In 1999 Sub Sea Systems, Inc., introduced Sea Trek, a recreational underwater helmet diving system.

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 (operating pressure of 80 p.s.i.), rather a function of what is a safe operating depth for non-swimmers in case of emergency.[citation needed]

Air can be provided from one of three options:[1]

  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:[1]

  • 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).

Sea Trek Adds Underwater Wheelchair[edit]

In 2015, Sea TREK operator Native Diving Lanzarote in Spain added a modified wheelchair utilized to take guests with limited or no use of their legs on an underwater Sea TREK tour. Sub Sea Systems was inspired by this and developed a custom underwater wheelchair specifically designed to be used with the Sea TREK system. This program is called Adapted Sea TREK and will be available at multiple Sea TREK locations worldwide.
