Brownies Third Lung

As the original tankless diving manufacturer, Brownie’s THIRD LUNG™ has over 50 years proven experience in engineering the highest quality standard of family friendly diving systems in the industry. Our priority is safety for you and your family. A single tank of fuel will allow 2 to 4 divers to enjoy an average of 3 hours of underwater fun, without the weight of heavy tanks on your back.

Brownie’s THIRD LUNG™ takes every opportunity to design features that benefit you as the diver.

Brownie’s Quick Release Swivel fittings allow for an easy assembly of your hose and guarantee the hose to swivel underwater eliminating entanglement.

Brownie’s undermount regulator eliminates jaw fatigue and keeps your hose more streamline under your arm.

Brownie’s specialty designed boat-shaped float tube cradles the system at a low center of gravity providing optimal stability in the water.

Brownie’s weight-integrated cummerbelts are one-size-fits-all and allow you to drop your weights in a second if need be while always staying connected to your diving system.

These are just a few of the details we have put into our systems to make diving Easier for you, Easier for everyone! Pick yours up today at Aqua Flight.
