In 1999 Sub Sea Systems, Inc., introduced Sea Trek, a recreational underwater helmet diving system. Sub Sea Systems is certified by ship building societies such as Bureau Veritas, American Bureau of Shipping, and Korean Registry of Shipping.Current Sea Trek operations vary in depth from 3 to 10 meters. The maximum depth is not a function of the system's ability to provide air supply , rather a function of what is a safe operating depth for nonswimmers in case of emergency.Air can be provided from one of three options: Surface supply from an electrically driven compressor system with backup supply from high pressure cylinders via a floating manifold, through 60 ft buoyant hoses. Self contained high pressure cylinder carried by the diver on a stainless steel backplate , The POD system uses two air cylinders supported by a float at the surface connected to up to two helmets by 20 ft buoyant air lines.The surface supplied compressor air delivery is controlled by a microprocessor digital control system , providing the following primary functions: Independent monitoring of input and output power to each compressor motor Automatic compressor selection and control Emergency tank activation Primary air tank pressure monitoring Downstream system pressure monitoring Low-pressure and power failure alarm .
