Review OCEANIC Alpha Octo Octopus 2nd Stage Regulator Scuba Dive Yellow #5816

The Oceanic 5816 Alpha Octo Octopus Regulator is a high-performance scuba diving regulator designed to deliver consistent and reliable airflow, ensuring an enjoyable and safe diving experience. This regulator is part of Oceanic's Alpha Series, which is known for its advanced features and exceptional build quality.

The 5816 Alpha Octo comes with an Octo valve, which serves as a backup breathing source for the diver. This Octo valve has a large, easy-to-grip purge button that can be used to clear water from the mouthpiece, ensuring a clear breathing path at all times. The Octo valve also features an over-molded, ergonomic design for added comfort and a Dive/Pre-dive switch to allow the diver to control the flow of air to the Octo valve.

The first stage of the regulator is a balanced diaphragm design, which provides superior performance and resistance to freezing. The diaphragm design also helps to reduce the amount of inhaled water and ice, making the regulator more comfortable to use in cold water environments. The first stage is also equipped with a high-flow exhaust port, which helps to reduce the amount of bubbles produced during the exhale, improving visibility for the diver and those around them.

The second stage of the regulator is a pneumatically-balanced design, which ensures consistent airflow and effortless breathing, even in challenging diving conditions. The second stage features a large, fold-down purge cover that makes it easy to clear water from the mouthpiece. The second stage also has a Comfo-bite mouthpiece, which is designed to fit comfortably in the mouth and reduce jaw fatigue.

The 5816 Alpha Octo Octopus Regulator is built with high-quality materials and components, including stainless steel and chrome-plated brass. It is also designed to be easy to maintain and service, with accessible components and a simple disassembly process. The regulator comes with a lifetime warranty on the first stage and a one-year warranty on the second stage, reflecting Oceanic's commitment to quality and customer satisfaction.

In summary, the Oceanic 5816 Alpha Octo Octopus Regulator is a high-performance, reliable, and comfortable regulator that is perfect for any level of scuba diving. Its advanced features, exceptional build quality, and commitment to customer support make it a top choice for divers around the world.

The Oceanic 5816 Alpha Octo Octopus is a popular scuba diving regulator model known for its versatility and advanced features. Here are some pros and cons to help you make an informed decision about purchasing this regulator:

1. Octopus design: The Octopus hose on this regulator can be used as an alternate air source for a buddy in case of an emergency.

2. Breathing performance: The regulator delivers consistent and reliable airflow, ensuring comfortable breathing even in challenging diving conditions.

3. Adjustable venturi initiator: This feature allows divers to adjust the amount of air flowing through the exhaust to control their buoyancy more effectively.

4. Diver adjustable intermediated pressure (DAP): This feature allows divers to fine-tune the regulator's performance based on their personal preferences and diving conditions.

5. Durable construction: The regulator is made of high-quality materials, ensuring it can withstand the rigors of regular use.

1. Price: The Oceanic 5816 Alpha Octo Octopus is a premium regulator, and its price point may be out of reach for some divers.

2. Complexity: The regulator's advanced features can make it more complex to use compared to simpler models, which may require additional training and maintenance.

3. Size and weight: The regulator is larger and heavier than some other models, which may make it less ideal for travel or for divers who prefer a lighter setup.

In conclusion, the Oceanic 5816 Alpha Octo Octopus is a high-performance regulator with advanced features that can benefit experienced and serious divers. Its price point, complexity, and size may be drawbacks for some, but its consistent breathing performance, adjustability, and durability make it a worthwhile investment for those who prioritize these features.

Based on the information provided, I would recommend this regulator to experienced divers who prioritize advanced features, reliability, and performance in their diving equipment.
