Met the most amazing people at Brownies this morning. I got hustled by someone on marketplace for a used third lung, and the people at Brownies, Heather and Mike, were so kind and hospitable. They took the old unit off my hands and hooked me up with a great deal. All while treating me like family walking me through the entire operation and going out of their way to give me amazing tips and pointers. This is the kind of service that all other business should model themselves by. They literally saved the day for my daughters. Can’t wait to get this thing out on the water. Thanks again Heather! scratch Tsunami for me!!
I was FLOORED by the level of Customer SERVICE at Brownie's Third Lung! Heather helped me set up getting some work done on my older equipment, and she was GREAT! Communication throughout the process was timely and accurate. She knew what needed to be done and how long it would take. Return shipping to me was FAST and on time. I would not hesitate to work with BTL next time I need Service.
What an awesome experience! Jack is the best, he was very helpful in showing me the operation of my Nemo Dive system. The coolest device to see the underwater world without the scuba diving equipment. You guys rock!!
I own six Brownie Third Lung, compressors of various types from belt driven to direct drive And from Standard style to commercial these are my every day use equipment because they’re rugged they’re durable and if they do have a problem, they’re easy to work on I won’t use anything else.
Used my brownie hookah three times. Warranty expires after 1 year. The third time I tried to use it is when it stopped working. Called brownie and spoke with them about the issue. The answer was for me to ship it to them and they will determine whether it’s a part defect or not. The shipping cost to ship it is $200.00 each way. At this point I will be buying a better brand hookah and learned my lesson the hard way. If you’re looking for a good hookah the check out Keene engineering. Been using my friends for about a year with no issues.
This place really has it going on!!!! I am one of those slackers that just took my unit in this week to get ready for mini season. I am terrible at caring for my unit and that thing needed a lot of work but they made it happen for me. The mechanics mike and Jerry were very knowledgeable about the configuration of these systems making it easy for them to get me back out on the water. I also would love to give a big shout out to heather and Stacy in the office these girls know everything about these systems from how to care for them and even the mechanics of the system heather even gave me tons of pointers on how to care for my system and how to keep it in the best condition. Lastly they have a great shipping dept and Claude was able to get my unit shipped out to me in the keys in no time at all. I love this product and especially this company for always treating me so fair they really do value their business and their customers…. Thank you Brownies!!!!!!

Whether you’re a seasoned diver or just starting, our tankless solutions provide freedom and flexibility. With options like the Sea LiOn™ and our battery-powered systems, you can enjoy longer dives and greater mobility, making every underwater adventure memorable.
Understanding the Benefits of Tankless Diving
Tankless diving systems revolutionize the way divers experience underwater exploration. By eliminating the need for heavy tanks, divers can move more freely and comfortably, focusing on enjoying the marine environment rather than managing cumbersome equipment.
These systems also promote longer dive times and reduced physical strain, making them ideal for recreational divers, underwater photographers, and professionals alike. With features tailored to enhance safety and ease of use, tankless diving opens up new possibilities for exploration.
Comparing Battery-Powered vs. Gas-Powered Diving Systems
Choosing between battery-powered and gas-powered diving systems can significantly impact your diving experience. Battery-powered systems, like the Sea LiOn™, offer quiet operation and zero emissions, making them environmentally friendly and perfect for close encounters with marine life.
On the other hand, gas-powered systems deliver robust performance for longer dives and are often preferred by commercial divers needing extended air supply. Understanding the advantages and limitations of each option helps divers select the system that best suits their needs and diving style.
