Review TUSA Scuba Diving Regulator

The Tusa RS-671 is a high-performance scuba diving regulator designed for those who demand reliability and durability in their underwater equipment. This regulator is part of Tusa's professional grade RS series, engineered to meet the needs of technical and recreational divers alike.

The heart of the RS-671 is its first-stage mechanism, which features a balanced diaphragm design for superior breathing performance. This design allows the diaphragm to expand and contract evenly, providing a constant and consistent airflow to the second stage. The first stage also includes a high-flow, chrome-plated brass piston, which enhances efficiency and reduces resistance.

The second stage of the RS-671 is a balanced, pneumatically-balanced, and downstream demand valve design. This means that the airflow is balanced both horizontally and vertically, providing a smooth and effortless breath. The second stage also includes a compact design, which reduces drag and makes it easier to maneuver in tight spaces.

The RS-671 is built with durability in mind. The first stage is constructed from seawater-resistant materials, including marine-grade brass and stainless steel, which resist corrosion and ensure long-lasting performance. The second stage is protected by a tough, over-molded rubber housing, which shields it from impacts and prevents damage.

The regulator comes with a number of additional features to enhance the diving experience. These include an adjustable inhalation effort knob, which allows divers to customize their breath for different diving conditions, and a purge button, which makes it easy to clear water from the second stage. The RS-671 also includes a high-pressure hose, which is suitable for use with nitrox mixtures up to 40% oxygen.

Overall, the Tusa RS-671 is a top-of-the-line scuba diving regulator that delivers exceptional breathing performance, durability, and versatility. Whether you're a technical diver exploring deep wrecks or a recreational diver enjoying the underwater world, the RS-671 is the perfect companion for your adventures.

The TUSA RS-671 scuba diving regulator is a popular choice among divers due to its reliable performance and features. Here are some pros and cons that may help you make an informed decision about purchasing this regulator.

1. High-performance pneumatically-balanced diaphragm first stage offers excellent breathing performance and resistance to freezing.

2. Second stage features a large, easy-to-grip purge button, a comfortable orthodontic mouthpiece, and a adjustable inhalation effort knob.

3. Compatible with both left-hand and right-hand hose configurations, making it suitable for divers with different preferences.

4. Durable construction with chrome-plated brass components and a high-impact, heat-resistant plastic body.

5. Equipped with an interchangeable soft-grip grip knob, a VIVA ( Visual Indication of Working Pressure ) system, and a DiverAlert 2nd stage clutch mechanism.

1. The TUSA RS-671 regulator may be more expensive compared to some other options in the market.

2. Some divers have reported that the regulator's second stage can produce a slight amount of free-flowing when not in use, which may require additional maintenance and attention.

3. The regulator's hoses, although durable, may need to be replaced more frequently compared to some other brands.

The TUSA RS-671 scuba diving regulator offers excellent performance, versatility, and durability, making it a great investment for serious and recreational divers. However, its higher price point and potential need for additional maintenance may be drawbacks for some. Ultimately, the decision to purchase this regulator depends on your personal diving needs, preferences, and budget.

If you are looking for a high-performance, reliable, and durable scuba diving regulator with advanced features and customization options, the TUSA RS-671 is an excellent choice. However, if you are on a tighter budget or prefer a simpler regulator with fewer moving parts, you may want to consider other options. It's always recommended to try out the regulator in person or consult with a dive shop professional before making a purchase.
