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.[1]

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 nonswimmers in case of emergency.[citation needed]

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

  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).

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.

Trek Systems in Operation[edit]

Sea Trek system is now used as an underwater walking helmet in places like:

  • St Maarten[3]
  • George Town, Grand Cayman[4]
  • Xelha Park, Mexico[5][6]
  • Cozumel - Mexico[7]
  • Carnival Cruise Lines[8]
  • OdySea Aquarium, Scottsdale, Arizona USA[9]
