Nomad 30FT

"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!

Nomad Mini 15FT

"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!

The Nemo Dive System

Nemo 10FT

"...it only took a few minutes to setup!"

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 straight forward setting it up. I tried it in a pool first so I could get a feel for it. Then I went tot 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 underwater for about 35 minutes the first time and how not issues. Plenty of battery left. Look forward to using it more in the summer.
