Airline by J-Sink vs Brownie’s Third Lung
Surface-Supplied Diving System Comparison
If you are researching the best hookah diving system or surface-supplied diving system for lobster diving, reef diving, spearfishing, hull cleaning, or family diving from boats, you have likely come across both Airline by J-Sink and Brownie’s Third Lung.
While both brands offer gasoline-powered surface-supplied diving systems, Brownie’s Marine Group has built a broader ecosystem of diving platforms including portable battery-powered diving systems, multi-diver battery platforms, traditional gasoline systems, emergency backup air systems, and marine compressor platforms.
Today, Brownie’s Marine Group includes Brownie’s Third Lung, BLU3, Sea LiON, Spare Air, LW Americas / YachtPro, and SeaNXT Americas.
This allows divers to choose from a wide range of systems depending on portability, number of divers, battery vs gas preference, diving depth, runtime, and intended marine applications.

Gas-Powered Diving Hookah System Comparison
While Brownie’s Marine Group offers battery-powered systems like BLU3 and Sea LiON, Brownie’s Third Lung remains one of the most recognized names in gasoline-powered surface-supplied diving systems.
Brownie’s gas systems were developed specifically for real-world marine applications including lobster diving, family diving, reef diving, spearfishing, underwater maintenance, and repeated deployment from boats.
Compared to more traditional hookah system layouts, Brownie’s systems place strong emphasis on lower center of gravity, buoyancy, hose management, marine-focused float design, quick disconnect systems, and long-term dealer/service support.

Why Brownie’s Uses Custom Diving Compressors
Brownie’s Third Lung systems use purpose-built diving compressors and marine-grade materials designed specifically for surface-supplied breathing air applications. Rather than relying heavily on more off-the-shelf compressor layouts and painted steel components, Brownie’s systems utilize hardcoat anodized aluminum, stainless steel hardware, RF-welded marine floats, and custom dry snorkel air intake systems engineered for harsh saltwater environments.
Brownie’s has been refining surface-supplied diving systems since 1969, with a design philosophy focused on long-term corrosion resistance, stability, breathing performance, and real-world multi-diver usability. Features like the Peleton Hose System™, QRS Swivel quick disconnects, lower center-of-gravity float layouts, and custom vertical dry snorkel air intake systems help differentiate Brownie’s systems from many traditional hookah diving platforms.
Whether you are lobster diving, reef diving, family diving, or performing extended bottom-time applications, Brownie’s systems are designed around marine durability, serviceability, and long-term reliability.

Why Divers Choose Brownie’s Third Lung
Many surface-supplied diving systems focus primarily on basic air delivery. Brownie’s systems were designed around the complete marine diving experience.
That difference becomes especially noticeable during lobster diving, multi-diver operation, repeated daily deployments, reef diving, and extended in-water sessions.
Brownie’s systems emphasize lower center of gravity, increased buoyancy, reduced hose drag, cleaner hose management, RF-welded marine floats, quick disconnect systems, and broader dealer/service support.
The Brownie’s ecosystem also gives divers the flexibility to choose ultra-portable BLU3 systems, battery-powered Sea LiON platforms, or traditional gasoline-powered marine diving systems.
