Sea Trek (diving system)

In 1999 Sub Sea Systems, Inc., introduced Sea Trek, a recreational underwater free-flow open-bottomed helmet diving system marketed as suitable for people with no previous diving experience.[1]

Current Sea Trek operations vary in depth from 3 to 10 meters.[1] The maximum depth is not a function of the system's ability to provide air supply (operating pressure of 80 p.s.i.), rather a function of what the manufacturers consider a safe operating depth for non-swimmers in case of emergency.

Air can be provided from one of three options:[2][3]

1. Surface supply from an electrically driven compressor system with backup supply from high pressure cylinders via a floating manifold, through 60 ft buoyant hoses.
2. Self contained high pressure cylinder carried by the diver on a stainless steel backplate (scuba system),
3. 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 (A/C & D/C), providing the following primary functions:[2]

• 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 (visual and audible).
