What is an Aqua-Lung? In its simplest form, it is a self-contained, open-circuit breathing apparatus. Aqua-Lungs, one of the earliest types of self-contained breathing apparatuses, quickly became popular and commercially successful. This equipment is commonly known as a twin hose diving regulator or demand valve. Aqua-lungs were first used by Emile Gagnan and Jacques Cousteau. They quickly became a hit in the diving world.
Jacques Cousteau
Jacques Cousteau, in the 1940s, created the first underwater breathing apparatus that was self-contained and open-circuit. Cousteau's design was based upon a demand valve system, which supplied compressed air to divers while they were underwater breathing. This device, called the Aqua-Lung (or the Aqua-Lung), opened the world up to divers and anyone else who was interested in diving. Aqua-Lung, designed by Cousteau, became the standard in diving.
Emile Gagnan
Emile Gagnan, Jacques-Yves Cousteau, and Emile Gaunin invented the Aqua Lung in 1940. Its innovative design was derived from the earlier designs of diving helmets in the 19th century. It allows underwater divers breathe through a mouthpiece which releases compressed air when activated by their breath. Gagnan developed the regulator valve for the device. It automatically delivers compressed air to diver's mouthpiece according to diver's breath. This device was a significant breakthrough in the diving world, allowing people to explore depths of ocean for scientific observation, military and recreational use.

The first open-circuit demand regulator
Cousteau invented the Aqua-Lung in 1944, and it was patentable in 1946. The Aqua-Lung has been a favorite scuba regulator for many years. Gagnan, Cousteau’s father-in law, and Emile Gagnan his French colleague were also part the team. They all knew Cousteau’s research and decided that they would collaborate to create Aqua-Lung regulator.
The BC1
The BC1 Aqua Lung (an advanced back inflation BC) is designed for commercial, military and public safety divers. With its rugged design, it offers superior comfort, fit, and stability. The manual contains information about how much weight can be placed into each pouch. Two weight capacities are available for the BC1, one one chest and one one back. By purchasing different weight pouches, the BC1 can be tailored to suit individual needs.
The Titan
Aqua Lung Titan is a portable, lightweight regulator that incorporates all the features of previous generations. Its lightweight design allows for easy use. A soft polyurethane wrap provides a snug fit. Its sturdy and lightweight design makes it easy on the dive boat. Its price is moderate, making it affordable for many people. There are two stages to the device, with a second that stops unwanted freeflow.
The Mentor
Aqua lung Mentor is a regulator created in collaboration with USA Navy. This regulator replaces the older double-hosed regulators that are used to teach divers how to rebreather. The Aqua lung is not yet available to the public but it is an excellent option for professional divers who are looking for an alternative for the double-hose regulators. Be aware of these things when purchasing the Aqualung Mentor. You must first calibrate it.

The Sea Hunt
The Sea Hunt was a TV series that ran from 1958 to 1961. It starred Lloyd Bridges in the role of a Navy-frogman. It was a huge success and attracted phenomenal ratings. The series has been a perennial favorite among Boomer viewers, and it's been rerun for decades. You can now buy a complete box set that includes all 39 episodes. TGG can offer the set as a 5-disc, two-volume box set. It is still action-adventure, with 26-minute episodes.
