Exploring the R22 and R22J Trieste Regulators: A Dive into Dive Gear History
Introduction to Vintage Regulators
Dive enthusiasts, gear up for a fascinating journey into the world of vintage scuba equipment with the R22 and R22J Trieste regulators. Cataloged from 1966 to 1970, these remarkable models hold a special place in the history of underwater exploration. Notably, they boast innovative features and unique design elements that continue to captivate divers today.
Innovative Two-Stage Balanced Mechanism
At the heart of the R22 and R22J Trieste regulators lies a two-stage, balanced mechanism. This engineering marvel represents the era’s commitment to enhancing underwater breathing performance. As a result, these regulators provided both reliability and efficiency beneath the waves. Consequently, divers could trust in their performance during deep-sea adventures.
US Divers’ Unique Contribution
US Divers, a prominent name in the diving industry, did not produce a comparable model to the R22 and R22J Trieste regulators. Therefore, these regulators became distinctive and sought-after by divers looking for superior performance and craftsmanship. This uniqueness further adds to their appeal and historical significance.
The R22J and Its Integral Reserve Unit
The R22J version of the Trieste regulator introduced an integral 300psi reserve unit, which significantly enhanced safety and peace of mind for divers. On the other hand, those with the R22 version had the option to add the reserve unit later. This flexibility allowed divers to customize their equipment according to their needs.
Evolution and Versatility of Ports
Initially, early production models of the Trieste regulator featured only a high-pressure (HP) auxiliary port. However, as the design evolved, later versions incorporated both low-pressure (LP) and HP ports. Consequently, this upgrade greatly enhanced the regulator’s versatility and functionality, providing divers with more options.
Distinctive Design Elements
The Trieste regulator is renowned for its distinctive design elements. For instance, it features black hoses, an “hourglass” mouthpiece with unique lettering, and nylon hose clamps. These details made the Trieste instantly recognizable and set it apart from other models of the era.
Voit’s Trieste II Version
Voit, another esteemed name in diving, produced its version known as the Trieste II. Mechanically identical to the Swimaster version, the Trieste II featured a blue label and a curved mouthpiece. Additionally, both versions boasted box assemblies finished in shiny chrome, which further enhanced their aesthetic appeal.
Coupled Reserve Mechanism in the V1-JR Model
For divers seeking a factory-coupled reserve mechanism, the V1-JR model was the solution. This regulator, which featured the same TRIESTE R22 design, included the reserve mechanism directly from the factory. The label proudly displayed the letter “J” next to the word TRIESTE, indicating its integrated reserve unit.
