What Is a Hookah Diving System?
A hookah diving system is a type of surface-supplied diving setup that delivers breathing air to a diver through a hose connected to an air source at the surface. Instead of carrying a scuba tank on the diver’s back, the air supply stays above the water.
Traditional diving hookah systems are often used for shallow-water work, boat maintenance, hull cleaning, lobstering, dock work, and recreational diving. Some systems use gas-powered compressors, some use electric or battery-powered compressors, and some are designed for multiple divers.
Brownie’s Third Lung systems are one of the best-known names in this category and remain an excellent option for divers who want extended runtime, multi-diver capability, and a more robust floating surface-supplied air system.
Hookah Diving System vs BLU3
BLU3 systems are also surface-supplied, but they were designed around a different goal: making shallow-water diving as portable, quiet, and simple as possible.
Instead of a larger traditional hookah setup, BLU3 Nomad and Nomad Mini use compact battery-powered floating surface air systems. This makes them especially useful for travel, sailboats, paddleboards, small boats, underwater photography, pool service, boat maintenance, and quick shallow-water dives.
The right choice depends on the use case. Brownie’s Third Lung systems are excellent when you want longer multi-diver sessions and more capacity. BLU3 is ideal when portability, battery power, fast setup, and lightweight travel convenience matter most.
A Portable Modern Take on Surface-Supplied Diving
Many divers searching for a portable hookah diving system are really looking for a way to breathe underwater without hauling scuba tanks, managing refills, or carrying a large setup.
BLU3 fills that role with compact battery-powered systems designed for shallow-water diving and personal ownership.

Comparing traditional hookah diving systems, Brownie’s Third Lung systems, and BLU3 tankless dive systems across the categories that matter most to divers.
| Feature | Traditional Hookah Diving System | Brownie’s Third Lung | BLU3 Nomad / Mini |
|---|---|---|---|
| Air Source | Surface-supplied air from compressor or surface unit | Floating surface-supplied air system with gas and battery-powered Sea Lion options | Battery-powered floating surface air system |
| Best For | Shallow-water work, dock use, boat cleaning, and longer surface-supplied dives | Family diving, lobstering, multi-diver sessions, and extended shallow-water diving | Travel, boat maintenance, pool service, underwater exploration, and solo shallow-water diving |
| Portability | Varies widely; many systems are larger and heavier | More capable multi-diver floating system; less gear than multiple scuba tanks | Ultra-portable backpack-style system |
| Power Source | Gas, electric, or battery depending on model | Gas-powered models and Sea Lion battery-powered models | Rechargeable battery-powered system |
| Runtime | Often extended while powered and properly supplied | Up to 3+ hours depending on model and configuration | Up to 3+ hours with extended battery |
| Max Depth | Depends on system design and configuration | Up to 65 ft on select models/configurations | Nomad up to 30 ft; Nomad Mini up to 15 ft |
| Travel Convenience | Often bulkier than compact personal systems | Excellent for multi-diver capability, but larger than BLU3 | Designed for portability, travel, and fast setup |
Where Brownie’s Third Lung Systems Excel
Brownie’s Third Lung systems are a strong choice for divers who want a more powerful surface-supplied air system with longer runtime, multi-diver capability, and proven use in family diving, lobstering, and boat-based diving.
For example, Brownie’s Sea Lion brings battery-powered convenience into the Third Lung family while still offering the larger-capacity feel many Brownie’s customers expect.
If your goal is to support multiple divers or replace the hassle of managing several traditional scuba tanks, Brownie’s Third Lung can be a better fit than a smaller ultra-portable system.
Why Divers Choose BLU3 Instead of a Traditional Diving Hookah
BLU3 was created for divers who want the benefits of surface-supplied air in a much smaller, quieter, and more portable package.
With Nomad and Nomad Mini, there are no scuba tank refills required for normal use. Instead, divers recharge or swap batteries, set the floating unit on the surface, and breathe through a regulator connected to the system.
That makes BLU3 especially useful for boat owners, yacht crews, pool service professionals, underwater photographers, sailors, RV travelers, and recreational divers who want convenient shallow-water access without a full scuba setup.

Explore Nomad MiniWhat Divers Like About BLU3
“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!”
— Hal Lawson“Just starting with my nomad mini – three dives in and loving it. Really well designed, feels 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.”

Is BLU3 a hookah diving system?
BLU3 is a battery-powered surface-supplied tankless dive system. It works differently from many traditional hookah diving systems because it was designed around portability, shallow-water diving, and compact personal use.
Is Brownie’s Third Lung better than BLU3?
It depends on the use case. Brownie’s Third Lung systems are excellent for extended sessions, multi-diver setups, family diving, and lobstering. BLU3 is better suited for ultra-portable shallow-water diving, travel, boat maintenance, and quick setup.
Can BLU3 replace scuba tanks?
For many shallow-water use cases, BLU3 can reduce the need to carry scuba tanks. It is not a replacement for all scuba diving, especially deeper dives, but it can be a practical alternative for shallow-water exploration and maintenance.
