The details.
What comes with Nomad?
Nomad with Smart Reg and 40-foot hose, a standard battery and charger, BLU3 Backpack, Dry Bag Float, red dive flag and access to the online training course.
Extra batteries, additional chargers, Alpha flag, Flotation Tube, Spare Air, OTS Spectrum and PulseDive are sold separately. Select your battery and charger options at the top of this page.
How do the battery, compressor and hose work?
The rechargeable 144 Wh lithium-ion battery has a charge-level indicator. The battery and connector are IP67-rated; standard charging takes approximately 3 hours. Low-battery pulsation behavior is covered in the required training.
Inside the Smart Reg, a silicone diaphragm moves as you inhale. A waterproofed sensor signals the custom compressor to match air delivery to your breath. Corrosion-resistant components are designed for marine use.
The 40-foot coiled hose balances flexibility, durability and easy storage. Its extra length provides towing scope; maximum diving depth remains 30 feet.
How can I extend my dive time?
Swap in a spare standard battery for another 45–60 minutes of typical runtime, or choose the optional Nomad 3X Battery for three times the capacity and up to 3 hours of runtime. Runtime depends on depth and breathing rate. The 3X Battery is not airline travel friendly.
Can I add Spare Air or other accessories?
BLU3 strongly recommends Spare Air as a reserve air supply. Learn to use it before diving. Dive weights, flags, flotation accessories and replacement parts are also available.

Does Nomad float on its own?
Yes. The EVA foam provides inherent buoyancy. Use the included Dry Bag Float or optional Flotation Tube for added buoyancy, stability and visibility, particularly offshore.
Nomad must be in water during use to stay cool. Never operate it out of water.
Can I use Nomad for hull cleaning and boat inspections?
Yes. Nomad is suitable for hull cleaning, propeller inspections and other underwater boat maintenance within its 30-foot depth limit and your training. Its compact size also makes it easy to store aboard for day trips or longer voyages.
How do I care for Nomad after saltwater use?
Nomad is designed for saltwater environments. After use, thoroughly soak it in fresh water and follow the cleaning and maintenance procedures in the owner’s manual. The proprietary compressor is designed to tolerate accidental saltwater intrusion; follow the manual’s freshwater flushing procedure if this occurs.
What if Nomad flips or goes underwater?
The intake snorkel’s top must remain above the surface to draw fresh air. The rest of the unit can be submerged, but a submerged intake can interrupt air delivery. Follow the training and owner’s manual procedures for interrupted air supply. If water enters the pump, follow the prescribed freshwater flushing procedure.
Can I fly with Nomad?
The backpack is sized for carry-on travel, but baggage allowances vary. The standard 144 Wh battery must travel in carry-on baggage and requires airline approval. Confirm requirements with your airline before travel. You may check the system while carrying the battery separately. The Nomad 3X Battery is not airline travel friendly.
Does the battery last longer in shallow water?
Shallower dives typically use less power and can offer longer runtime. Depth and breathing rate affect battery life. Excess hose can be coiled neatly as described in the manual so the unit stays closer during shallow-water use.
Who can use Nomad?
All users must read and understand the Nomad Owner’s Manual, complete the BLU3 Fitness to Dive Evaluation, and complete the BLU3 Online Dive Training Course. Users must be able to swim 200 yards without stopping, with no time limit, and tread water continuously for 10 minutes.
Users ages 8–9 are restricted to swimming pools, in water shallow enough to stand with their head above the surface. Users must be at least 10 to dive outside a pool. Users under 18 require parental or guardian supervision at all times. Always follow the current owner’s manual and training requirements.
Magnet warning: Nomad uses strong magnets that may interfere with pacemakers or medical implants. People with pacemakers or medical implants are advised not to use Nomad and must remain at least 2 feet from its main body at all times.
What warranty and support are available?
Nomad includes a one-year limited warranty. Extended warranties are available separately. For product registration, service, troubleshooting and replacement parts, visit BLU3 Support or email info@diveblu3.com.
What about international shipping?
For orders outside the United States, the buyer is responsible for customs and duty fees charged by the destination country.

Great product, fast shipping! Very happy!
MARK DAVIS –
I couldn’t be happier with you customer service. I ordered my Nomad during the 20% off sale and it arrived missing the 2nd battery without question I was sent the battery overnight. So far I have only used Nomad in my pool but I can’t wait to try in the ocean.

Great reliable setup for searching for underwater treasure. Provides plenty of air and is very travel friendly. Other competing systems I have looked into are taking air in from the same compartment as the battery and if they even ingest water they will shut down with most likely Permanent pump/battery damage. Definitely not safe when your life is on the line. Blu3s batteries are separate and under the unit. The pumps are custom made to handle water and will pump the water out without damage. Battery swaps take seconds and with Blu3 being made, shipped, and serviced in the USA its a no brainer. Blu3 and Brownies (building dive systems for 45 years) work hand and hand with each other so you know you are getting the best.

The Nomad for me has been a game changer. I dive for treasure on local beaches here in Finland and the possibility to dive for easily over an hour and just swap batteries within a few seconds and back to an other hour of diving is AMAZING!

Overall great product. I use it to spearfish lakes in Arkansas because most of our fish are less than 20 feet deep. Mostly brush piles and rocks. I was afraid the noise would scare the fish but from the 8ish times I’ve taken it out, I think it helps peak their curiosity for a little bit. It’s definitely helped me become more efficient at spearfishing so I can sit on moss beds much longer and be more patient instead of rushing a bad shot. On complaint is it definitely tilts in the water towards the battery side but still floats well enough it’s not a problem.
David –
Thank you for taking the time to leave a review! We’re thrilled to hear that the Nomad has helped you become more efficient at spearfishing and allowed you to be more patient while waiting for the perfect shot. We’re also happy to inform you that we’ve addressed the tilting issue you experienced and have fixed the product accordingly. We appreciate your feedback and hope that you continue to enjoy using the Nemo on your future spearfishing trips.

I recently purchased the Nomad just before Our trip to the Florida Keys from North Florida. I actually stopped by the shop to pick it up thanks to all the coordinating efforts of Seairra, thank you so much! We love the Nemo, and already enjoy the Nomad that much more. It’s a quality product that just easily enhances the time we spend on the water with the freedom of no tanks!
David –

We hope you continue to have great experiences with our products on your future adventures.

Love my Nomad. I get nearly 60 mins. on the bottom but no heavy tank!! At my age (62) I wanted something mobile, and lightweight, that was simple and easy to get to the bottom. The Nomad does not dissapoint! It works like a charm. Thank you Blu3 team for designing and delivering such an exceptional product.
