Review AQUA LUNG Legend Diaphragm Front Cover Purge Button Scuba Dive Regulator #5661

The Aqua Lung 5661 Legend Diaphragm Front Cover Purge Scuba Dive Regulator is a high-performance breathing instrument designed for serious divers who demand the best in underwater breathing equipment. This regulator is part of Aqua Lung's legendary series, which has been trusted by divers for decades for its durability, reliability, and innovative design.

The 5661 Legend regulator features a diaphragm design, which separates the breathing and gas supply functions, allowing for better performance and easier maintenance. The diaphragm is made from a durable and flexible material, ensuring smooth and effortless breathing.

One of the standout features of this regulator is the front cover purge function. This feature allows the diver to clear the regulator's first stage exhaust port of water with a simple push of a button. This is a crucial function when diving in heavy surf or rough conditions, as it helps prevent water from entering the regulator and disrupting the flow of air.

The 5661 Legend also comes with a comfortable orthodontic mouthpiece that fits securely and naturally in the mouth. The mouthpiece is made from a soft and flexible material that reduces jaw fatigue during long dives, making for a more enjoyable diving experience.

The regulator's first stage is made of chrome-plated brass, which provides excellent heat exchange and resistance to corrosion and fouling. The second stage is made of technopolymer, a durable and lightweight material that resists impact and UV light.

The 5661 Legend is also equipped with an adjustable inhalation effort knob, which allows the diver to easily adjust the resistance of the regulator's breathing effort to their preference. This feature is particularly useful for divers with respiratory conditions or for those who prefer a lighter breathing effort.

Lastly, the regulator comes with a Dive/Gauges hose that can be easily connected to a submersible pressure gauge or a dive computer, allowing the diver to monitor their depth, air pressure, and dive time.

In summary, the Aqua Lung 5661 Legend Diaphragm Front Cover Purge Scuba Dive Regulator is a high-performance and reliable breathing instrument designed for serious divers. Its diaphragm design, front cover purge function, and adjustable inhalation effort knob make it a top choice for those who demand the best in underwater breathing equipment.
