What Brownie’s THIRD LUNG™ does

Brownie's THIRD LUNG™ is a Pompano Beach, Florida-based designer and manufacturer of surface-supplied air (hookah/tankless) diving systems, founded in 1969 and operating as a wholly owned subsidiary of publicly traded Brownie's Marine Group, Inc. (OTCQB: BWMG). The company's core technology floats a compressor on the water surface and delivers breathing air to tethered divers via hose, eliminating the 38 lb scuba cylinder from the diver's back; proprietary components include the Peleton™ shared-workload hose configuration, Quick Release Swivel fittings, Drop Weight Cummerbelt™ weight-integrated belt, direct-drive compressors with stainless steel bearings, and a Variable Speed compressor control system. With 11–50 employees, the firm has built a 50-year brand recognized as the leading name in tankless recreational and light-commercial diving.

The product portfolio is organized into five lines: floating battery-powered systems (Sea LiON™ 24V lithium-ion, BLU3 Nomad and Nomad Mini), floating gas-powered systems (Scout, Pioneer, Explorer), built-in vessel systems (BIAS with BOS battery and Express Diver AC variants), land-based commercial units (Monster, Kraken, Beast) and portable electric units, plus safety accessories (Egressor™ mini scuba, Spare Air®, 3DBUOY™ dive flag) and Bright Weights® weighting products. Pricing spans $1,649 (Nomad Mini) to $7,995 (Sea LiON PRO), with commercial and BIAS installations priced on consultation. The Egressor, Drop Weight Cummerbelt, Peleton hose, QRS, and 3D Buoy are registered trademarks.

Revenue is generated through one-time hardware sales, recurring accessories and replacement parts, factory-direct service, authorized service center repairs, trade-in/core exchange programs, and $95 paid online training for used-system owners. Go-to-market combines direct-to-consumer e-commerce via browniedive.com, a global dealer network ("Find a Dealer / Become a Dealer"), factory-direct enterprise programs with engineering support for yacht BIAS integrations, and authorized service centers. Customer segments include recreational boaters, yacht owners and charter operators, commercial/professional divers, and eco-conscious resorts and dive charters. Distribution and training partnerships with Ocean Technology Systems (OTS), SEAC Sub, scuba-training.net, and the Carter Viss Foundation supplement the core hardware business.

Broad incumbents

• SCUBAPRO (Johnson Outdoors): Premium scuba diving brand owned by Johnson Outdoors, offering regulators, dive computers, BCDs and full diving systems. Comparable to Brown's as a higher-end incumbent serving recreational and technical divers, but operating through a much broader portfolio and global dealer network.
• Aqualung (Aqua Lung International): One of the largest established scuba and diving equipment brands globally, offering regulators, BCDs, masks and breathing-air components. Comparable to Brown's as a broad-line competitor addressing the same recreational diving customer, though without Brown's tankless/hookah specialization.
• Cressi-sub: Italian heritage scuba, snorkeling and freediving equipment brand. Comparable to Brown's as a long-established diving equipment manufacturer addressing recreational water users, though operating at much broader scale across all diving segments.
• Mares (Head): Italian scuba diving and snorkeling equipment brand, part of the Head Group, offering regulators, fins, masks and full dive systems. Comparable to Brown's as a broad-line diving equipment incumbent serving the same recreational diving customer base globally.

Direct peers

• LIQUID AIR (Hookah Diving): Hookah/portable diving system maker targeting recreational boaters and yacht owners with surface-supplied air solutions. Comparable to Brown's as the most direct head-to-head competitor in the tankless/hookah diving category it defined.
• Poseidon Diving Systems: Swedish maker of advanced recreational and technical diving equipment, including surface-supplied / hookah systems. Comparable to Brown's as a diving system innovator with proprietary technology and a focus on safety-oriented design for serious recreational divers.
• Halcyon Dive Systems: US-based technical and recreational diving equipment manufacturer focused on innovation and quality. Comparable to Brown's as a smaller, engineering-driven US diving brand with strong IP and loyal customer base in the technical diving community.

Emerging players

• Bauer Compressors: Industrial and breathing-air compressor manufacturer with a marine/diving product line (high-pressure breathing air compressors). Comparable to Brown's through its compressor core technology and shared customer base of breathing-air users; overlaps with Brown's compressor manufacturing capability.
• Dive Rite: US-based manufacturer of technical and recreational diving equipment including regulators, lights, and surface-supplied accessories. Comparable to Brown's as a smaller US specialty diving equipment maker with engineering-led product development and a loyal technical diving following.

Others
