The SS1 contains a high flow second stage that performs on the same level as many high performance second stages. It will deliver high flow rates to a diver at depth with a minimum of effort. It is, however very stable and not prone to unnecessary free-flow or leakage from water movement while swimming, or during entries or exits. The inflator/deflator is easy to operate with soft surfaced buttons placed where they can be easily operated with one hand. Durability and Dependability The SS1 regulator incorporates the patented Atomic Aquatics "Seat Saving Orifice" found in all of our second stages. This feature prevents wear and deterioration of the low-pressure seat and in partly responsible for our unparallelled 2-year service interval on this product. The SS1 is constructed of quality materials not found in any other Safe Second on the market. The quick disconnect coupling, regulator valve body, and inflation and deflation stems are machined from type 316 stainless steel to avoid corrosion that would eventually degrade performance and function. The regulator orifice and lever are titanium for maximum strength and reliability. Adaptability One of the most unique features of the SS1 is its adaptability to almost any BCD. We have designed a set of adapters (patent pending) to fit virtually every poplar BCD brand available (and many that are not). The adapters also include components for attaching the cable exhaust feature of your existing BCD (if applicable). Convenience The SS1 features a quick disconnect not only on the low-pressure hose, but the BCD hose as well. The adapters that fit the SS1 to the BCD are connected to the SS1 with a threaded collar that can be easily unscrewed to detach it completely from the BCD. Now you can carry or store the SS1 with your primary regulator of gauges (patent pending). The SS1 has a low profile elliptical shape that lies flat on the BCD. The control buttons are large and easy to find. The entire front cover is a flexible elastomer that functions as the purge button for the regulator. The SS1 offers pneumatic or oral inflation for buoyancy control and back-up breathing in one small package.
